A battery tester determines a remaining level of charge of a battery mounted within a separate electronic device having an audio jack. The battery tester includes a plug and a circuit having a high impedance input amplifier. At least one electrical contact of the plug is electrically coupled to an input of the high impedance input amplifier. The plug is removably insertable within the audio jack such that the battery of the separate electronic device is electrically connected to the input of the high impedance input amplifier. When electrically coupled to the battery, an output of the high impedance input amplifier provides a signal proportional to the remaining level of charge of the battery, whereby the remaining level of charge of the battery is obtainable by the battery tester without having to remove the battery from the electronic device.
A battery tester for determining a remaining level of charge of a battery mounted within a separate electronic device having an audio jack, comprising a circuit including a high impedance input amplifier and a plug having a contact that is electrically coupled to an input of said high impedance input amplifier, said plug being removably insertable within the audio jack such that said contact of said plug electrically connects the battery to said input of said high impedance input amplifier, said high impedance input amplifier having an output that produces a signal proportional to the remaining level of charge of the battery, whereby the remaining level of charge of the battery is obtainable by said battery tester without having to remove the battery from the electronic device.
A combination electronic device having an audio output jack, and a battery tester for use in testing the charge level of an internal battery mounted within said electronic device;
