  • Adapter for a power tool battery
    Patent number: 6525511
    Abstract: An adapter for a power tool battery. The adapter enables a battery having a first configuration, such as a “slide-on” configuration, to be used with a power tool and/or to be charged by a battery charger having a second configuration, such as a “tower” configuration. The adapter may also enable a battery having one general configuration, such as a “slide-on” configuration or a “tower” configuration, and a first connecting structure to be used with a power tool and/or to be charged by a battery charger having the same general configuration, such as the “slide-on” configuration or the “tower” configuration, respectively, and a second connecting structure different than the first connecting structure.

  • Battery charger, method of and software program for operating a battery charger, and method of and combination for charging a battery
    Patent number: 6456035
    Abstract: A battery charger, a method for charging a battery, and a software program for operating the battery charger. The battery charger is capable of charging different types of batteries and capable of operating on alternate sources of AC power or alternate sources of DC power. Also, the battery charging circuit will not operate if one of the power source, the battery, the power switch means and the control means (including the Microcontroller) malfunctions. In addition, in the battery charging circuit, the battery under charge enables the operation of the battery charging circuit.
