Secondary battery discharge adaptor
First Claim
1. A battery discharge adaptor for discharging at least one battery, the adaptor removably connectable between a preexisting recharging unit and the at least one battery, comprising:
- a load discharge circuit for discharging the at least one battery;
a discharge detector connected to the load discharge circuit that detects when the at least one battery is discharged; and
a switch connected to the discharge detector having first positions connecting the at least one battery to the load discharge circuit and second positions connecting the at least one battery to the recharging unit.

Abstract
A discharging adaptor connects between an existing recharging unit and a battery, discharges the battery and, automatically recharges the battery after discharging is complete. The adaptor also indicates the battery'"'"'s remaining capacity. The battery discharging adaptor connects between a battery and its recharging unit and is equipped with a load-discharging circuit for discharging the battery, a mechanism for connecting the battery to the load-discharging circuit when power is added, a mechanism for detecting when the battery is almost completely discharged, and a regulator for connecting the battery to the recharging unit, based on the output of the discharge detecting system.
