1. An indicator device for a tool comprising:
- a power source adapted to supply power to the tool and having a voltage level;
a control circuit electrically coupled to the power source and adapted to monitor the power level of the power source; and
an indicator electrically coupled to the control circuit and adapted to be activated when the control circuit determines the voltage level is at or below a predetermined amount corresponding to a predetermined amount of time in which the power source can supply power to the tool.

Abstract
An electronic device or tool including an indicator adapted to provide an indication when a predetermined amount of time of operation of the electronic device, for example about 10 minutes, remains in the power source. The indicator device indicates to a user that the user has a certain amount of time of operation of the electronic device before the electronic device will shut down and become inoperable.
