Keeppower Protected 18350 Li-ion Rechargeable Battery Button Top 3.7V 1400mAh 5.18Wh for Flashlight (NOT High Drain) (2 Pack)

As good or better than the OEM that came with my flashlight.

I want to say thank you Chuck for highlighting this feature.. these fit the Wuben E7 like a custom glove. I was having trouble finding one that wouldn’t turn off when you shook it.Can’t wait to battle test them.

I work in the tactical firearms industry, and lights play a big role. And batteries play just as big role. Low quality batteries can render a top tier platform ineffective. These batteries have always given us great results. Normally it try to buy them in bulk, but in a pinch I get them from Amazon. Can’t go wrong with this brand.

Purchased these for a Radiomaster Zorro RC aircraft controller, which uses only 18350 batteries in its internal bays, but they are too long to fit between the contacts without breaking something. Not sure how a battery, built to a certain spec. cannot fit into a device built to hold batteries of that same specification. Wasted my money, I guess.

Charged without any problems. Installed in T1 flashlight. Fits good and works fine.

Bought it for my Nitecore EC11 (39mm) but the KP battery was longer than Nitecore's 18350 (37.2m). A work-around is to put a metal ring inside the top of the EC11 so the flashlight body cylinder could make contact to enable it to close the circuit loop.I chose the KP, over both the Nitecore (700mAh) & Efest(900mAh), due to it's higher capacity. I tested KP and both batteries came in at 1350+ mAh close enough to the 1400mAh advertised. I will test again at my next recharge and see if the capacity is consistent.March 2024 update.Battery died on me. Definitely have less than 50 full charge cycles since purchase of these batteries and it died on me. Changing my rating to 1 star because I expected them to last at least few hundred fully charged cycles before dying and it only lasted less than 50. While the initial mAh was good the durability was not.

Needed a 18350 button-top, high drain, battery. However, these were too long for the red/NIR torch I have. Refund given so satisfied but still looking for right size battery.

I received these keeppower 18350 1400mAh batteries yesterday and tested them. One was 1530mA and the other was 1380mA well within acceptable range for me. They are protected but still work in my sofirn IF19 & SP40. I tested them with my liitokala lii-m4s battery charger and it has a 5% variance. 18350 with high mAh are getting hard to find and I recommend you get these. 1400mAh batteries.
