EBL3.7V Li-ion Rechargeable Batteries 3000mAh 18J Rechargeable USB Lithium Battery for Flashlights, Headlamps, Doorbells, RC Cars (2 Pack)

Recomendable

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

Bought these to replace the stock batteries in some portable shop lights that would no longer hold much off a charge. Chose this brand for capacity and easy USB recharge part on battery. Batteries worked great. After 6 months one would no longer hold a charge and the company replaced it, no questions asked, very quickly. I would absolutely buy these batteries again.

These are good batteries. They hold a charge for much longer than I expected. No clues as to how long they actually run at full output levels but I think they are a great replacement for my flashlights. They take a long while to charge but that's pretty normal. I have a 10,000 a 4,000 and a 600 lumen flashlight that I carry on the job and these EBL 3.7V Li-ion Rechargeable Batteries are great in them all.They are longer than the average battery in their range to accommodate their charging ports and will not fit into most side loading compartments, such as the one in the photo from my headlamp, but they'll fit in every flashlight cylinder I've dropped them in. I'd guess a doorbell would not be a good fit for these either but I've been wrong before.After a year and 5 months mine are still going strong on my Stache 5 mount, my helmet mount and my handheld torches. Looks like they're $1 cheaper now too so I recommend you grab a set...

So far, they are working fine and seem to hold a charge for a long period of time.
