Backup Battery Compartment

The backup battery is not rechargeable, but in normal use, it should have enough charge to last for a year or more. Follow the guidelines below to maintain the backup battery:

Whenever the main battery pack is fully discharged, recharge it at the earliest opportunity.

If you have two main battery packs, try to always keep a charged battery inside your Compaq Palm-size PC. When you exchange the battery packs, make sure the device is without a main battery pack for just a short period of time.

If you will not be using your device for several days or more, first back up your data to your computer, then make sure that the battery pack is charged by keeping the device connected to AC power.

CAUTION: Failure to keep the main battery charged, or the Aero 2100 connected to AC power, can cause the backup battery to discharge and the eventual loss of data stored in RAM memory.
