Well I hate to use anything other than rechargeables even if they don’t work as well.
I suppose I should up my battery game though - problem is that I have a drawer full of eneloops that still have a ton of life in them. But maybe just for the door lock I should get some lithium rechargeables, which at least should hold their voltage until they’re dead, unlike the eneloops that drop down below 1.3v in no time.
