Thanks for making this video and learning us about 18650 batteries. The first time i came across 18650 batteries was when i was vaping. I saw many 18650 batteries with flat button tops and batteries with button top some of my vape devices pushed the button top inside the battery which damaged the battery untill i could not charge them properly. So now i know there are two types of 18650 batteries. The last buttontop 18650 battery i purchased is the Ansmann 18650 with 3350 mAh for my XHDATA D808 radio. It came with a 2000 mAh XHDATA battery but i replaced it with a Ansmann 18650 mAh 3350mAh one so that i could listen to my radio longer without USB-C charging! Thanks for sharing Tenergy Official!
Great video. You dont speed or mumble but talk clearly. Thats me attended your classroom. I walked in knowing nothing and came out knowing everything. Brilliant!
Such an awesome video, equivalente of hours of research. Easy to understand too! Thank you!
One of the more informative battery videos I've seen. Thanks!
Thankyou!!! Today, I learned something new!
Pertinent Info delivered efficiently & professionally. 👍🏼
Wow! Great! Thanks! So intelligently put together and diligently researched! and pertinent. Thanks again!
Thankyou very much for this video. Really informative and well done.
Thank you. Very helpful and informative video
thanks, great video, took me from knowing nothing about these batteries to having pretty good overall understanding. Perhaps beyond the scope of an introductory video but I would be interested in how to link the batteries and use them in devices that need higher voltage than 3.6V.
Thanks for the information 👍
Ok - video starts with explanation of the name - all I need to respect and subscribe!
Excellent video. Thank you.
Really great explanation video 👍
Thanks for the great explaining video
Thank you, great video!
Very informative.
New into devices with 18650 batteries, thanks
Great informative video! 👍
Gee this is one video I should of watched before buying rechargeable batteries ! Lesson learnt .
Woah. Thank you!
It's so hard to find a Legit 18650, and the most legit ones I've seen are like 50x the cost of the fake ones. I've seen some cheap ones that may actually be legit like Samsung INRs
If you don’t want to pay for new ones you can salvage them from old laptop battery packs and they usually work pretty well
Try at a vape shop they typically sell them for about $10 each and always are legit
I had to look far to find one on eBay 😅So worth it though if you can find 'em. Pretty nifty piece of tech
Panasonic / Sanyo (red sleeve) 18650 and 20700 cells are legit.
Thanks 👍
One question is there anyway the lithium oin battery's still good cuz of the bms being fried and it made all the batteries to .013 percent now ? Do you know if u think i can save them batterys ? There still good no physical damage to the batterys
what material is the tabs made of. the negative and positive tabs.
Should have included here when talking about capacity the scams, and clearly state any battery claiming to be more than 3500/3600mAh is a scam.
And a mention on the weight, high density batteries (3000-3600mAh) tend to weigh 45g up to about 48g.
Some of the batteries on Amazon and eBay state capacities of 9000mAH and 9999mAh - these are SCAMS.
Bravo, very good info but it is still tough to determine the differences in the what you call PCB cell versions (BMS internal circuitry) to those without. We are still in the Wild West when it comes to specs and capacity is a gamble with so much exaggeration. You almost have to get sample cells and test them for capacity. I got off on the 26650 cells and find that most have less capacity than the 18650 cells plus the Hype about capacity say that some are 12,000 mAh when they are ! 1000 mAh. Are there vendors that fully states the true capacities and whether they are raw cells or PCB type cells? Thank You.
Great video! Is there a way to tell by looking at the battery if it has the protective circuit built in?
Typically with a Tenergy battery you'll see an extra ridge at the bottom of the battery, otherwise it's best check with the battery's manufacturer. If it's a Tenergy 18650 battery please reach out to us at service@tenergy.com with a photo and we can help confirm.
Can I use the normal 18650 batteries on diy Powerbank Case
I still have my Convoy Flashlights I purchased 2017 and 2* Panasonic and 2* LG 18650 batteries.. 😀
Lot of people aske me about my flashlight because it is so bright..
@Tenergy Official Thanks for the video. At 2.17, you showed table for maximum discharge current. How long can these batteries supply maximum current safely in seconds? What are the maximum safe continous current for these batteries? Thanks
Hi Adeyemi, the chart outlines the max discharge current for each battery, these are safe levels. To find the runtime at this rate, you can divide the max discharge rate by the batteries' capacity. The chart already outlines the safe max discharge current for each battery. If you have more questions feel free to reach out to us at service@tenergy.com.
@@TheTenergybattery If a battery has 2600mah and 5.2A as maximum current. Duration (assuming 100%discharge)=2.6AHr/5.2A=0.5Hr=30minutes. This may not be practically correct as the battery may not be able to supply 5.2A continuously
I have just got a 1000 lumen torch that has a LX-BAT-2600mah (LGlhon battery) could I use a visvic li-ion 5200 Mah battery in it?
Can I charge li-ion batteries with pcb using tp4056 it will safely than batteries without pcb , specially I built home emergency lights
Please recommend a small solar charger, headlamp, and small flashlight for backpacking.
I have a power bank which is not working right now..i opened it so there are 3 batteries ( XHK18650 19C25-A1 3.7V) AS Per device configuration capacity : 6000mAh (22.2Wh). if i want to replace the same with new one so which one i need to take. can you suggest ??
Can I leave the battery in my flashlight and charge through the flashlight or I need a battery charger?
Thanks for the helpful Vid. A question, I have cheap Ebay head torches that came with Cheap 18650 rechargeables. If I were to replace with better quality 18650s shoud I still use the Torch's inbuilt charger to charge the new 18650s?
Hi Fussybugger, the charger should work fine if the new battery is the same chemistry and voltage. If you're unsure, please contact the battery manufacturer to confirm the battery's charging characteristics. If it's a Tenergy battery, please reach out to our team at service@tenergy.com and we can help confirm compatibility.
Nice👏👏👍👍👍
Why anything over 1000mah is not simply marker in AH is odd, 2600mah is 2.6AH
I have a mosquito swatter that uses a 1200 mAh 18650 and deploys 6 UV LEDs for an Automatic mode that drains the battery approximately in 30 minutes. Hence one has to keep an USB charger connected to it for a continuous duty (say, overnight) in the Automatic (UV) mode. The battery is intended to be charged with a 5V, 1A DC input. Can Fast Charger ruin such batteries? Can I use any multiport USB wall charger that outputs 1A as charging current for this device? Does a 2A charging current harm the battery?
How do you check remaining charge in a 18650. I have a multimeter, and can see a voltage of 3.7 or so. But how do you determine how close you are to the voltage dropping enough to stop working?
For Li-ion batteries, when the voltage gets around 2.8-3.0V, the batteries need to be recharged.
Hi, can you determine the % capacity remaining from the voltage? If the range is say 3.7 to 2.8, is half way between 50% depleted, or is it non-linear?
@@vexy1987 it’s mostly linear and 3.7 is ~50%
How can I test its capacity? And where could I buy the battery’s cheap but not fake mah ratings ?
I have a Aiwit v5 video doorbell. Any idea what best batteries / specification I need?
Hi Ian, please reach out to our team at service@tenergy.com with photos of your current battery, and we can help you match it with a replacement.
I bought new 18650 flat head batteries for my flashlight but on the picture of how the batteries go on the flash light the batteries have nipples. Does this matter? Cuz it don't work with flat head
Can you get a higher capacity?
PCB stands for printed circuit board not protective circuit board.
My mans took me to school. #kudos.
End of line.
What about 4200 mah? 4.2 volt li lion what can i substitute? Since i cant find one anywhere.
Hi Joe Shmo, please reach out to our team at service@tenergy.com and we can help you find a compatible battery.
Nice
Okay, but doesn't flashlights have their own protection against temperature and low voltage?
How long does it take to charge a 18650 lithium battery?
i think around 1 hour and 30 mins or 4 hours
Good video, but I am still tortured trying to buy replacement cells for my camera gimbal. The factory batteries are garbage and don't last, but the fit is critical and everything I have ordered online is a hair too short to fit. The factory batteries are flat top, but the flat top protrudes and the batteries stack inside the handle. Everything I buy seems the same length, but falls out of the gimbal's handle, which is side loading, not end loading like a flashlight.
HI Danny, if you like you, can reach out to our team at service@tenergy.com and we'd be happy to take a look at which 18650 battery would be a better fit your device.
Is it normal for the battery to feel slightly warm when charging? For example, I have Sony VTC6 3000mAh 18650 batteries being charged with a Liitokala Lii-600 charger, and the charging current is set to 2.5A. The batteries feel slightly warm during charging, and this happens with all the authentic Sony VTC6 batteries I have (10 batteries). Is this normal? What is the normal temperature during charging?
Greetings Karanzaberni, it's normal for batteries to get warm while charging. For your Sony VTC6 18650 battery, it can reach 140°F during charging and still be within normal range (we suggest confirming with Sony for the battery's specifications).
@@TheTenergybattery Well, at least now I know that my battery and charger are still good. If I don't know the standard temperature for charging, it could potentially shorten the battery's lifespan or even damage it quickly.,
Good
If it is 18 x 65 mm then what is the 0 for?
0 means cylinder, reference to the shape.
yeah good
What's the minimum voltage for a 3400 mAh battery that's considered fully discharged?
Hi Joey. Typically 2.8-3.0V, but there are exceptions, so the best thing is to check with the cell's manufacturer to confirm your specific battery's minimum voltage.
@@TheTenergybattery thank you for your reply.
The discharge protection circuit is set to 2.5 volts on my Nitecore "NL1834" 3400mAh battery.
Is it SAFE for the battery to discharge to 2.5 volts without it harshly effecting battery life?
Are there any 3000 mah that are smaller sized than the 18650?
I don't think so, 14500 is the same sized as AA batteries, but they are usually only 900mAh
"PCB" 😂😂😂 3:00
tell me how manufacture's can cram 9900mah in the same container as a 3400mah those are fake 18650 and the weight on 9900 mah(34g) is lower than 3400mah(46g)
They cannot no 18650 battery can be over 3400mah and no battery can have a higher cdr than 30a
The ones that say 9900mah are typically fakes with a very low cdr and a capacity less than 2000mah you get what you pay for most of the time
So the ones marketed as having 9900mah are? Bogus? Inflated? If the max is 3500mah,how can they have 9900mah?
More videos like this plz!!! Sub'd
Everybody put emphasis on only one thing: capacity in mAh as if it's all that matters, smh. There are low drain devices and high drain ones, those two factors will determine what battery is right for you, bigger mAh doesn't always mean all as higher mAh ratings usually come at a cost of CDR continuous discharge current compared to the lower mAh ones.
hi sir I have samsung LG battery
Most button top has pcb?
Wait what!? The bigger ones are safer then the flat ones?? I tought the flat ones had a fuse for safety and the tall ones had nothing.
That's right. Generally button top 18560 batteries will include a protection circuit board with them, whereas flat top 18650 batteries are used for battery pack making and the PCB can be added to the battery pack.
Did he just say protection circuit board? Lol
This was actually helpful as fuck!!
Thank you
That wasn't all I need to know
NO MUSIC PLEASE !!!!!!!!!
Yeah let's talk about fake power rating on Chinese 18650 batteries !!
i know im just being a hater, but honestly I had flashbacks of having to watch a class full of 3rd graders read their book reports watching this. Buddy is reading this script like hes at the science fair.
Tested 10 cells (18650) have a capacity between 1500 - 1700mAh out of the advertised 3500mAh. Underwhelming product claimed as being Original 18650 HG2 3500mAh - brown sleeved. _A v o i d: ->Sh op1103577373 Sto re
