Abstract

A portable radio (306) provides a selectable and/or automatic battery conditioning mode of operation (400). Battery conditioning is achieved by discharge state (410) that discharges the battery down to a predetermined threshold using existing radio circuitry (308).

Claims

1. A method of discharging a battery, comprising the step of applying a predetermined radio load to the battery until the battery voltage reaches or falls below a predetermined conditioned threshold.

2. The method of claim 1, wherein the step of applying a predetermined radio load includes the step of activating power amplifier circuitry.

3. The method of claim 2, wherein the step of applying a predetermined radio load further includes the step of activating light emitting diodes (LEDs).

4. A battery powered portable radio, comprising:

a battery; and

a radio coupled to the battery, wherein the radio includes circuitry operating both as radio circuitry and as selectable conditioning circuitry for the battery.

5. The battery powered portable radio of claim 4, wherein the circuitry includes a power amplifier.

6. The battery powered portable radio of claim 4, wherein the circuitry includes light emitting diodes.
