Abstract: A turntable is provided for use in recharging batteries of the type used in battery powered forklift trucks and the like. The turntable includes a peripheral array of charging stations each including a support platform and a battery charger for connection to and recharging of a battery on the platform. The turntable is rotatably driven in a stepwise manner to index the charging stations in succession to a transfer position. A push-pull ram at the transfer position draws a depleted battery from a forklift truck onto the platform of an empty charging station. The turntable is then indexed to move a recharged battery to the transfer position, and the push-pull ram installs the recharged battery on the forklift truck.
