Battery capacity recovery apparatus and method

A telecommunication device for at least one of a landline network and a wireless network, wherein the improvement comprises:

• a battery;
• a recharge detector that detects a recharge status of the telecommunication device and that generates a status mode of the battery;
• a voltage detector that detects a voltage level of the battery and generates a voltage status of the battery;
• a controller that receives the status mode and the voltage status from the recharge detector and the voltage detector, respectively, to generate a first control signal;
• a first switch responsive to at least one control signal and coupled to a recharge terminal for receiving a charging battery;
• a resistor coupled to the first switch and the battery;
• and
• a second switch coupled in parallel with the battery and a ground voltage, the second switch being responsive to an inverted first control signal, wherein
• the first switch is turned on and the second switch is turned off when the voltage level of the battery is below a prescribed voltage level for charging the battery, and the first switch is turned off and the second switch is turn on when the voltage level of the battery is above a prescribed voltage level to discharge the battery.
