So I disconnected the shore power and turned off the house battery switch, I waited an hour then tested the batteries, and the measurements were as follows: the voltage ( using a millimeter was 12.83 , and when I used the hydrometer, every cell in the first battery tested 1.3 and every cell in the second parallel battery was 12.65 , are these too high? Is it possible to be because of overcharging?
