I have a Fury, X300, tlr1, and some scout lights that aren't used but sit with batteries in them. How often should I change them?
Only if there's parasitic discharge caused by the light. I'd be wary of e-switches for this reason.Does storing them in the light cause them to last less years?
Yeah this is a good point, I've mostly stayed away from 2xCR123 lights for this reason. Too many reports of unbalanced voltage causing voltage inversion and blowing up.The only issue I think about when storing CR123's in a light for years is a gradual self discharge that may vary battery to battery. Especially non US made batteries that may not have been built with a thermal runaway protections. When in a series of say two or three, if one has a much lower remaining voltage than another, the cells try to balance each other out, the higher voltage one(s) trying to charge the other one(s).
Ordinarily this is not an issue, but it is a distinct possibility. If you feel the light getting unordinarily warm shut it off and remove the batteries, prefrably outdoors or in a well ventalated environment.
