I'm just wondering what the right way to store your batteries for the winter, Do you just remove it and store it in the basement, or keep a trickle charger on it for the winter?
A $30 trickle charger from WalMart will maintain your batteries as well as a $300 everything-but-makes-coffee charger. A stored battery is slowly eating itself alive, that's just how batteries work if not kept charged. An AGM battery doesn't even need water to be added and can be installed inside, unvented, upside down, in an airplane, and under your dinette...But I digress.
