A system for controlling battery charging. The system comprises a battery charging device, a temperature sensor, and a controller. The battery may be a Lithium polymer battery, or the like. The temperature sensor senses the battery temperature and outputs a temperature data signal. The controller inputs the temperature data signal and determines if the temperature data is outside of a range with an upper limit and lower limit. If so, the controller disables the battery charging circuit, wherein the battery is prevented from being charged. In this fashion, the battery's lifetime (e.g., number of charge/discharge cycles) is extended. In another embodiment, the system further comprises a display. The controller outputs a signal to the display, directing it to display a message indicating that the battery is not being charged because the temperature is out of the pre-determined range.
