18650 Rechargeable Battery 3600mAh Button Top 2 Pack 3.7V Li-ion Batteries for Flashlights Headlamps

Perfect fit. Fast delivery

Correct product. Prompt delivery. No problems.

This is at best an 800 mAh battery. I have a charge that measures that. I get tired of trying batteries, and they aren't close to what's stated on the box. Likewise, I just keep returning them. Maybe they'll get the message.

I got these batteries to power a flashlight I take on walks. Each walk takes about an hour. The brightness of my flashlight is great the first day. About halfway thru day two's walk, the light fades quickly and the battery needs recharged by the time I am done. I would expect the battery to last more than two hours on one charge.

I gave this item 5 stars only because it looked good quality. But I returned it because it does not work in my Fenix headlamp. I think it's because of the length dimension. It's just a few millimeters too short. I discovered after receiving it that 18650 battery dimensions are not standardized.

These are rechargeable flashlight batteries that fit some of the newer LED high lumen flashlights. These batteries charge well and hold their charge as expected. Not much else to say about them other than the work as expected.

These last much longer than the battery that came with our flashlight. Lasts forever and would highly recommend these at replacement batteries.

He's a good rechargeable battery. They seem to hold their charge in power over time. They hold their own against the higher named brands.
