2 Pack 14500 Battery 3.7V Rechargeable Batteries, 800mAh 14500 Rechargeable Batteries 3.7V Battery for Flashlight, Toys etc.

Battery casing split open after a few minutes of use in a flashlight...Update: It wasn't the fault of the battery, it was the flashlight I was using that was getting so hot it causing the plastic casing to shrink. The same thing happened to a different brand of battery...

Product arrived on time and with about an 80% charge ready to go. Worked for my 14500 specific battery need inside a toothbrush. Would recommend.

The battery works good but is nowhere near 800mAh. My chargers are getting to 321mAh of charge.

Works great in my torch lights

Oversized just enough not to fit in my wuben X2 pro flashlight. Might fit ok with some modifications to the rubber bumper in the battery compartment but that is a safety feature so the batteries don't damage the circuit board when dropped. Maybe thin the rubber a bit might work then. Batteries seem well made otherwise. Should fit fine in most anything else as the difference in size is very slight. My flashlight is just picky.

From the description, I thought that these were standard AA batteries, but they are noticeably not. These will not fit in the same battery compartment that a normal AA battery would fit in. As such, I'm unable to determine if they actually work. They should not be listed as AA batteries.

Long lasting power to size.

They work well and were easy to install. Good videos on You-Tube. Too new to know how well they will stay charged.
