A combustion tool (100) having a circuit for conserving battery power includes a battery assembly (114) to power at least a portion of the combustion tool, a control circuit (512) to place the combustion tool in an active mode or a low power consumption mode, and a motion sensing circuit (502) to indicate a movement of the combustion tool and to indicate a non -movement of the combustion tool. A timer (506) is set when a movement is detected and resets each time a new movement is sensed. If a new movement is not sensed when a predetermined amount of time has elapsed, the combustion tool enters into a low power consumption mode. The movement may be a vibration or a tilt movement. The motion sensing circuit (502) enables the tool to be actuated without any unnecessary priming when motion is sensed and only minimal current is consumed when motion is not sensed, conserving battery power. |
