I recently wrote on our blog, www.neverwonder3.com, about storing our boats batteries in the basement on the cold dark concrete floor, is this good or bad? Some boaters advised us that we should have kept them off the floor, some say it "really doesn't matter" - what are your thoughts?
We checked with one of our featured bloggers and frequent contributors, Ed Sherman of Ed's Boat Tips. He replies with the following:
No. Concrete at any temperature will not suck the life out of a battery. Urban myth with modern batteries. In ancient times, when battery cases were made of Bakelite and had gooey poured tops moisture accumulation on the outer case would create a conductive pathway for low level ground fault and accelerated self- discharge. Modern plastic cases, as long as they're kept clean and dry will not self-discharge through or via the case.
