I have never done this before but so I wanted to ask the pros for advice. First my boat is bone dry and doesn’t leak anywhere. The bildge pumps are wired directly to a bus bar to the battery power. Should I turn off all breakers for the batteries one at a time or turn the perkos to the off position? Or don’t do either? The batteries all read good in each cell but I’m putting about 1/4 or more in 8 batteries each week. I want to stop the drain. They are not boiling over.
