Abstract: A battery charger for charging electric motor-powered toy vehicles with self-contained rechargeable batteries, the charger including a self-contained charging battery housed in a simulated vehicle service facility such as, for example, an automotive service station gasoline pump including a normally open electrical push switch connected in series with the charging battery and an electrical charging current delivery cable and connector resembling a fuel dispensing hose and nozzle. The selfcontained charging battery has a greater nominal potential than the vehicle''s rechargeable batteries and the charger electrical circuitry includes a series connected current limiting resistor to protect the rechargeable batteries from excessive sustained charging current flow.
