Abstract
A battery pack for providing electrical power to a commercial tractor/trailer vehicle has two 12-volt high-CCA batteries connected in parallel and two 6-volt deep-cycle batteries connected in series to power 12-volt electrical accessories such as devices for creature comforts. The two 12-volt high-CCA batteries provide sufficient cold cranking current for starting the engine of the vehicle. The two 6-volt deep-cycle batteries connected in series are used to power electrical accessories such as devices for creature comforts when the engine is not operating. A switch connects the serially connected 6-volt deep-cycle batteries in parallel with the 12-volt batteries for charging when the engine is running and isolates the 6-volt deep-cycle batteries from the 12-volt high-CCA batteries when the engine is off. The two 12-volt high-CCA batteries may alternatively be replaced with one large 12-volt high-CCA battery.
