Seems like there lots of opinions on temperature storage on these batteries ranging from 77F degrees to 105 or 149F. My ego 56v batteries (5 and 9 AHs ) are 400 plus to replace so want them last as long as possible. I also brought in my 12V and 21v also.
Even with garage well ventilated the temperature builds about same in late afternoons to early evening. I figure I got over 600 Bucks in these batteries and want them to last long as possible. I also let them cool before recharging.
I checked my car battery temps after trip it’s temps are 110 to 115F nothing I can do about that except raise car hood to let heat out so it don’t set there and cook. I guess that’s why car batteries don’t last very long here in Florida?

I leave my lithium battery power drills in the garage when I leave to go up north. I've also left my lithium battery powered golf cart in the garage. I've been doing this for three years without any issues. I do not leave any of them on the charger when I'm gone.
