When the vehicle is off the batteries are in parallel and can be charged with a charger or with another car running and jumper cables connected. I did not need to disconnect the two batteries to jump or charge with my maintainer, after the volts were high enough. If the voltage is too low on the battery, depending on your charger, you can have it connected all night and it wont charge the battery. The battery may need to be above a certain voltage before your charger does any charging, mine gave an error saying the battery wouldn't hold a charge, thus the need for another vehicle and jumper cables to get the batteries above the threshold.
I believe others here have had their batteries changed under warranty but I do not remember the thread offhand.
