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?

All of my lawn equipment is lithium ion now. To help address the hot garage issue I ran a power strip into my garage air handling closet where all of the charging takes place. With the AC leakage that takes place as it moves up and out into my house, the closet stays around 80. Cooler would be better, but I don't want a bunch of batteries taking up space in my house. Going on three years, all the batteries are fine.
I also have a lithium ion golf cart. Not much I can do about a hot garage there. However, I don't leave it on the charger once it is fully charged. Unplug it, and don't recharge until I've run it down to at least 85%. Figure that would also protect me from a power surge that could cause problems if connected.
