Can my Fenix 18650 lithium-ion batteries be left in a below zero storage area for days at a time and still function when the light is needed?Updated 2 years ago

Fenix 18650 batteries can be both stored and used in a range of -4º F to 140ºF.

It is important to remember that cold temperatures cause lithium-ion batteries to drain at a quicker pace both while in use and not.
