ABSTRACT:
A wireless microphone is provided with a recharging circuit which determines if a battery in the microphone is a rechargeable type and can be safely recharged. The recharging circuitry in the microphone, which could also be included in other handheld wireless devices, determines if a battery is in a charged state where it is difficult to distinguish rechargeable and non-rechargeable batteries. If so the battery is discharged until the battery reaches a charged state where non-rechargeable batteries can be readily distinguished from rechargeable batteries.
