Battery Information
The computer's primary battery is a rechargeable Lithium-Ion (Li-Ion) pack. DO NOT use other
batteries. They may damage your handheld computer.
After inserting a new Li-Ion battery pack, charge it to 100% before use. This ensures that the battery
p
ack's power gauge calculations will be correct. Frequent incomplete charges lead to progressively
larger errors that only a full charge can fix. Charge on AC power at least 7 hours to ensure the internal
backup battery is also fully charged; however it may take longer if the ambient temperature is extremely
hot or cold.
The internal backup battery retains data up to 48 hours if the main battery pack is fully discharged or
removed. Its charge is automatically topped-off whenever the handheld computer is awake and on
external or main battery power. To ensure data integrity, the main battery should always be kept charged
and important data should be saved in non-volatile memory, such as on the System
CompactFlash card.
Whenever possible, use the AC power adapter with the handheld computer to conserve the battery pack.
The AC Adapter charges the battery pack and supplies a maintenance charge to the backup battery.
Ideally, you should charge your battery pack at the end of every day. Proper charging practice keeps
both batteries in good condition.
If you do not intend to use your handheld computer for an extended period of time, back-up all
important data in non-volatile memory, such as on the System
CompactFlash card.
