3.8  Monitoring The Battery And Maximizing Run Time
Note: When the main battery is at 50% capacity, a ‘low battery’ warning is dis-
played. When the battery is at approximately 10% capacity, a ‘very low 
main battery’ notification bubble appears.
Under normal operating conditions, fully charged Standard Batteries hold a charge 
for up to 8 hours. High-Capacity batteries can hold a charge for up to 12 hours. 
As Lithium Ion batteries age, their capacity decreases gradually, and they are 
generally considered depleted after approximately 2 years of use (less than 60% of 
original capacity remaining). Keep in mind however that heavy usage or operating 
the unit at temperature extremes will shorten the battery life.
Lithium Ion batteries do not require conditioning cycles and the WORKABOUT 
PRO 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 the largest drain on the battery. Try to keep its 
brightness as low as possible.
