Maintenance Free Group 31 Batteries

[Gregory OConnor]

Rob, I think they become maintenance free when The seal and lid trap
in the moist air that later condenses on the sealed lid then refills
the cell. I think the maintenance free fluids produce less pressure
when heated or the container and caps are designed to handel the heat
expansion while charging and using. Maintenance free is an
advertising term that means " Designed to be replaced at end of
warranty period"
