Abstract: An automatic battery charging circuit for use with battery powered vehicles such as golf carts includes an automatically timed charging switch which is connected in parallel with the conventional manually timed charging switch of the battery charger. The automatically timed charging switch includes an electrical clock connected across the power line of the charger. When the charger is plugged into the power line, the clock closes the terminals of the automatically timed charging switch for a brief period of time on a periodic basis. This prevents the batteries of the vehicle from becoming substantially discharged during extended periods of non-use, thereby increasing the life of the batteries.

Abstract: A battery assembly apparatus comprises a device for delivering depolarization mix into a dry cell can. Another device inserts a carbon rod into the depolarizing mix in the dry cell can. A mix washer insertion device consolidates the depolarizing mix by pushing a mix washer against the depolarizing mix.
