18650 Batteries

What do you lot use these for? I
bought some expecting them to fit into my cree hand torches but they don't. Bought 4 of them and a charger from China so not much chance of them being returned.

18650 batteries

Use my 18650 4000m AH in my CREE 3000 lumen headlight.

I use them in my Fenix headtorch and my Lezyne mountain bike lights.

most of the cree headlamps use them but some of them are poor and others are quite good

Only 18650 battery I use is an Eagletac 3.7 Volt Li-ion 3400 mAH. I use it in my Fenix flashlight which I fix facing upwards onto my rod rest with a quick release bike mount and it illuminates all my rod rings so I can see bites, changed over to this as I hate using tip lights, nearly snapped the tip off my rod more than once when the line getting caught over the tip light while casting.
