Hi,
A quick question on charging batteries. I have a 2001 E350 with 2 batteries--1 regular one for the engine, and a deep discharge one for the RV. Is it OK to charge both at once without disconnecting them from the usual wiring? If this is OK, should the charger be set for deep discharge or regular?
In the past, I have always disconnected 1 lead from each battery, so that the charger current only goes to 1 battery at a time, and cannot go across the alternator...
Am I too paranoid?
