A rechargeable battery pack that includes a temperature monitoring circuit a rechargeable battery, and a discharge circuit, advantageously provides a battery pack which senses when the battery pack is exposed to a harmful temperature and cause the discharge circuit to discharge electricity stored in the battery until the battery's charge level is reduced to a safe level for the particular temperature. The rechargeable battery has a positive terminal and a negative terminal. The discharge circuit is coupled to the rechargeable battery. A controller is coupled to the discharge circuit. The temperature monitoring circuit is coupled to the controller and measures a temperature of the battery, providing a temperature indication to the controller. The controller causes the discharge circuit to discharge electricity from the battery based upon the temperature indication.
