Abstract
A rechargable battery with an internal microcontroller. The microcontroller contains a memory in which data regarding the environment to which the battery is exposed are stored. These data are read by a processor integral with the charger used to charge the battery. If these data indicates the battery may have been subjected to a harsh environment, such as being exposed to an excessive temperature, the charger performs a fulle state of health evaluation of the battery.
