Abstract: A compound battery device having a lithium battery and a lead-acid battery includes at least one lithium battery unit, at least one lead-acid battery unit and a control circuit. The lithium and lead-acid battery units are electrically connected in parallel and can have various combinations to meet actual demands of an output voltage. The control circuit is electrically connected to the lithium and lead-acid battery units separately and further comprises a voltage-boosting unit, a voltage-detecting unit, a lithium battery unit management unit and a logic control unit. Thereby, two complementary battery units are connected in parallel, with a control circuit to adjust a voltage thereof, allowing the two battery units to work together to make use of their respective advantages while providing mutual power support. Thus, the compound battery device is capable of more efficient power supply and higher loading, and effectively prevents over-discharge that shortens the battery service life.
