    Batteries showing fully charged after using them all day.

    Hey everyone, I have a 2008 Skeeter 20I with a 36 volts Minnkota Ultrex trolling motor. About a month ago I took it out and when I come in I put the batteries on charge. I have a 4 bank Minnkota battery charger on board. And I have 4 Optima batteries on board. But when I plugged in charger all light should show yellow. But 2 of them show fully charged (green)and 2 of them show yellow. Not sure what is happening it feels like I'm running a 24volt. Has anyone had this issue? Please help,thanks.

    Test the batteries individually with a voltage meter.

    Bilge,
    Change the leads and see if the problem follows the switch.
    How old are the batteries, and are they AGM or wet cell?
    Dependent on your charger model, does it allow you to choose which type
    of battery you are charging?
