12 or 24 volt charger??
If 12, Do NOT connect to batt. A pos. and Batt. B neg with jumper in place!!
I prefer to charge each battery independent of each other with positives disconnected so I can be sure of the condition of each battery. When charging 2 batteries together, one could be going bad and not be detected until it leaves you in a mess.
I just had one of my trolling batteries go bad, and was less than 6 months old, warranty replaced.
I was told to not undo the jumper, and can use 2 different chargers, hook one to each battery. I did it, and no problem, both batteries 100%.
