Abstract: This is a battery charger for rapidly recharging relatively small-capacity rechargeable batteries. The batteries are recharged by being placed in electrical contact with terminals that are electrically coupled to a source of DC current, a current path being completed through the battery or batteries to be recharged. The charger includes a spring-driven rotary switch that sequentially contacts a discharge terminal and then a charge terminal, the battery being thereby first discharged for a predetermined period of time and then charged for a predetermined period of time.
