A rechargeable battery system utilizes intelligent temperature control to enhance and optimize battery cell capacity and performance in low and high temperature environments. A temperature varying element (heating and/or cooling) modifies the temperature of battery cells utilizing an amount of energy that is less than that gained by making such temperature modification. A control circuit optimally control the temperature varying element to maximize battery operation. The control circuit also utilizes the temperature varying element to prevent cell damage in extreme conditions. A battery pack contains a plurality of cells also houses the control circuit, the temperature varying element and a temperature sensor. At least a portion of the control circuit and temperature varying element may alternately be located within a portable electronic device. A second temperature sensor may be added to monitor ambient temperature, and Insulating material may be used in the construction of the battery pack housing.
