I would like to start off by saying there is a lot of info about cordless batteries. Which is the best battery, type of charger, which have memories, which don't, self discharge rates, effects of temperature. Look long enough and you will find a ton of info and you won't know what to believe anymore.
I can say first hand cold temps play havoc with both my Li-ion and Ni-MH batteries. Try to use one when it's been left in truck at 0 degrees and like other batteries they don't work well. So I've been warming them up in the house before charging.
Then I decided to do a little experiment this morning. Make a trickle charger that charges battery at 0.1% of C. Connected trickle charger to a fully charged battery on workbench in unheated barn. I'll post back in a few days with my findings. Has anyone used a trickle charger on their cordless batteries 24/7 to keep batteries up to speed in a cold environment?
