ABSTRACT:
Apparatus for extending the battery life of a seasonal-use battery. The apparatus is an improvement in a seasonal-use device having a battery charging system, wherein the battery charging system includes a voltage step-down device coupled to the charging system. The improvement includes a mechanism integral the battery charging system for providing a maintenance current to the battery proximate the battery's self-discharge rate. A mechanism is provided for coupling the battery charging system to an external power source. The apparatus for extending the battery life may also be coupled to the seasonal-use device system controller.
