    Default Battery Question

    I have a 3 bank Minn Kota Precision charger hooked up to 3 series 27 Walmart batteries. After staying on charger a week, the Batteries read as follows:
    1. 12.0v. 2. 12.7v. 3. 12.9v.

    Does this look like weak batteries?

    The 12.0 voltage sounds a little low. Possibly that battery has a weak cell.
    Have you noticed if the batteries don't last as long /troll as long as they used too be before being depleted?

    Now would be a good time to check specific gravity in each cell with a tester, and make sure each charger bank is putting out.

    Very good idea. That will let you know the health of the battery pretty quickly

    Yes, that's what got me looking and checking. That and the fact that my charger wouldn't show the 12.0v battery fully charged.

    I am am thinking weak cell. It would be worth swapping the battery to another bank on the charger to verifiy that bank is charging correctly. If you swap it to a different bank and the battery still does not charge fully then it is a battery problem, if the problem moves to the other battery it would be a charger problem

    Thanks for the help. Dead cell in #1. Weak cells in #2. $200 and two new batteries later, Iím back in business.
