BAK 18650 2500mAh 20A Battery (N18650CNP)

I checked these batteries fresh out of the box. With no chargeing from me, every one of thes cells registared 3.56+v and 2468+mAh⭐⭐⭐⭐⭐ I have no doubt these cells charge up to 4.2v max and hold a nominal 3.6v as advertised,,, well, + or - .05v or so.... They weigh about 45g! These cells are THE REAL DEAL!!!⭐⭐⭐⭐⭐ ALSO,,, Customer care was VERY RESPONSIVE, answering logistics questions accurately and in short order.⭐⭐⭐⭐⭐ So what about logistics?⭐⭐⭐⭐⭐ & for good measure... I revieved my new cells nicely boxed and sepperated in,,, wait for it,,,,, 6 days from order I think your order will take close to the same or less if in continental USA. The Battery Store ships from, Gorgia I believe, (S.E. coast anyway) and I live 1.5hrs N. of San Diego, Ca. Honestly, I have NEVER had such a competively priced 18650 cell purchase be so trouble free, with such good product and customer care! I recieved quick and on time delivery of accurately advertised, new, quality high performance 18650 cells with real good customer service and timely, to the point and complete answers by email ⭐⭐⭐⭐⭐& After my (not so great) experiences with other li-ion cell suppliers, The Battery Store is a "Stand Alone" example to all others.

They see great batteries

Great Batteries!

The battery worked for what it was needed for and I’m super happy.

Bought 2 sets of 4 batteries for power banks. Couldn’t be happier !

Great quality batteries! Super fast shipping! Thanks!

These batteries work the same or better than the Samsungs these replaced. For the price, you can't go wrong.

the reason i bought these betteries was because the previous ones that i had bought were fakes and they werent lasting as long as they should be. the person said they were 9800mah but they were only lasting for about 20minutes on my unit so i did some research and found out i was scammed. so i went with the quality and dumped some money into new ones and here the batteries took some time to arrive and i have been using a trickler charger to charge them up. it took about 6 hours to get them up to 4.2volts but they both arrived at a voltage of 3.6volts exactly. i was impressed with the packaging and the quality. and im still running tests on my new battery pack i have built for my unit. These battery were made for high demand and boy are they holding up. i think i may buy more.

Work great in my mini backup. Very surprised by the price! Pleasantly of course as I have fallen victim to the knockoff type. These are genuine.

This reseller delivered the products very expeditiously. Amazon would have taken over 3 weeks but this company delivered in less than one week.

All good so far. Well satisfied.

Batteries came fast, worked perfectly!! Getting ready to order more!!!

These batteries are the right price they are the real deal they are 25 Mah batteries and they check out at 26 mAh very pleased will buy

So hard to find these batteries in store. Glad I found them online shipping was super fast!

Holds charges very well

They were here quickly & they work amazing I am actually going to purchase more this week.

They are batteries they charge and fit. They hold a good charge (they last a good long while) They are cheap. I ordered them Saturday night they arrived Tuesday morning

I'm really impressed with these Batteries and The Company I purchased them from...Thanks for the Fast Shipping and Quality of these items..!!

I received my batteries in an adequate time frame and they fit my Aegis vape mod perfectly. The charge seems to be lasting a little longer than other batteries I’ve tried. Besides, these batteries come 2 to a plastic box so when I travel or go fishing, I can put 2 fresh batteries in my pouch and not worry they might short out on something.

I bought 4 of these BAK 2500mAH 30A batteries to use in my high lumen flashlight and camp lights. Here is my initial tests of the batteries. I am using a postal scale with a .1 gram accuracy for the weight, a SkyRC MC3000 for the battery tests, and an inexpensive Tenma voltmeter for the initial voltage. Battery #1 had an initial voltage of 3.588 volts. Internal Resistance measured by the MC3000 was 24 miliohms. I did a Charge/ Discharge / Charge test to find the capacity from the factory. I charged at 1 Amp to a 100 mV cutoff... pretty standard charge... and discharged at 1 Amp to 3.0 volts. This may have lowered the initial capacity a little but it's better on battery longevity than going to a 2.5 volt cutoff. There was a 30 minute rest from charge to discharge and a 1 hour rest from discharge to charge in the cycle. The room temp was 82 degrees. The battery discharged 2350 mA from full to 3 volts and charged 2358 mA from that 3 volts cut off to 4.2 volts with that 100 mA current cutoff. The weight after fully charging was 45.9 grams. All following batteries were tested the same. Battery #2: Initial Voltage = 3.590 volts Internal Resistance = 26 miliohms Discharge after initial charge to full and rest = 2347 mA Charge to full after discharge and rest = 2369 mA Weight fully charged = 45.7 grams Battery #3: Initial Voltage = 3.590 volts Internal Resistance = 28 miliohms Discharge after initial charge to full and rest = 2349 mA Charge to full after discharge and rest = 2354 mA Weight fully charged = 46.1 grams Battery #4: Initial Voltage = 3.537 volts Internal Resistance = 41 miliohms Discharge after initial charge to full and rest = 2362 mA Charge to full after discharge and rest = 2382 mA Weight fully charged = 45.9 grams Final thoughts. For the price, these show decent weight and reasonable performance in the initial cycle test. That battery #4 Internal Resistance reading has since shown lower. The MC3000 sometimes has issues with flat tops getting good solid connections. I don't have the necessary equipment to test a high current draw temperature test, but I have used them several times in my Vaporizer and they stay pretty cool to the touch. From these admittedly limited tests, I would recommend these batteries. I think that the 2500 mA rating might be a bit of a stretch in real world applications, but the battery will deliver a solid 2200 mA performance under a decent load current for sure. That's not too shabby for a Chinese battery IMHO. Now whether it's got the life cycles to go the distance.... only time will tell on that. I only wish they had the same battery and pricing in a button top. Don't need protected, just a standard 18650 size good inexpensive button top please... Battery #2: Initial voltage =

Great price and great quality!

Fast service

Cool batteries

Fantastic Batteries!! I am getting incredible life out of these! I am using them in a Geek Vape Aegis Mod which uses a single 18650 & running them consistently around 55 - 60 watts. The run time is fantastic!! They charge up rather quickly as well. Not to mention the excellent experience I have always had with 18650batterystore.com!!! They ship fast and always deliver exactly what I order. I have zero concerns with the authenticity when ordering from them. This is my 3rd or 4th purchase from them over several years and I won't even consider looking anywhere else for all of my battery needs!! They always have exactly what I need in stock at an excellent price!! THANK YOU 18650batterystore.com!!! You Guys Rock!!

works great

Batteries last much longer than my last set. Highly recommend

I haven't tested rated capacity but these batteries work very well and seem to last a long time. Great value!

Super fast shipping work great with my vape and last long!

Used in Makita battery pack, worked great.

Great batteries and they threw in a free flashlight

Great device...customer service was amazing!

I love these for my vape! They work great and last a long time! Whenever these go on sale I grab me some more! I highly recommend these.

I bought these as a replacement for my Eufy Robovac 11+ as they don’t sell packs for these any longer. Original on the left, purchased cells on the right. Although not the preferred method, I managed to solder them together with the original PCB. Stuffed it back in the Robovac, charged it up and it works great! Runs at least as long as when it was brand new. Cells were well packaged and the free flashlight was a nice bonus.

Bought these batteries (4 total) just because they were cheap and had decent reviews, but these things are amazing! Been running 2 sets of ohm life's and these hit a lot better than those more expensive ones. They're a little less rated, but I can not tell at all. I think these are better over all. They don't last quite as long as those others, but not enough to matter. Will definitely buy these again.

These batteries work perfectly with my vaping device. I’m 59 years old and broke my back after lifting my couch, not been able to go to a store etc… I kept ordering the wrong battery size, I finally got it right and everything is working properly, so I’m a happy customer!!!! Thank you

Fast shipping, great prices. Will use for all my lithium battery needs.

These batteries are great so far ! I usually change batteries after 8 hours of vaping ( regulated mod at 55 watts. So far these have lasted 36 hours of use before changing. My usual battery of choice are Samsung 25R, which don't get me wrong are very stable and dependable batteries. But for a battery that I never heard of ? Thumbs up !!!!!!!

Great product shipping and arrival perfect will do business again and again thanks for a job well done.

Batteries work excellent. Batteries charge quickly and last several hours with frequent use. Very pleased overall with product and shipping. Thanks.

These are fine. I'm using them for low-wattage vaping. I'm skeptical of the 3000 mah rating and the 30a was always a fantasy.

Works fine.

Good quality cells for the price.

They came before the vape I had bought from another store, fit and work great, and a complimentary flashlight. 5 out of 5 would buy again

Batteries arrived in nice cases, and since I selected USPS shipping, I got a free 18650 flashlight!

So far half of the batteries are 70% dead.

needed battery for door bell video camera....up and running in no time...

Awesome

Decent battery for the price, holds a good charge. Not sure that they're truly 30a batteries(I haven't bench tested to prove)but for 3 dollars a piece they're worth every penny

Great product and I got a nice freebie I built a nice custom extended battery pack for my ryobi lawnmower and it performs great. Will be purchasing more in the near future for a few more projects

Batteries worked as needed. Delivery was fast.

I don't buy batteries anywhere else. 18650BatteryStore sells the real deal. Super fast delivery and the best prices around bar none.

Powers my crown 4 tank with no issues. Decent capacity almost a full day of usage.

The quality of the batteries that I ordered are Great.....have ordered other batteries and the quality was lacking, but these are exactly what I was looking for.

Quick, on time delivery and love the flash light!

Very good batteries for vaping hold a good charge and last a long time and reasonably priced

These batteries are my new favorite. My old vtc5s took a dump and i wasn't sure about these but holy crap these things are amazing! Great battery life and they deliver the power. Vaped my cloud beast king at 177w-250w and its just chucking clouds, instant power no ramp up! I honestly can't believe the price and wouldn't have if i didnt try em myself.

I found it more fulfilling to make your own 20v 5ah battery for cordless tools by purchasing 10x 3.7v 2500mah and aftermarket battery case and electronics. Really scratched that tinkering itch. Shopping for the batteries was superb on 18650batterystore.com. Highly recommend them due to their fast shipping and excellent product. All batteries are new and at stated amperage. Thank you!

Good long lasting batteries. Very pleased with them. Would purchase again.

I'm a repeat customer. Thed delivery time of the batteries is always reasonable. The best part of all is that these vape batteries work.

awesome shipping! Batteries working great!

Excellent

Good batteries at a good price. I will return to the site for my next purchase.

These Inexpensive batteries proved to be up to par

These batteries are perfect for my ecig. Hold a great charge! Would definitely recommend

Works super good and makes huge clouds

seem to work fine and hold charge with plenty of power

Great service, great price and FAST delivery!!

These seem to work as good as any.

These are backup batteries for when my others fail completely so it may be a while. I have both the green and red versions in service.

Great batteries, they came in battery cases too.

Tested these cells. They can handle my high-current draw flashlight with no problem. Usually, my flashlight would draw down from max brightness within 30 seconds on my laptop Panasonic cells. These ones stayed at max brightness until the flashlight got too hot to touch, which I had to manually turn it off. Also, I tested the capacity of these cells. I got between 2535 to 2670mah per cell. They're worth $2.99 for sure.

Used these 18650’s to replace the batteries in my Ridgid power tool battery pack. A little soldering was required to re-attach the straps. They work perfect for a fraction of the cost per battery pack.

used 49 cells to build a 24v 17.5 ah battery pack. Seems to be working fine.

Just what I needed. Delivery was fast. Battery's preform better than the previous ones I have used. I will be ordering more when the time comes.

All batteries were at 3.6 volts exactly and shipped very well.

All batteries were at 3.6 volts exactly and shipped well.

Best bang for the buck, this is the only battery store I can trust. Unlike Amazon, it's not buyer beware, these guys only sell quality batteries, with peice of mind.

Keep good charge

Best value on quality batteries that I have found anywhere. I highly recommend.

Packed extremely well

Great customer service easy to order

Both batteries(ordered 2) exceeded their rated capacity. Under high current loads these cells heated up less than some other cells I've tried. Great for high current loads! Will be interesting to see how they hold up to the cycle life

Work just as well as the expensive Samsung batteries!
