Abstract
An improved battery handle system which provides for safe use of either a rechargeable storage cell or non-rechargeable batteries. This system comprises a battery handle adapted to hold the storage cell, having a positive pole adapted to interact with the charger to provide recharging of the storage cell as desired. The charger has a biased contact pin which makes electrical contact with the positive pole of a storage cell. However, if a battery handle with non-rechargeable batteries is inadvertently connected to the charger, the pin cannot extend sufficiently into the battery handle so as to contact the non-rechargeable batteries.
