While Ryobi might very well be over-estimating the capacity, another thing you completely looked over is how capacity falls depending on current draw. If you discharge those batteries more slowly (like on their soldering iron, or the jobsite fan), chances are you will get a runtime closer than the theoretical calculations. However, if you use higher drain tools like a big drill or the blower, you'll get less capacity, since the higher current flow means more power will be lost to heat within the battery as well as any cables or contacts.
Good point
Yes! Thank you! I was going down the comments to see if there was anyone who understood simple physics! There is no "100% efficient" anything out there. There are ALWAYS losses in friction, resistance ect. The extra power that was "missing" actually was spent by being turned into heat. I think that the battery performed as advertised.
You stated the obvious with the amount of draw depending on what you are using. I wouldn't say he completely overlooked it.
You can do the maths yourself if you know what tool or equipment you need.
In this example he used a blower.
The video still provides the information required to understand the batteries capabilities.
Unless your a complete numbnut, which your comment will help the numbnuts out there. Cheers
Yes, but breakdowns of the batteries, to look at the actual cells contained within, often show that the cells themselves have a lower max capacity than is actually being advertised.
This is basically battery abuse. Asking the battery to output TWELVE AMPS for the entire time? A 1.5Amp hour battery is designed to run for an hour at 1.5 amps (technically, 1C) or 1A for 1.5 hours (0.66C). It is not designed to run at 12A (6C, 6 times as fast a discharge rate), and I'm amazed it put that out for any length of time at all.
A battery that runs continually gets hotter (power loss) and will deliver less energy the hotter it gets.
Conversely, starting an electrical motor has a higher draw than on that is already spinning.
A test involving shorter runs would simulate real world use more accurately and give you numbers closer to the theoretical rating listed on the battery.
All that said, I enjoyed the video and appreciate your effort. You have earned a like and subscribe, sir.
Awesome - make sure you check out my latest blower video - you will love it
3 years later and this is still a great video. Well done!
Thanks mate - glad that it has stood up to the test of time
@@Kitearmy Is it going to give my brushless impact driver more POWER if i use a 5ah instead of my 2.5ah, meaning actual torque/power for better performance?
@@themototo10 nope
This was a great explanation and exactly what i was looking for. Great job!
Thanks mate!

Thanks for the video. I just converted a snowblower to run on 2 series connected Ryobi batts. Knowing they can push 12A lets me know they'll work.
Glad I could help
While my Dewalt 60 volt right angle drill is the king of the Category I just can’t justify that price level on every tool and the Roybi Hand drills and Saws hold up well in hard Industrial use and the new 6 amp battery’s really sealed the deal
I get the cost thing...but I in my experience I never felt that any Ryobi tool I used was capable of hard industrial use. Very cool that they work great for you.
tommays56 or the 9amp battery coming and other good power tools for that kind of battery.
Ryobi is coming out with a 9Ah - cool
@ Kite Army:
Yep...just ordered 2 of the the 9ah batteries @ Home Depot...a "Special Buy" item presently (given the Holiday Season I suppose) but still pricey: A 2-pack for $159.99. Plan to use the largeer-capacity batteries for any cordless "benchtop" Ryobi tools I get.
-- BR
Frankly, in industrial use all tools and batteries get pooped. For home use I got Ryobi tools cause they strong enough and cheap.
Good video. Can you paste a link to the song you played during testing? I've look for it on RUclips but I can't find that exact track.
Surprised you could not find it as it is a famous protest song.... Blowing in the Wind, written and performed by Bob Dylan. Peter Paul and Mary also covered it, as did Pete Seger.
Thanks, your video was very helpful. It explained why my battery time ran so short. I have a 18v, 4Ah battery in the Ryobi One+ mower, it lasted about 7 minutes.
Glad it helped
I think that was a fairly good test, definitely good for anyone not familiar with the complexity of volts and amps and amp hours. How I will say that technically it's probably not Ryobi overstating the amp hours as pretty much all brands buy cells from Samsung, LG, Sanyo or Sony. I imagine they simply repeat the manufacturers capacity specs. Also something to consider is you will always get less runtime the faster you discharge the pack. Heat has a lot to do with it as heat is not only created by energy that's not turned into current but it also causes the cells and circuits to work less efficiently. I would think that if the manufacturer tests the capacity with a half an amp or maybe 1 amp load they might get the full rated capacity before the low voltage cut off kicks in. With that said your test was very good in a real world sense, but you'll probably find very similar results out of a higher end battery.
All very good points! Thanks for comment
Great video keep up the good work. What do you think about a budget Rigid Wet Saw for DIY user . Do you have any recommendations for a wet saw? Home use
I have used this for my bathroom project: amzn.to/30KaDQN
I have the same blower I am happy with it. but your right if you have a small yard it works great. I get a lot of leaves.
Your right - this is a good blower but not good for a larger property
That was a cool video, informative & entertaining.
Thank you!
Very helpful. Thank you.
Glad you found it helpful
5:40 😆 Sir this is a family site
I couldn't help myself
How much amps did the blower pull off the battery on the 6Ah battery?
When the 4 and 6 amp hour batteries first came out, I tested them on my Icharger 410 on the discharge function. The batteries were new from their packaging and they all tested right at or slightly higher than their advertised watt hour ratings.
Oddly enough, the high current stall that happens on some tools seems to be the same between the 4 and 6 model. I don't think the 6 handles more current then the 4 in other words. I am waiting to get the new HP 18V batteries to see if they in fact handle heavy loads better.
I would love to hear the results
Thanks. Now I can finally make that purchase :)
cool!
Dam dude this video alone made me sub and comment lol awesome video great info
Thanks mate - welcome to the club
Amazing video 🙌🏽🙌🏽🤩 it was tooooooo clear
Awesome
Kite, I think your assessment is good, and as scientific (at least pretty accurate) as any I've seen. The question I keep in my mind when I go to make a purchase, is - does the tool do the job for what I'm looking at for the price point? Having a good base set, I only buy tools when they are on sale, so I've purchased a number of Ryobi tools that have come with a good battery set, and sometimes a "free" (OK, nothing is free!) tool. So, I have 5 of the 4Ah batteries and 1-1.5 Ah. As a result I have never run out of battery power doing anything. That said, I am very aware that there are better quality tools. If I were a pro, or even if I were to take on a large task like rebuilding a garage, I would just but the tool I think best fit the job. They last a long time these days. Another thing that happens when you get a lot of batteries like this, you start to loose perspective and are psychologically predisposed to just buying the tools to feed the existing battery pool because it is much cheaper. I have actually turned to looking at reviewers and analytic reviews such as this before purchasing. Thanks - good work!
Thanks mate....I'm certain that this test would not stand up to scientific scrutiny. That being said, for most people this video will help them make informed buying decisions and hopefully choose the best yard tool for their needs.
Thanks. Great video
Glad you liked :)
so my question is which tool /brand for the $50 more are you recommending?
for what kind of tool
For outdoor tool yes definitely need a 36v-60v system. But drills and what not ryobi works well for half time users.
very true
Helpful. Makes one think.
Thinking hurts...thanks for the comment
Can you do the same thing but with the ryobi riciprocrating saw
Blowers consume battery power like crazy - a reciprocating saw will run forever even with Ryobi batteries
Thanks for the info
Sure thing
Learn something new everyday. Very good video sir.
Thanks mate - These days I feel like I'm learning tons of things each day
Maybe I missed it but did you test how many amps were being drawn from the 6ah battery? I believe they are able to provide more current and aren't simply a higher capacity
I think it was in there somewhere
Excellent, The way you explained make us understand now , what is 1.5ah means .thank you . I would share it to my friends
I really enjoyed making this video. Glad you found it helpful!
Cool vid, thanks!
Thanks
Love the demistration, I have a ryobi 18volt 1.5 Amp battery and I was wondering if a bigger battery would give me more run time and power ,,,great demistration
Very good presentation on ah. Def informed my buying decision.
Glad to help
At 3:48 the ammeter displays 1.13 amps prior to starting the test, is something wrong or was the meter not zeroed?
good eyes - not zeroed
That 6Ah battery... was it allowing the blower to draw more than 12.5A?
That's really interesting because if it is, then the bigger batteries area also allowing the blower to be more effective and also would mean less run time.
Good explanation- really good. But I am curious. So, what's the step up platform for another 50 bucks? Do you mean a higher voltage battery platform? You mean the Ryobi 40v blower?
Very helpful. Please tell me what other platform is better? Thank you, would like to know.
For what application?
@@Kitearmy
Hi kite, I guess for garden tools
@@mikelm5384 Look at EGO for cordless yard tools they are king
Do that test with Milwaukee and there 2.0, 5.0, 9.0. and later test with new 12.0 and 6.0 with the new 21700 cells!
I wanted to see how those cells would perform against each other :0
Cool test. But I can also imagine the capacity is related to the amp draw. 1A 10hour doesn't promise 10A 1hour. Would be a more complete test if cover different amp draws.
thanks
I would like to see the same test for other manufacture batteries. Also I would like to see the amp meter during the test. Lastly I didn’t,t think lithium batteries fell off but had nearly full power until the quit.
These are low quality cells - the power fall off is huge. I intended on including the amp meter during but that would add more resistance to circuit and someone would have complained. If I get enough interest, I will revisit.
They do fall off, but not completely. It's a myth/misunderstanding that li -ion has no drop off. It does, just like any other battery. The reason that they don't, is because the electronics that manage them intentionally cut them off before you get to that point. That's to prevent you from fully draining, because if you did, you would permanently kill the battery.
OTOH, yes, they get weaker because the voltage drops. Even my Bosch tools get weaker before they cut out. You just notice it more with blowers due to very high current demands.
That's so true - that's why i choose the blower to perform this test. I didn't want to wait around all day for the battery to deplete when connect to a drill. Thanks for your helpful comments.
Kite Army they are not low quality cells. Your assumption is unfounded and based on lack of understanding of electronics and battery specifications. You could have used a clamp on meter rather than a series multimeter, or a very low ohm resistor then measure the mV drop across it which is minimal power loss.
However there seems to be a large fundamental misunderstanding about batteries by yourself and Ed Blough. Lithium Ion batteries reach approx 4.2V at full charge and discharge down to around 3.0V (due to a protection circuit that prevents over-discharge). This drop in voltage occurs with every single cell in every Li-Ion battery pack no matter the brand of pack or cell. This directly results in less current through any tool with a brushed motor and once it drops enough, will reach the peak current possible through a brushless motor too (and drain the battery that much quicker due to running nearer full output power for longer, otherwise brushless would have even more runtime benefit than they do).
I propose a different test. Get the battery spec sheet, note the current at which they attain the Ah rating, and make a resistive load for the test that results in the spec sheet current for the nominal 3.6V/cell ( x 5 = 18V pack). This eliminates the variable of which tool you are running, and all you have to do to measure the current without further loss is measure the voltage across the resistive load which then calculates out to precisely the current.
If on the other hand you just wanted to demonstrate that these 18V tools aren't fit for more than small properties, sure everyone already knew that, which is why higher voltage tools exist but frankly I wouldn't bother because you can get a reasonable gas blower for $100 and taken care of and with light repairs can last over a decade. Cordless is great for some things but I'll stick to gas for something like a blower where I don't just need runtime, I need performance too. My gas blower even mulches leaves and twigs every fall to cover flower beds over winter and for compost.
Cool comment - of course I don't agree with all your points but that's OK. I use cordless tools on my yard and am pleased with the results. I will never use gas tools again - unless at gun point. Now, the point that I was making in this video is that some cordless tools are up to the task landscaping my middle sized yard and some are not.
have you ever testing anything Kobalt related and their batteries ?
Yes in the beach ball blower bonanza
I liked your video. I felt like it was a pretty accurate real world test. I agree with some of the comments that your math was off, but disagree about why. I think it was due to rounding and not your bias against Ryobi. I feel like the test was fair. I don’t think the beach ball would really make a difference on run time.
I was curious how you measured the amps on the tool. I’m fooling around with making a corded battery for my garage. It’s not temperature controlled. So it gets super hot and super cold. And I want to be able to use my Ryobi tools out there without leaving the batteries out there.
I was hoping to figure out the amps specifically for the drill. And maybe a saw or 2.
Thanks - So, I took advanced Physics in college and one of my best professors always rounded (and I mean huge rounding - like 89=100 stuff) and it was surprising how in most cases the results were close to the real ones as long as your round fairly on both sides - for what it is worth. The tool I was using is an inductive amp meter - they are great because you don't have to be part of the circuit to measure the amps. They are more expensive than a normal meter but well worth it.
Andrew, I really enjoy the thorough approach you take with your videos. You make things very easy to understand - ironically, not an easy thing to do. I know you are testing Ryobi here, but the principles should apply to any brand obviously. Curious if you have or will do a runtime test, wot, of the EGO 56v power head unit with and without attachments and with different batteries? Asking for a friend > ruclips.net/video/FYPLNlSAFpw/видео.html
He's only getting 8:50 out of a 5ah battery using the string trimmer power head. Seems low, even on high setting, for a fully charged 5ah battery.
Finally freed up some time to catch up with my favorite vloggers and you're one of them! Had a really HEA VY week with a mini road trip, overnight camp out in my Prius and a morning surf sesh with my new wetsuit and surfboard to start the week. Then came home to work a second job Tuesday night and the rest of the week worked my regular job and I also helped install a small above ground pool for my wife and grand daughter so there wasn't any time to watch RUclips. Oh yeah...I also spent hours trying to edit my trip and surf sesh that I just vlogged. So here I am finally checking yours out...whew! Cheers, John ;) P.S. I haven't got your parcel yet...kinda weird isn't it? Hopefully it will be here soon ;)
No one's going to accuse you of being lazy....I just spent the week at the beach.

BTW...I used to be very lazy but now there's not enough hours in the day to do all the things I need and want to do...yeewww! Cheers, John ; )
you must also state if you know, that ryobi batts cut out BEFORE they come to "0" volts..why ? cause if you drain a batt 100% if will never take a charge again..its a safety cut off safe switch thats inside the batt on the pcb
True all - lithium batteries do that
That was very helpful, I was wondering why my runtime was so short.
cool
I'm pretty sure that goes for all major brands - after all, for example Ryobi, MIlwaukee, AEG and Ridgid are all owned by the same HK company. By the way, what a relief to hear good background music, instead of the usual grating noise most other channels have !
Thanks so much, though I should let you know that most of my videos have that annoying grating noise
@@Kitearmy hahah you just gave me a good laugh ! Appreciate your content !
Great info thank you. I have been wondering how much power cordless tools really deliver. In your test 12.5A * 20V = 250Watts. I have heard that the 3ah and 6ah Lithium+HP batteries can deliver as much as 46A! If so, even 18V cordless tools can be significantly more powerful than many 120V tools.
Cool - something else to consider is that the largest household powered tools normally don't exceed 12 to 15 Amps
The issue is, drawing 46A for long will just melt things. That's cranking amps for a small car! And wires rapidly get very hot at that.
What about the 9 Milliamp hour battery ? Is that thing worth the price
Remember, voltage drops during the test. It changes all the numbers. The batteries are not misrepresented the way you're saying. In fact they usually read above their factory rating. Also a 12 amp draw is a bit extreme. Most of those cells are rated at X amps at 1c rate.
I've tested dozens and they're within 5%.
12amp is extreme but that is not uncommon for cordless blowers - you are right about the the c rating. If better cells were used and they had higher c rate they would perform better. Perfect example of how Ryobi cuts costs - Good point mate :)
@@Kitearmy Ryobi uses Sony cells which are great cells.
@@jalee6587 Lots of brands use the Samsung - don't know how they compare
Glad someone else here understands batteries and physical laws!
I would love to see the same test but with Ryobi Landon I would love to know how long you could run the landing with the 4AH and a six amp hour and the nine amp hour and be able to see the difference between those batteries and I would love to know how much power the lantern draws
So it is safe to use this motorcycle battery -
- LI-ION-Technologie
-: 20 A: 48 Wh vs 20Wh / 5A?
question what amp battery do you for recommend for the 7-1/4 in. Miter Saw by ryobi and 5-1/2 in. Circular Saw? I have the 2.0 Ah Batteries, it was a combo set . 7-1/4 in. Miter Saw it ran for 25 minutes and the 5-1/2 in. Circular Saw it ran ran for 20 minutes. both battery was fully charge. any suggestions and thanks Rocky.
Go as big as you can get - I think they have a 9Ah
@@Kitearmy OK thanks you.
Just bought 2 4ah batts from home depot for $70 the day after christmas, I couldnt pass it up. I think they will help me because ive been running the little 1.5ah batts for years. I run a 3/8 impact, sawzall, and 18v tire inflator so these bigger batteries are gonna be a lifesaver I think when working on customer properties. Atleast now I also have 4 batteries instead of just 2 👌 my dad is now going to get the same deal tomorrow he was impressed by the deal
This is the best sale time of the year for Ryobi tools
Theoretically there is enough power in the batteries to hit their stated runtimes, however they will cut off before they go too low as a safety feature to stop the batteries from becoming permanently damaged on/or catching fire.
Right - they have a low voltage cut out
C rate of the new Ryobi HP Batteries make my P508 cut stronger.
Cool - I didn't know they changed the c rating
Have you tested the new 4 amp high performance battery compared to like the HP batteries
Yep - no difference as far as I can tell
Most reputable battery manufacturers quote their Ah rating for a given discharge rate, usually C/10 which means 0.6A for a 6Ah battery. Testing at a lower current, say a LED torch would produce a higher figure. Still a useful test though. It would be interesting to compare the Ryobi batteries with the cheaper off-brand models.
Great suggestion - i will put it on the list
Thankyou for this video! I feel like I have much better understanding of amp hours now, and what to expect from my cryobi battries.
Thanks for that
Good vid
Thanks mate
You forgot to mention the link between voltage and amperage, as the battery drains the voltage decreases which means amps increase thus draining it even faster, now if you could have measured the voltage during the whole test we would have gotten a very good indication of the what's what's.
Not to say it wasn't a good demonstration tho man👍
Why would a battery charge and after charging I'm assuming fully because it has all 4 bars but anyway when it's finished charging the charger starts reading defective. I have a bunch of batteries and it only does it to this particular battery on all chargers. Battery seems to work fine as far as I know. I'll drain it to 2 bars before charging. Any suggestions?
what manufacturer
From a practical standpoint I think this was a good video. It was nice seeing a real world application of some of the different battery options for the Ryobi one+ line. I’m a fan of their equipment due to their affordability so I was interested to see how their batteries stood up. However, I think your conclusion that the batteries don’t stand up to their advertised voltage/run time isn’t 100% reliable. Without controlling your variables to the exact degree advertised (1.5 amps for 60 minutes) your experiment was faulty from the start. Also, you clearly stated that the blower was pulling 12.5 amps and did your calculations based on it pulling 12. Had you accounted for the other .5 amp in your calculations then the anticipated run time would have been closer to that which it should “in theory” be capable of.
Rather, you should have said “If 1.5A = 60 minutes, then 12.5A = 7.2 minutes (or 7 min 12 secs).” Ultimately, your experiment still did not support this but, statistically, it was closer. I’d be very interested to see if it could in fact meet it’s advertised run time by controlling the exact amount of amps being pulled. Although, I’m not sure how you would go about achieving that! In the end, still a good video. Looking forward to more from you.
More to come
There is a lot more to it. The amount of current we can really draw from a battery is limited. For example, a coin cell that is rated for 1 Ah can't actually provide 1 Amp of current for an hour, in fact it can't even provide 0.1 Amp without overextending itself. However, a 1Ah coin cell has no problem providing 1mA for 1000 hours but if you try to draw 100mA from it, it'll last a lot less than 10 hours.
That blower can draw more amps than the batteries are capable of providing continuously thus losing a substantial amount of power to internal resistance. Ryobi batteries are made with multiples of 18650 batteries. 18650 lithium battery packs can sustain short bursts of high current substantially above their rating but typically for no more than 30 seconds before suffering a considerable voltage drop. Btw, the blower was slowing down because of the voltage drop not a drop in amps. In fact the amp draw was probably rising and overheating both the battery and motor as the voltage dropped. Anyway, Ryobi's standard batteries work great for most of their power tools but the blower with its continuous duty cycle would perform much better if it had the HP brushless motor with Ryobi's HP line of batteries. HP is High Performance or perhaps more accurately, high current.
From what I could find on the web:
The small battery you tested with the amp meter is rated for max 8 amp draw, 4 amp nominal
The 4Ah battery is 15 amp max
The 6Ah HP battery is rated 15 amps with a max burst of 30 amps
I must add that the blower is not HP so cannot take full advantage of the HP battery's current just its higher capacity.
Imho If you ran the 6Ah battery 5 minutes at a time and let it cool in the shade 10 minutes in between, I believe it would easily exceed your 30 minute calculation. Of course there are always variables and temperature is a big one. Obviously if it's only 40 degrees outside in the Fall (when the leaves are falling), the batteries will take longer to heat up and cool down much faster while sitting idle. A tool that draws much less current such as a radio at less than an amp will also give you significantly better results.
I will add that sadly Ryobi chose to include the cheaper 4Ah battery in this kit rather than an HP battery but then the blower would also need to be upgraded with the brushless motor and HP contacts to the battery. So there goes the average consumer who is looking for the absolute cheapest product (junk) in the misguided belief that the $40 chinese blower with a sticker claiming it blows harder than hurricane Andrew is a better deal. Well now I'm ranting so, thank you. The End
Wow - I guess you have thought a lot about this subject. I really appreciate your insight
The thing is, your meter is saying the blower is using 1.12 amps doing nothing at 3:52. I'd advise using something else to test. I know there are Fluke fans out there but I like my UEi meter just as much for the price. No Fieldpiece stuff.
Fluke fan here - just can't afford
I only have one because I used to do HVAC work. Also, the battery probably keeps around 10% or so reserve to prevent a full drain; as you probably know fully draining a li-ion battery kills it.
battery collapse - I have been working with robotics for a while and everyone pushes a battery too far once.
Thank you for the insite I know that I can have a 2ah battery but I can buy the bigger ah battery and it will still work as I'm not a professional worker more a diyer it helps
the 2ah will probably work for most DIyers
i was hoping you would cover the max current draw of these batteries before the it shuts down from over heating.
I have noticed that with the 2.5Ah battery
A leaf blower for the example used was informative but a test using more common items used with the 18 volt batteries such as drills, saws and other commonly used power tools around the house would have been more applicable for that battery pack. A leaf blower using a 40 volt battery pack regardless of the brand name would definitely be a better option. Your video was presented very well--Thanks
Glad you liked the video. I choose a blower because they have much higher power demands than some other tools. That kept the video shorter. Thanks again for your comment
The most obvious problem with your testing arises from the leads and connections made with them for your initial amp draw assessment. The additional resistance introduced by their total length and the really poor connections made by the clips would have reduced the amp draw from what was likely 15 or more to your assumed 12. You could have done an audio pitch analysis to compare frequency/Rpm or used an optical tach to see how much difference in speed there was between a directly connected battery as compared to running the blower through your leads. Note that Rpm does not increase linearly with voltage.
Note also that this blower is only pushing about 18 V × 15 A or about 270 watts which is about 1/3 of a horsepower.
Sure -thanks
"only" a quarter of a horse's power output from a battery you hold comfortably in one hand. Have you seen a horse?
I would use the full power if im really trying to push little bed rocks. Other than that, pushing leaves, grass and even mulch doesn’t require the full power. Ill keep my ryobi. But this was useful. Now i can manipulate how much run time i could get off my 4AH. Thanks buddy! Subbed!!
Great comment - welcome to the club
Kite Army - Thank you Sir!!
True for perhaps high current draw but powering a Ryobi light can be powered longer.
Sure - less power draw
Ive got a 1,5 amp battery and want to buy a brushed circular saw. Do i need to buy a bigger battery aswell? Mainly doing small projects at my small house 😊
That should work
@@Kitearmy did work!

I have some of the smaller, lithium ion Ryobi batteries. They no longer hold a charge. Is there a way to bring them back to life?
Some people claim to be able to restore lithium batteries - to some extent you probably can revive them but they will never perform as new or close to new.
@@Kitearmy Thank you! Both for a reply (quick at that!) And honesty!
@@fishingismydrug1 Glad to have helped
As a diehard ryobi fan....i would suggest your numbers are pretty close to correct....in my experience blowers really suck the juice as opposed to a drill, impact, etc....im sure other platforms can get more runtime, but essentially all the big brands are using high quality lithium batteries...so I doubt the difference would be massive...
Blowers suck up the battery power that's why i choose to do this test with a blower. Thanks for comment
@@Kitearmy so an 18v weed wacker with a 1.5Ah battery would give me more than 7 minutes? (Same brand, Ryobi)
@@AndrewDaniele87 yes - maybe
Ok, 1st thing I have to say is that you are brave to dive into the world of testing lithium batteries. Everybody out there thinks they are experts in the field and it's very hard to please these people with any type of test that anybody does. Having a bit of an electronics background I would mention that V should not be related to power ( W ) as you mentioned. V would better be related to speed... JMHO. Power ( W ) is V x A so it is the combo of the 2. I agree with you on the fact that you say Ah is related to runtime as Ah is the size of the "electron" tank and the more electrons you have to play or capacity, the longer the runtime should be. I also agree that if you increase V you increase your power...that's just math. One thing to point out is the voltage drop as the battery discharges and hence the following power decrease...which is normal. The battery does not stay at full voltage as a load is applied so that has to be taken into consideration and messes with the math. Also the motor, battery and connecting wires heat up which create resistive losses and more loss of power and runtime. If you pulsed that battery and let it recover and cool down after each pulse or short run, I bet you would get the rated runtime. These are just a few observations from years of racing r/c cars and watching a lot of EV related shows. I am certainly no expert on lithium batteries...just making observations. And speaking of that, why did your test meter show a current reading at no load? Did you "zero" the meter? I always enjoy your videos and your efforts to do demos of these battery related products and appreciate all the effort and time that goes into them. You are creating a forum for discussion about these products and deeper learning of them...good on ya mate! Cheers, John ;)
I have been toying with making this video for a long time. I knew it would be at my own peril but what the heck. Also when I was making this video, my target audience was my mother - who has no clue at all about batteries but has found her way into the cordless yard tool isle and made some very poor decisions. Like my mom, their are so many people who have no idea about volts or Ah and how it relates to tool performance - this is the purpose of this video to explain those numbers in the simplest way possible.
Like you mentioned, anyone who has a better way to explain these numbers to my mom - by all means - lets hear what you have to say.
Ok then, now I see where you are coming from ;) Bless you heart for helping your mom with her cordless power tool decisions. I hope she doesn't get turned off battery power and learns from your examples as well as others out there. Keep putting up the good fight Andrew! Cheers, John ;)
Got to take care of granny
Your math is correct, they cut the battery at 20% to save the battery. So you actually proved Ryobi is honest with their AH.
That is something to consider
cordless lapel mic will help your sound
I have a couple 1.5 Ah batteries and want to get a small 8in chainsaw. Not sure 1.5 will be enough
You did a great job on these battery review. I was curious about amp draw. I thought the tool itself would have a watt rating and this would give you amp draw? Anyway back to my original thought... when you buy into a system like this you are stuck in that platform. I would not be interested in another platform with more batteries and chargers sitting in my garage eating up space. I would just look into buying another battery to get longer run time. Plus the great thing about ryobi is myriad of tools in their arsenal. I don't think any other company competes with ryobi's tool diversity.
One more thing those batteries are new out of the package, are you not suppose to cycle them a few times to get best performance?
For most home owners, Ryobi is fine. No need to exercise lithium batteries - Charge them and go.
i just bought a ryobi lawn mower with an 18v 4Ah battery. gave it its first charge, which took about 2 hours. drained it in about 20 minutes
Yeah - that's ryobi for ya
Go check out the EGO on my channel
I have ryobi p271 drill driver. Does those batteries fit in p271. Looking for another battery
If it's any 18v Ryobi, then yes
@@Kitearmy is it worth having 6ah or 4ah for the money
@@2502860 go 4Ah and save some money
This comment comes 3 years after you made this video, so I have had many more YT videos to watch and learn about this stuff than you did when you filmed this and You seem like a smart guy so you probably have learned a lot since making this, so please don't think I'm being critical of you. I'm just trying to keep things accurate for the other folks that may run across this in these more recent times.
I have the same meter that you used in this video and it has to be zeroed when using the clamp amp meter. You started your first test with 1.1 amp showing on the meter, so you would want to subtract that from the current readings that you got during that particular test. That would lower it to 11.4 amps, and then go from there. A lithium ion battery's cell's AH rating is pretty much universally based on a .2 C discharge rate. For a tool battery, that would mean a 18 volt battery rated for 1.5 AH will provide 27 Watt Hours of power (18v X 1.5a) provided the tool only draws .2 X 1.5 amps or .3 amps. If the tool in question draws more than that, all bets are off. You may not get your full 27 WH. All you were monitoring was Time in your test. If you had been monitoring battery voltage and the amps going to the tool, which equates to the Power, you would have seen those did not stay constant. That's why the beach ball got closer and closer to the blower's nozzle. Basically you discharged that battery at about 34 times the current than it's AH rating is based on. If you had used a LED flashlight for your test the battery would have lasted much, much longer. I suspect that Ryobi, and other tool producers, offer different sized batteries so the battery fits the requirements of the tool to give a reasonable run time without excessive weight and unnecessary expense. I could be wrong though. At any rate, you got 22.3 WH out of a 27 WH battery, running it at 34 times it's rated value (if we ignore the obvious changes in voltage and current while the test was going on) That ain't too shabby, if you understand what's going on. Your 6AH battery has 108 WH of power in it, if you limit the draw to .2C. That's .2 X its capacity or 1/5 of its capacity, however you choose to look at it. That comes to 1.2 Amps. If you use it on a tool that draws more amps you won't get that full 108 WH. This 6 AH battery gave you about 83% of its capacity, even though you drove it at 9.5 times the Amps that was used when quantifying that rating.
Under high amperage loads the ryobi batteries overheat and the internal resistance of the cells decreases the voltage below the cutoff. The ratings are true but not under their intended use case. Every brand measures amp hours the same way. They use the number off of the battery cells inside the pack. Battery technology is very interesting.
Sure is interesting and these batteries are getting better every year
@@Kitearmy indeed they are. I just bought 2 used ryobi 4 ah batterys and a Chinese 6 ah. They were so cheap I just figured I had to have both. Lol. Its amazing how good even the used batteries are compared to ni-cd. The newer lithium technologies are so much more reliable than the old ones. The lithium rc batteries I used to run only lasted 50 or so cycles but now these new batterys last so many cycles I stopped counting. Battery tech has come such a long way in the last 5 years.
@@inoahmann7542 Its things like super capacitors that are really exciting - no energy loss
Okay here is my concern I got Ryobi string trimmer, hedge trimmer, and leaf blower all using the 40 volt battery. I am within the 90 day no question asked return period, while I like the tools and they work for me if the batteries are crap I don't need the grief. Should I return them and get some other brand. If so which? Milwaukee has a special string trimmer and blower package that looks good too.
Of course it depends on your needs - the Milwaukee system is a much better option but it is still an 18volt platform. Check out this review - ruclips.net/video/bswCWVuvzJs/видео.html
I'll tell you as a person who just checked in their ryobi 40v blower to a repair shop, and tell you what they told me when I asked about how good they are - they said they aren't the best, and they aren't the worst. You'll get a good value for your money. If it works for you, keep it. The trigger on mine broke but I'm sure it isn't junk and has a 5 year warranty.
And if you want the battery to last way longer, never charge it to 100%, and never drain it fully.
Personally I think EGO got the batteries right like no one else, but currently, their mower vs. ryobi's is $250 vs $400. You get what you pay for. I'll keep my Ryobi blower but if I have more money will go to EGO since they just got better and a little cheaper since 2016.
Course, EGO still can't bother with a proper battery gauge grumble grumble...
Oh and just to add, Ryobi has kept the same 18v system for decades, while improving the batteries to li ion and upping the amp hour capacities. They have over a 100 tools that use them. You have to give them credit for that system. It's very consumer friendly as you can still use old blue tools even today with new batteries. Their 40v setup doesn't appear though to have the same headroom as EGO's 56v setup, where 2.5,5,7.5 represent 1,2,3 banks of 56v power. Their 40v 5ah battery just stinks compared to EGO's.
Dewalt Flexvolt is your friend.Ryobi is long known for being for amateur use...and shit
I agree - This experience always reminds me that you get what you pay for.
Ryobi is underrated. I get sick of people low rating their tools like they are for amateurs. I'm pretty picky and I think Ryobi can handle big jobs. I've broke off bolt heads with Ryobi when I was taking it easy. Milwaukee is better, but I have never wished I went with Milwaukee instead of Ryobi. Also Ryobi batteries last way longer than I expected.
Is this a paid or sponsored review???
good vid, but I think you did one thing wrong you should be putting the model # for each part tested.
Thanks - great tip
