Over the years I have taken out my TT batteries and hooked them to a trickle charger in my garage during each winter. I now have the TT under covered storage at a local storage yard which has electric...
So I am going to display my ignorance, once again -- I had thought that if a battery is left disconnected, it will discharge about one percent per day. And after a couple of months, that discharge could shorten the battery's useful life.
Is that not true? Because if a battery can be charged, disconnected, and left alone for a long time with no damage, I am wasting electricity. I store mine in my garage (which never freezes) and keep it on one of those Battery Minder Plus gizmos.
