Introduction
The mobile computer uses a Nickel Metal Hydride (NiMH) battery. This
section provides some important information about these types of
batteries and ways to extend their life.
Practical Battery Tips
Tip 1. Getting the most from your battery
• Your battery will last longer during the day if it is used and charged
between 10°C and 30°C (50°F and 86°F).
• Charge the battery nightly where the temperature will remain around
20°C (68°F).
• Set up your system to automatically suspend (turn off) while the
battery is charging.
This can be done by enabling the Suspend on AC Power option
under the Power, Suspend/Resume Control menu in the System
Configuration Utility (SCU). This allows the system to automatically
suspend while it is connected to external power.
• Use the Battery Maintenance application (located in the computer
tools folder) to deep cycle discharge your battery. Deep cycling your
battery reconditions it and eliminates memory effect. Follow these
guidelines when deep cycling:
- Deep cycle your battery when requested, which may be as often
as 3 months, depending on usage.
- For the best conditioning, deep cycle the battery where the
temperature will remain around 20°C (68°F).
- Leave the display tilted open and allow unrestricted airflow so
excess heat can escape from the battery compartment and
prevent the battery from overheating.
- Consider running the deep cycle process over a weekend because
it can take up to 40 hours to complete.
