EBL 3.7V Li-ion Rechargeable Batteries 3000mAh 18J Rechargeable USB Lithium Battery for Flashlights, Headlamps, Doorbells, RC Cars (2 Pack)

I am writing this review to help out my fellow Amazonians whose reviews always help me and save me lots of time.So I have these two rechargeable flashlights I got from Amazon:“Rechargeable Flashlight, Magnetic Flashlight（included Battery), Super Bright Pocket-Sized COB Work Light T6 LED Torch with Clip, Zoomable, Water Resistant, 4 Modes for Camping Hiking 2 Pack”I would give you the ISIN number to be more helpful, but it looks like they discontinued this item so I can’t look it up for you anymore…but I think I can still give you some useful tips from my experience.So these flashlights are really awesome and I want to keep using them, but the original 18650 batteries died after only very light usage over 2.5 years, so I wanted to replace just the batteries with something higher quality.I’ve been using AA, AAA and D cell EBL batteries in other applications for many years and I’ve come to depend on their legit quality and dependability. So when I wasted a lot of time trying to find a 18650 battery I liked and couldn’t find any (because they seemed too pricey for unknown quality or iffy reviews ), I searched for EBL brand 18650 batteries.I couldn’t find any EBLs in this size, but I did come across these 18J size EBL cells. Knowing that these would be slightly bigger than the original 18650s, I unscrewed the end cap off my flashlight battery compartment and eyeballed the interior of the tube. In terms of width, there was definitely some wiggle room for the original 18650 battery to move side to side a noticeable amount, and in terms of length, the spring tensioner in the end cap had plenty of give, so I took a chance hoping these wider and longer EBL 18J batteries would fit and ordered them.Low and behold, they fit perfectly fine, replacing the smaller original 18650 batteries, and I found the EBLs to be notably heavier and much higher quality than the originals (as I have come to expect from EBL). They are also rated to last much longer per charge which is a nice bonus upgrade for my flashlights.I’m very satisfied with my purchase, and very happy I get to keep using these nice flashlights with these high quality long lasting batteries from my preferred battery maker.I hope this info can help out a few folks who find themselves in the same boat as I was! Cheers

We really like the ease of re-charging without bulky cases to plug into the wall outlet. Charges last quite a while. The battery storage cases are nice.

My mom is visually impaired. She uses a flashlight to read. I bought these to use in her lights and they worked great the first two charges. I received them the end of Nov. Now it is early March and they don’t hold a charge more than one day EVEN WITHOUT BEING TURNED ON. I thought they would work better than the cheap ones, but they are even worse. Very disappointed.UPDATE: After I wrote my first review the company contacted me and sent replacements for the bad batteries. I charged them and the new ones didn’t work any better. The company reached out to me to see if I was satisfied with the replacements, and I told them that I must somehow be doing something wrong since I couldn’t get them to hold a charge. They just contacted me and say they have processed a refund - totally unbidden by me. THE CUSTOMER SERVICE HAS BEEN EXCELLENT AND FAR EXCEEDS MY EXPECTATIONS. Because of that I am changing my overall rating from 2 to 4. I may not have gotten the results I originally wanted (long lasting batteries for Mom’s flashlights), but the company made sure that I was not penalized for it.

This 2-pack of batteries works well for my usage. I use them in small Gearlight flashlights. These are spec'ed to use 18650 rechargeable 3.7V batteries. These EBL batteries fit in my flashlight fine. They are technically slightly longer than 18650 batteries. However, my flashlights (and most) have springs which hold the battery in securely at the bottom, which allows a small amount of variation in size. The battery fits fine w/o any issue whatsoever (no difficulty screwing the bottom cap back on the flashlight). The battery life seems as expected. The one item that makes these batteries better than most is that they have a micro-USB input on the battery itself to allow charging. You do NOT need a special charger to charge these batteries as has been required with my past 18650 rechargeable batteries. The only improvement I would like is a USB-C input instead of micro-USB because most of my devices now come with USB-C (more modern). However, I have tons of micro-USB cables since that was the standard just a few years ago. Perfect purchase for those needing 18650 batteries as long as your use allows a slight length increase (see the length specifications) from a standard 18650 battery (which most flashlights at least allow).

Perfect for my work light.long charge time
