Lithium Ion battery Fix #1 Ft. Tool Girl Hana
HTML-код
- Опубликовано: 12 сен 2024
- As many of you all know, I use an 18v Rechargeable Makita drill & and angle grinder.
Unfortunately, the last of the 4 battery packs stopped working the other day leaving me without the use of either of the very useful tools, the drill I needed to complete a honing task on the Honda Magna engine that I'm fixing up at the moment.
So.....like many of us would in my situation, I stumped up the $260 for a couple of new 3.0 amp hour 18v genuine Makita batteries....ouch!
But.....shortly after a viewer commented that it may be possible to bring the old batteries back to life & he sent me some instructions....bloody perfect I thought, we must give that a go!
I did a little more research & found that there are quite a few different methods kicking around RUclips for this fix so I decided, since I have 4 dead batteries, to give a few of them a go & see which one seems to work the best (most successful so to speak).
This video covers the first & probably the most comprehensive option of bringing a Lithium Ion battery back to life. The instructions were clear & really explained the problem that is occurring inside the battery & how the 'fix' overcomes this...
In this video I cover the first of 4 methods so there will be at least another 3 videos on this subject, covering Fix #2, Fix #3 & Fix #4...
I'm hoping that one or two of you will find this Series of videos interesting & helpful towards you bringing your batteries back to life.

I totally don't remember anything about this video except Hana 😍
I don't even own a screwdriver, but I love this channel.
I want to say I clicked on this video to learn something, but that would be a lie. The thumbnail got me. I'm a sucker for a little bit of skin. Well done Hana!!!
My partner has a lot of tools, so when he needed a circular saw, I ordered this one for him as a Christmas gift. ruclips.net/user/postUgkxYDKeIjKLOfcwTgdin7TtCutsz4MbIc43 He is incredibly happy with the purchase. He stated that he likes that it is powerful, but still easy to use and cuts very well. He mentioned that it is important to know the right tools for the job at hand, and this compact saw has been exactly what he needed for a variety of projects at his rental properties and renovations. He also appreciates the battery packs, as stated, he owns a lot of DEWALT tools, so he is able to always keep batteries charged as needed.
What were we talking about again? Sorry 😅
That Hanna has that gyrations really working on the wire!! I think by the looks of it i am fully charged! GOOD JOB HANNA!
Sweet Video, I am contemplating purchasing Vinco aftermarket replacement Miketa batteries for my aging 18 v. tools. Verry informative video epically @ 44:49- 50, 46:13, 47:53, and 57:17. Still un- decided on purchasing a battery but Hana could assist me.
If you have a solar charger plate, the unloaded voltage is much higher. Let it sit on a poor pack for a day, and try your charger afterwards. I can't say it always works but it did for me.
Thank you Andy I always love watching your wonderful videos I am from South Africa
Hana showed great initiative and curiosity when she put one of the new batteries on the charger to see how it would be read.
Hana doesn't take instruction he showed her how she should use the battery to rest on whilst doing this procedure but kept on doing it her way 😔
I enjoyed the show please don't stop thanks for letting me join thanks (Ross)
Good try I have been doing that often with normal rechargeables and regular batteries but for lithium it may kill the BMS battery management system
But auwsom guys you are great fun❤😂
Agreed Richard my eyes are red and watering,and my stare is 1,000mi.
You can always use a relay through the 30/87a terminals its buzzing is fun and is alot faster more dangerous and probably still won't work
Your better off swapping the cells around if you can get the battery open.
Flashing the faulty cell directly has limited short term success, but through all the cells less success, buy new if you don't want to spend time in your workshop with hana :-)
Lol!
Great channel Andy! Hana is the best! You two have the best on camera chemistry. Plus, I learn great tips! Thanks, from Georgia USA.
Such a lucky man. Hanna you are breath taking !!!!!
Hey Brother using a bus bar is actually the smartest way you can go I don't think it's stupid at all you're a good man
Hana looks great. Even better if she walked off and came back with alcoholic beverages or just some cold Dr.Peppers will do too.
And who cares if she drops anything and bends over to pick it up accidents happen.
the female helper is the only reason I would watch an hour long video........
Try jumping the new battery to the old battery to give it a bit of charge so it can be recognized by the charging unit itself
the best way to do what you are doing. is to DIRECTLY CONNECT 2 SAME LITHIUMS OF THE SAME VOLTAGE BUT ONE GOOD BATERY TO THE BAD! FOR ABOUT # 3 or 4 mins or more!
I build li-ion batteries please read up on lithium batteries and then Hopefully we won't be hearing about your house fire on the news .
13:00 you’re welcome
😂😂
New subscriber here. Even though it failed, you inspired me to try this at home. Btw, love your shirt, Andy. Keep up the great work.
Pretty sure she could charge my battery!😅😅😅
Have you tried battery number 1 in your drill it could be you've fried the circuit board in the charger has it has a failsafe it won't charge a battery if it's been tampered with.
There's only one more battery that's got problems a bit like yours Milwaukee the rest can be charged as long as there are no cells dead in the battery.
The old 'hand a girl a spanner' marketing method for channel promo.
Good on ya Hana for getting into the workshop mate.
I can't think of any shed that would get past the uniform & do any work though 😉
Up next... we do an oil change on a Llama & I bet we still increase our subscriber base 🤣🤣🤣
Lol!
I can't believe it took more than 40 freakin' minutes before you stopped disconnecting the negative battery lead and removing the razor blade in order to test the voltage with your meter probes. SMDH....Fortunately, Hana's sexiness kept me from switching off your video. This procedure has been used since NiCad batteries came to be. Other than that, I do enjoy your videos, Andy.
haha i just watched this entire video because of hana. shes great
40 mins in video love what Hana did
great video that shirt works well on hana,she wears it well. shame she isn't on channel anymore #1 tool girl for me.xxxx
Putting her on here with little to no clothes on was a great way2 achieve views... Breast wishes
Okay... first time seeing this. Won't be the last!
Thank you, Hana and Andy. Most experiments end in failure.
Cheers Peter, was fun trying and this is just the start of this investigation into these batteries...it's such a big issue I'm keen to learn more and see if there is a plausible way of bringing them back to life...
Thanks for your feedback. Cheers Andy
Peter Brown most thing's I attempt in life end in failure.
Good video, we all need to learn more about are cordless tool batteries. Your Female helper is a BIG help on seeing this video.
Dirty as the battery and the battery charger is. Might help to clean the contact points on both of them. Eraser and cotton swab,with rubbing alcohol. Works really good
هل عند تظيفها تعود للعمل بشكل جيد
In the In the beginning you were talking about Someone writing in And explaining The crystal whiskers that develop inside the cells I believe they were referring to Nickel cadmium And that's how they do those , And yeah The process there talking about Will work with those But that's not lithium ion Lithium ion are way different And quite dangerous That's why the bms had to be installed in the lithium batteries . If any lithium cell drops to or below 2 volts that bms opens the negative line to stop any charging , its a safety thing and if you open the battery or put test leads on the positive thermal and negative on one of the smaller cells you can actually see the voltage of each cell and 9 times out of 10 one or more cells have dropped below minimum so if you want to Magically "fix" the battery then maby you can balance charge each cell so all 5 in that 18v battery are at the same level
then put it on its charger and it should charge up fine ,that is unless the bms is bad as sometimes it needs replacement but for the safety of your readers please read up on the types of batteries before giving out wrong information.
Hey Andy, I checked the website and that's for NiCD batteries, not Lithium batteries. Also, Makita "18V" batteries are 5x 18650 cells, 3.6v nominal each cell, actual fully charged voltage is 21V.
The reason the charger isn't charging it is because the computer in the battery flagged the battery as defective. The cells themselves could be okay, but the battery management circuit will ID the battery as bad to the charger.
Hmmmmm.....interesting. I'll do a bit more digging. Cheers for the heads up. Andy
Hi Andy,, fixed my problem with my quadbike. Turned out it was a battery problem so i reconditioned and all is back to normal. Wasn't the ICV after all. Saw a dumb prick playing with his car and he said he thought the ECU wasn't getting gull voltage needed on startup like my quad. Mine starts instantly now and no funny tricks. Reconditioned battery with a CTEK XS7000 charger. 👍👍👍👍👍👍👍👍
Ah, great job Chris :-)
Andy you should fix the connector permanent for 6 seconds . Not just by rubbing for 6 seconds .
Rubbing it 6 sec works for some. Sad
Yes good teacher with her helper good lack
I'm pretty sure it's not the voltage across the main terminals that the charger is looking at when it determines whether the battery is too deeply discharged or faulty. Inside the pack, they have banks of 5 cells (more banks for more Ah) and there's a thin sensing wire between the negative and the first cells and the BM circuit board. So I expect it's looking for the voltage of the first cells, not the total.
Edit: Also 34:32 It's not fully charged at 18V. That's just the nominal voltage. Voltage doesn't change a lot except at the extreme ends of the full charged/fully discharged range for lithium batteries.
Maybe it’s worth opening the batteries up & checking wether all the cells are healthy & balanced before you go bypassing the BMS with 25 volts 🤷♂️
Hmmm....agreed, we do open up the battery packs in the next Episode...
Cheers Andy
You're a lucky man to have a very attractive assistant.
I didnt relize how old these videos are . Buga.
Lol
I need an assistant like your assistance...will make the day more enlightened...
it certainly does :-)
If it came up to 18 volts with flicking the wire on and off why didn't you then put the battery in the tool it comes from and try it? an 18 volt reading indicates that it is fully charged.
Great video!! I am very interested to see if these batteries can be saved. Replacements are ridiculously expensive. Also, at the beginning of the video when you touched the two leads of the series wired batteries together, did they get as hot as Hana?
They got crazy hot yes, but no way as hot as Hana! :-)
some of the battery's have a pcb inside that count the time i t has been charged and stop charging after a set amount of charges . dont know if the makita ones do . but you can also open the battery up and change the cells inside. you can also that the pcb out of the battery and put your own charging balancing board and drop protection in
Thanks Simon, yes, I agree we should take a look inside, good idea.
If that's true, that's terrible.
How about charging without the charger? Find the charge voltage and charge it using a PSU and you may be able to use it again.
Simon Rawle )
44:45 and 47:50 you're welcome.
we thank you! :))
I was like Yay, someone's pointing out where he talks about the actual problem/fix! Nope, boobies.
omg im glad im not the only one that was looking for a slip.
Carpenter's dream
how about instead you try 44:50, 46:13, 47:53, 49:41, 49:49 and particularly 57:11
I brought back a few of myu battery's that way!
You didn't try replacing the cells inside! You can make 1 or 2 good with 4 batteries !!
Hi, thanks for your comment. I give this a go on the next video. Cheers Andy
Battery boost up over 4-6 volts then plug in it will be working if good cells ...if using 24 volts to boost up , battery have BMS may stop working to protect over voltage...?
I wished I could find a tool girl like Hana for my channel.
I wish she'd tie the knot a lot higher
Makita batteries are known for having bad BMS boards in them. The batteries are probably fine inside, but the electronics that control the charge is bad.
Jon Marcelle y
This technique is for ni-mh or ni-cad batteries NOT lithium li-ion batteries. you need to re balance the cells in the battery pack for it to properly work again. theres loads of info about how to do this on the net. gota say though hana really lights up the show
20:36 the bogus negative wire pops up into frame. 20:38 Andy push's the neg wire not connected to anything back out of frame. Nicely Done! Love Hana though!
i have successfully done this with NiMH batteries for rc cars, by jumping the little dead battery with a larger good battery (both NiMH)
Hey would like to see more of Hana
How I agree! This is one of my favorite channels now!
Hana does a great job pulling those small baTTs out of the charger
Hana is pretty intelligent in my view.
The PCB inside has 'bricked' your battery. All it takes is about three attempts and it's 'bricked' forever. Fortunately, the PCB is about $5 or so.
yeah, chickaboo is not bored at all :)
Genius, batteries and a bird
Lol!
Hook up leads to a good battery, put on charger and attach the the other end of the leads to a bad battery... The good battery will trick the charger.. 😉
You said Fix. didn't fix anything! I want my hour back. 😎😎
connections should be TIGHT! Both on charging and testing.
Excellent !!!
Use a 25Amp bulb 💡
25 Amps @ 14v is a 350 watt bulb, that's really big!
@@AndyMechanic I just revived 4 out of 5 Dewalt batteries 10 minutes ago
Andy . I think you need to put together a calander that we can buy . ??????
I have them! $40 NZ plus postage if youd like one? :-)
44.10 love that shot of Hana lol another great video thanks.
I fix those batteries all the time and never buy new. Only the charger and its usually just $20 on amazon
put the batteries away im not hearing a thing as my eyes are blocking my ears.
never mind the batteries!!!
mate you need to open those up and replace the dead cells in them. They have a pcb board in them. They will take 18650 cells i would think. since you have three i would just sacrifice one too repair the others. You have have to check the voltage of the individual cells.
Hi Marcus, Thanks for the info. It's a steep learning curve on this topic but with all this excellent input I'm sure it will result in a great final video. Many thanks Andy
Wrap the multimeter rnds with some .031 safety wire this will allow you to make beter contact.
wonder how many times they pop out during a production
ok, 5 years ago but it showed up in my feed the most painful battery test I have ever seen. I can't access the document but for anyone watching good thing it did not explode. The minute I saw how fast the battery was losing voltage I knew there was a dead cell. THere is a Battery Management System (BMS) in the battery pack that tells the charger the voltage of each line of cells. So one of two things, either an individual cell was dead or the BMS was dead.
Correct, Thanks, it was a learning process & the rest of the Series covers bad cell identification, replacement & new BMS fitment too. Good info. Thanks again. Andy
or just go all-in and let the thing stay on for at least a few seconds
If you find your keys, why would you keep looking.... Hana is just a little hottie!!
She needs a push up bra to get some cleavage going! haha
Work in progress ;-)
Hana does not need a Bra how dare you suggest such a thing! It was bad enough when she got a shirt :)
Thanks I hate bras! I'm lucky that i have little perky boobs I dont need a bra😉
Really Hana? sorry I had not noticed I was too busy concentrating on what Andy was teaching us !!
And I don’t think using charged and shocked and hard and such words is very distracting . 😮
Hi Andy & Hana When you touch the connections the idea is to leave connected for a short period all the current is used up makeing the spark its current not voltage you are trying to put back ie charge.I have manage to recharge batteries that have been run down to low.
Hana great beauty wow, again I'll watch again for the project lol, love perkies
Tool girl Harley please. She is amazing
A bit flat 😂 I mean the battery 😆
Used the battery from the drill
Get a damn good multi meter
Or try 6 seconds of continuous contact each time
Hannah you're even beautiful in your glasses gosh I love you
more cider for hana
Just curious why you keep pulling the ground out and then try to jam the MM terminal in to make a circuit when you could just touch the ring terminal
never mind I seen you finally started doing it
When I individually test my batteries I get 4.00-4.05 volts per battery on 20v battery but when I test them all together Its 0.02? What’s wrong with it. My drill won’t work. It overheated when I was drilling a hole with a dull hole attachment
Lol is that ladi the shop's cocktail waitress, my god that outfit is hilarious
No it's perfect bob
I know you are not an authority on this circuit t install BUT I put one in and now the battery does no cycle back and forth on the green and red light BUT it keeps the overheat light on even after putting the battery in the freezer for an hour. I charged the pack when apart to 18 volt but still a no go on overheat light. any thoughts.
I'd guess the thermistor has failed, that's the little thing on the circuit board that hangs down and is encased in a white sealant in a hole on the internal black plastic moulding that mounts the circuit board. For the cost of it just replace the circuit board complete I'd say. Cheers Andy
Andy Mechanic this is on the new banggood board, I may try to clip the wire on the thermistor
Hmmmm. ..it seems odd, especially with the battery cold too. Could be a faulty circuit board as they make so many of them at such a low price. Let me know how you get on. Cheers Andy
This is crazy , most likely one cell is to low and the BMS has stopped the charger from charging to prevent over charging of the other cells . you are about to have a bad day. Please read up on lithium battery and learn what is really going on inside that battery.
Try jumping the new battery to the old battery to give it a bit of charge so it can be recognized by the charging unit itself
oh this video is ancient lol
With that many batteries, you could take each cell and find the bad ones.
Yep make 6 good ones
So what does Hannah look like now 5 years later? Check out the battery things and some of the comments were quite helpful. Kind of wonder why you don't have more subscribers. Are you got a lot more subscribers than I do, without a doubt. Here's an idea for you. I think it's 24 volt I'd have to check but seems like each brand for weed eaters and what-have-you have different voltage. They come with a battery charger that's easy to lose and it's gone. This. Over the winter ❄️. Building or modify a battery charger so you can dial-in the current looks like you do on a welder.
The PCB inside the battery will often 'brick' the battery....like if the battery was hot and put in the charger for three tries or more. Nothing to be done then except buy a new PCB and replace your old. When the old PCB 'bricks' the battery, it is forever with that original PCB.
Hi-de-hi Andy. your batteries are lithium.the instructions i sent where for ni cad. Ive never tried them.
Bummer....maybe that's another reason why it was unsuccessful. Work in progress! Cheers Andy
best to pull the pack out and test with your multimeter. if bad you might as well replace the circuit board
good
