2 Pcs 18650 Rechargeable 3.7V High Capacity 3500mAh Genuine18650 Flat Top Battery for Headlamp, LED Flashlight

Good quality battery. I haven't performed a capacity test on it yet but it seems to be accurately rated. I needed this to replace a lower-capacity 18650 which was a button top. This one isn't so I had to plop a small magnet on the positive terminal to make it the same size. Works perfectly.

Bought these for extra power for some of my electronic hunting devices. Works good for me.

I bought these to replace a battery pack in a flashlight that takes two of these batteries but it was configured in a way that I couldn’t duplicate. However they did fit another flashlight that I have that only requires one at a time

They work well, hold a charge and recharge quickly. I’m not sure what else you’d want to know.

Would not hold charge straight out of the box.. threw out…

I need these for my cordless drill, exact replacement, and reasonably priced. They do work excellent! 👍

I am sure battery is great… if it fits into battery compartment. The + side has a large metal bowl making it larger size and not able to fit into vape unit, vape door does not close

they are good battery's
