For the first time this winter I have stored my batteries on board at 44*N latitude, about forty miles south of the Canadian border. Today I drove up to take a look at the boat, check the stands, and charge the batteries.
I had switched off both banks and separated the paralleled house bank on October 21st. The good news is that when I connected them up again prior to charging the house bank read 12.8 volts on the digital voltmeter on the monitor. That's damn close to the fully charged voltage. The starting battery read slightly lower, but that was on the panel meter which is not too precise.
Cold is good!
I now have no concerns about leaving them through the entire winter without charging.
