A tool with a battery, an electrical motor, and a control system. The control system has a trigger control that connects the battery to a timer and a voltage monitor. The trigger control has a user actuated switch and a timer actuated switch. At the end of a tool operational cycle, when the user is not actuating the user actuated switch, the timer actuated switch can supply electricity to the control system. After a predetermined period of time, the timer actuated switch can then automatically electrically disconnect the control system from the battery to conserve battery power.
