ABSTRACT:
In one embodiment, a consumer electronic device has a rechargeable battery, battery safety circuitry, and consumer electronic device circuitry with a controller. The rechargeable battery has a present temperature and a presently available effective capacity, and provides power to the electronic device via the battery safety circuitry. The controller determines whether the rechargeable battery might have, at a battery temperature greater than the present battery temperature, a potential effective capacity greater than the presently available effective capacity and, upon such determination, provides an indication to the user that additional effective capacity might become available if the battery temperature were raised.
