Hard to know what the best thing to do is, I guess just keep using your stuff.
Back when I had the time I would always just pull all the batteries in the unused equipment and store them in the warm boiler room on a pine board on the floor. Charge them in the spring when it was time to get going.
When I was a kid and bought my first motorcycle, the guys said, “ come winter, put the battery in the cellar with a trickle charger hooked up to the cellar light. That way, every time your mom sends you down to get a can of beans out of the root cellar, the battery will get some charge”.
I got a friend that made up a pulse charger recently. Swears he’s gonna rejuvenate all his 15 year old batteries.
Lately I been using Battery Tender Jr’s.
Sorry, just some random thoughts..
