I’m using AA rechargeables for my toy train remote control system. I likely won’t be running the R/C unit for some time until I can get my track finished.
Can rechargeables be left inside or should they be removed when not in usage?
Since it will take less than 10 seconds to remove them from your transmitter, I’d remove them for the long haul. Leave ém in if just for a month or two…in your house, of course.
