Abstract
The battery apparatus has a circuit to turn off a switching device and suspend charging when rechargeable battery voltage exceeds a specified voltage, and to turn on the switching device and resume charging when rechargeable battery voltage drops below the specified voltage. The switching device is switched on and off to pulse charge the rechargeable battery. When cut-off of charging voltage to the rechargeable battery is detected, an over-ride circuit forces the switching device on, or a forced discharge circuit discharges the rechargeable battery until battery voltage drops below the specified voltage.
