Abstract:
1. An apparatus for disabling charging counter circuitry measuring a total charging time of a battery within a battery charger, comprising: circuitry connected to a pin associated with the charging counter circuitry measuring a total charging time of a battery within the battery charger, said circuitry and receiving a signal from a device connected to and being charged by the battery charger, said circuitry stopping generation of a clock signal by the charging counter circuitry responsive to the signal at a first level wherein the signal at the first level indicates the device being charged by the battery charger is being used while the device remains connected to the batter charger and continuing generation of the clock signal by the charging counter circuitry responsive to the signal at a second level wherein the signal at the second level indicates the device being charged by the battery charger is not being used while the device remains connected to the battery charger.
