Abstract
A dual chemistry battery system is disclosed that preserves the voltage of the primary battery in a vehicle while connected in parallel to a secondary battery. The system utilizes batteries with different chemistry and voltage output characteristics to maintain at least the necessary charge in the primary battery for starting the vehicle. Preferred embodiments utilize a lithium-ion Auxiliary Power Unit (APU) to preserve the charge of the vehicle's primary lead acid battery.
