Port/House Bank is two brand new Group 31 lead deep cycle batteries. Stbd/EIM Bank is two Group 27 lead dual purpose batteries installed in 2013. They are connected to an Intellipower PD2040 converter/charger.
I have been seeing volts only at 12.4 on the Stbd/EIM bank, while the other bank voltage is 12.6. So Stbd should likely be replaced as well. I know that the chemistry has to match across the banks, but does the Group number need to match for both banks? And does the type (starting vs deep vs dual) have to match for both banks?
I could not easily find how multiple bank chargers work. Is it one output to each bank? Or do the chargers use a different output for each bank?
