This might be a question for the Green Room battery guys... but it's gear related... but it's not "wood gear"... Each year my mower (Deere 757 ZTrak) sits out the winter in a shed, which is dry but cold. I have never done anything with the battery other than just leave it in the mower. Every year, someone tells me that battery will be dead by spring, but every spring I go out and fire up the mower, and it just starts with no trouble. Now, maybe I shouldn't mess with what's been working, but my FIL gave me a battery maintainer last week. I'm thinking of hooking it to the ZTrak for the winter, but have this feeling in the pit of my stomach that this will be the thing that finally kills my battery. What do the experts say?
