Monitoring the Battery and Maximizing Run Time

Note: When the battery is at 50% capacity, a 'low battery' warning is displayed. When the battery is
at about 10% capacity, a 'very low battery' notification bubble appears.
As Lithium-Ion batteries age, their capacity decreases gradually, and they are generally considered de-
pleted after approximately 2 years of use (less than 60% of original capacity remaining). Keep in mind
however that heavy usage or operating the EP10 at temperature extremes will shorten the battery life.
Lithium-Ion batteries do not require conditioning cycles and the EP10 battery system (including chargers)
requires no user interaction to maintain peak performance.
To maximize the run time of your batteries, consider the following:
• The display backlight is a large drain on the battery. Try to keep its brightness as low as possible.
• The EP10 is 'event' driven – that is, when it is not in use, the EP10 reverts to sleep mode (even when it
appears to be running), saving battery power. Events include a key press, touchscreen taps and scan
triggers. Power consumption is reduced if you avoid unnecessary events, and allow the EP10 to sleep
as much as possible.
• The battery is a 'smart battery' with built-in intelligence.
Tapping on the Start>Settings>Power icon displays a dialog box that provides detailed information about
the battery status of the battery installed in your EP10.
