If one batt is lower or weaker than the other, the better batt could
get overcharged and weaker overheat. This is using a commercial
charger. Having said that, semi trucks typically use 4 batt at a time
and almost never get disconnected and are charged as a batt "pack".
Touch the sides of the batteries after a charge to see if one is
hotter that the other. If so, stop charging those 2 batt together.
