Battery life extender apparatus
First Claim
1. Apparatus for precluding discharge of a rechargeable battery used in an intermittent-use device, the apparatus comprising:
- means for providing to the battery a maintenance direct current proximate the specific battery'"'"'s discharge rate while the device is not in use, including a non-voltage regulated power supply having a direct current output, and means for transmitting the direct current to the battery as said maintenance direct current; and
means for coupling the means for providing a maintenance direct current to an external power source.

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.
