How long will the batteries last in the Mimio Xi bar?

Four new AA batteries will provide approximately 40 hours of usage. The power button/LED on the bar will change colors indicating remaining battery life.

The power LED indicators are:

1. Green indicates over 5 hours of battery life remaining.
2. Yellow indicates 1–5 hours of battery life remaining.
3. Yellow flashing indicates less than one hour of battery life remaining.

NOTE: An audio tone from the Mimio Xi bar will indicate when the battery moves from one of these stages to the next.
