How many hours should my Pathfinder Plus battery last?
1. The Pathfinder Plus battery pack should last for 12 hours of normal use.
2. If you are using the Internal Tracker headpointer, battery time could be reduced to 6 or 7 hours.
Note: The Internal Tracker headpointer is an internal camera in the Pathfinder Plus. The user wears a reflective dot which allows him or her to make selections on the overlay. The camera is always running whether the Pathfinder's backlight is on or off.
3. If your Brightness and Contrast settings are set extremely high, this could also cause the overall battery time to be reduced by an additional hour. 
4. If your Backlight Shut Off is turned Off instead of being set to 5 or 10 minutes, the display will always be On and the battery could loose an additional hour or more of battery life.
