How to charge a bank of Batteries connected in Parallel



When you have more than one battery in a bank of batteries connected in parallel and the bank has been discharged below 10.5 Volts or 100% depth of discharge, it is advisable to recharge each battery separately with an automatic charger.  Failure to do this can lead to batteries accepting a higher than required charge rate due to the charger not being able to determine the individual internal resistance of the batteries. While this procedure may take extra time to fully charge your parallel bank, it will take less time in the end than having to replace them or claim a warranty which may not be accepted due to incorrect charging of the batteries.

Don’t let this happen to your battery due to incorrect charging
