I have 3 bank NOCO Genius Charger in my 2011 PII. After fishing Saturday, plugged it in, and everything went to green aside from the 2nd bank after about 6 hrs. Left it on for an additional 6 hrs, but the bank never showed to be green. Finally turned it off. This is only the 3rd time it has been used, but I am unsure of what to check. All connections are good, batteries are brand new (just got the boat on 3-2), and none of the lights are flashing, showing blank etc.. Is there anything else I should check, or will one bank generally take much longer than another to charge with these chargers after use?
