The invention provides an electrical combination including a power tool having a housing supporting a motor, which is operable to drive a tool element. The electrical combination also includes a battery and an adapter supportable on the housing of the power tool and electrically connectable to the power tool and the battery such that the adapter transfers electrical power between the battery and the motor. The adapter has a locking arrangement engageable with the battery for preventing the adapter from being removed from the power tool housing while the battery is connected to the adapter.

Adapter for a power tool battery

A method and apparatus to automatically reverse the motor of a power tool, such as a dispensing gun or similar tool. In some constructions, a controller automatically reverses the direction of plunger movement and removes the plunger from contact with the back wall of a cartridge. The controller has a trigger switch that is coupled to a power source, such as a battery, and includes a main power on/off switch and a potentiometer. A protection or secondary switch is coupled in parallel to the main power on/off switch. A power supply circuit and a commutator are each coupled to the main and secondary switches. An overload sensor is coupled to the commutator. The controller includes a programmable device that is coupled to the power supply circuit, the potentiometer, the commutator, and the overload sensor. The programmable device is operable to sense actuation and deactuation of the main power on/off switch, read an electromotive force from the potentiometer, and, upon sensing deactuation of the main switch, send a control signal to the commutator to reverse current flow therethrough for a predetermined amount of time, and deactuate the secondary switch when the predetermined time has lapsed.

Power tool and motor controller

An electrical combination, a method and a power tool. An electrical combination may includes an electrical component including a component housing, and an electrical circuit supported by the component housing, a first terminal assembly at least electrically connectable to the electrical circuit, a second terminal assembly at least electrically connectable to the electrical circuit, a first battery including a first battery terminal assembly electrically connectable to the first terminal assembly to electrically connect the first battery to the electrical circuit such that power is transferable between the first battery and the electrical circuit, and a second battery including a second battery terminal assembly electrically connectable to the second terminal assembly to electrically connect the second battery to the electrical circuit such that power is transferable between the second battery and the electrical circuit. The second battery may be different than the first battery. At least one of the first battery terminal assembly is not electrically connectable to the second terminal assembly and the second battery terminal assembly is not electrically connectable to the first terminal assembly.

Electrical combination including a battery pack

An electrical device, such as a battery charger, a method for operating an electrical device, a method for charging a battery, and a software program for operating the electrical device and/or the battery charger. In some aspects, 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.

Apparatus and method of activating a microcontroller

An electrical combination including a power tool manufactured by a first power tool company, the power tool including a tool housing and an electric motor supported by the tool housing and operable to drive a tool element, a battery manufactured by a second power tool company, and an adapter separate from and connectable between the battery and the tool housing to support the battery on the tool housing.

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 &#x201c;slide-on&#x201d; configuration or a &#x201c;tower&#x201d; 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 &#x201c;slide-on&#x201d; configuration or the &#x201c;tower&#x201d; configuration, respectively, and a second connecting structure different than the first connecting structure.
