Abstract
An electrical system of a vehicle has a starting battery and a reserve battery. The charge of the starting battery is maintained by a charge maintenance device under control of a controller which couples energy from the reserve battery to the starting battery during periods when the vehicle is not being used or during periods of operation where the starting battery voltage requires additional charge.
