Lithium Ion batteries prefer a partial rather than a full discharge. Repeated full discharging robs the battery of its capacity (useful life), the Lithium Ion battery prefers shallow over repetitive deep discharge cycles.
Besides cycling, the performance of the Li-ion is also affected by aging. Capacity loss through aging is independent of use however the capacity is affected by both aging and usage.
Battery wear-down on lithium-based batteries is caused by two activities: actual usage or cycling and aging. The wear-down affects by usage and aging apply to all batteries but this is more pronounced on lithium-based systems. The Li-ion batteries prefer a shallow discharge. Partial discharges produce less wear than a full discharge and the capacity loss per cycle is reduced.
Simple Guidelines to extend useful life of the battery
Charge the Li-ion often, except before a long storage. Avoid repeated deep discharges.
Keep the Li-ion battery cool. Prevent storage in a hot car. Never freeze a battery.

You can avoid having to completely re-set your personal settings by using the back-up utility pre-installed on your MobilePro P300. To do so, tap Start --> Programs --> My Settings and tap Backup Utility and follow directions to back-up personal settings onto a SD or CF card. You may also use your desktop Microsoft ActiveSync software to save your MobilePro P300 personal settings onto your PC. To do this you open the ActiveSync window on your desktop and go to Tools --> Backup/Restore and follow instructions.
This problem may occur if the user allows the batteries to discharge to a state where the MobilePro must shut itself down. This state may cause the system storage memory to become unstable requiring a "hard" reset after the system has been fully charged again. Failure to perform the hard reset may result in data loss at a later time. The user manual states that if you receive a message indicating that the batteries are low, immediately connect the AC adapter to the device.
The solution is to perform a "hard" reset after fully charging the internal batteries, and then install the service packs, software updates and user software.

No the coin cell backup battery is not rechargeable.
If the MobilePro 900 back up battery is low it should be replaced. The battery is a CR2032 coin-cell battery, which is very common and can be purchased at most department and drug stores.
Refer to section 1-7 of the “MobilePro 900 Handheld PC’s User’s Guide” for detailed replacement instructions.
On MobilePro systems, which both batteries have fully discharged, the user must perform a hard reset after charging the batteries for approximately 10 hours to ensure proper operation. If the systems fails to power on the user must perform a "hard" reset to initialize the power management circuitry.
