Abstract: A battery mechanism is disclosed. The battery mechanism in one embodiment includes battery assemblies, a switching mechanism, and an actuating mechanism. The battery assemblies are removably mounted to the switching mechanism. The switching mechanism has a non-energized position in which the battery assemblies are electrically disconnected from the switching mechanism. The switching mechanism also has an energized position in which the battery assemblies are electrically connected to the switching mechanism. The actuating mechanism is connected to the switching mechanism, and switches the switching mechanism between the non-energized and the energized positions. The actuating mechanism preferably is activated remotely, improving personnel safety. The number and make-up of the battery assemblies may be varied to provide for different voltages.
