as i acquired more (mostly 18650) cells, the older, or the less capacity, or the less desireable cells? go to less used and lower power lights… my “better” cells end up in newer, more powerful, or more used lights.

anything that charges and holds power and provides safe, useable meaningful runtime in something? still gets used.

theres usually SOMEthing laying around that can use it, even if i have to remember and dig out an older light i normally wouldnt even dream of laying around with a battery in it. If all i DO is keep a battery laying in it, and only use it when i am sitting right there, at least its used a little.

theres the occasional GEM doing this… i “blew” an old light, an 802 style light… then got into aspherics. I never thought i would like the light much anyways… on a WHIM i threw a battery in it, and LOW still worked…

the reflector only getting 120ma of power? still made the light USEFUL around the room and yard enough, i realized i actually LIKED it, and that it deserved a driver upgrade.

if i tossed any batter that wasnt OCD approved? i wouldnt have “too many” laying around… i wouldnt charge up unloved batteries for unloved lights and leave them laying around. SOmetimes? i “rediscover” a light i used to like, and end up liking it again.

There is enough of a difference between dangerous and “like new” that for a lot of us, “OK” is just fine, for lots of jobs. To be clear dangerous cells should be recycled, but cells with less then 2x the new resistance still can do a lot of work. at 3x I find them marginally useful and at 4x they are pretty much dead.
