It can get well below freezing here. Does cold even bother these newer lithium batteries?
Not really. See table 2 here (a ways down the page)
Cold generally slows degradation.
But using them at cold temps is bad
Temp has an effect on all batteries. Wouldn’t hurt. And keeping it dry will keep metal parts from rusting as quickly
Storing my batteries indoors was a requirement for having them replaced under my GreenWorks warranty. I recommend checking yours just in case.
IIRC heat is the bigger issue for lithium batteries.
They’re temporarily less effective in cold weather but excessive heat is the battery killer.
Heat is the killer for car batteries too; much to my surprise, I had to buy far more in south Texas than upstate New York. Cold makes batteries less capable, but heat accelerates degradation dramatically.
