ABSTRACT OF THE DISCLOSURE A multistation charging system is provided for charging batteries within a plurality of cordless tools, appliances or the like, each of which has at least one rechargeable battery therein. A plurality of modules, which act as charging stations, are arranged substantially adjacent to one another. Normally closed pairs of conductive contacts are provided in each of the modules. The electrical pairs of contacts in the modules are connected in a series circuit arrangement with each other. On or in one of the modules, electrical connection is provided to a single current regulated solid-state charging device which produces charging current pulses. The device may at least in part be in one of the modules, or a line cord or in a plug attached to the line cord. Each of the modules removably supports a respective tool or appliance and each tool or appliance has means for electrically connecting the respective battery therein within the series circuit arrangement and in series therewith only one wall outlet or a.c. power connection is required. Any combination of batteries per tool or appliance and any number of tools or appliances may be provided. Any number of the modules may be unoccupied, yet the series circuit is complete. The modules are of standard construction, allowing charging of batteries or cells within many different tools and appliances provided with standardized connections.
