Abstract

The battery charging methods used by many prod- ucts employ a temperature sensing circuit to disable the charge current if batteries are extremely hot or cold. The present specifications allow for charging only in the temperature range of +S"C to +45"C. This invention utilizes a circuit internal to the battery which extends the charging temperature range beyond those normally spec- itied, while utilizing existing chargers in the field with- out catastrophic damage to either battery or charger.
