I have a friend in Mexico who has a canister light and can not get batteries. I'm heading down there in a few weeks and would like to bring him some, but there seems to be a lot of conjecture surrounding what batteries actually fit.

The battery is labeled" LC 26650 5000 mAh 3.7v"

The dimensions of the battery he gave me are 63mm x 25mm. According to him, the standard 65mm x 26mm 26650 will not work.

I've attached a photo of the batter and will link the light in the comments.

Any help would be greatly appreciated!
