Hi, Sailmc.

I wasn''t trying to dispute anything you said. I was just regurgitating (in summary form) what the marine industry battery experts seem to be saying. I don''t have any of my references in front of me, but it may be that cold temps actually slow the rate of self-discharge (because it is a chemical reaction after all).

In my winter storage of batteries (tractor, motorcycles, etc.) in my basement at 50F, I have absolutely noticed a marked discharge over time, although now I don''t let it get down very far before I bring them back to full charge.

I''m glad to hear you have been having success in your situation. If it''s working, don''t change it.

Fair winds,
Duane
