Backup Battery
Your hand-held computer contains a rechargeable nickel-
metal hydride back up battery. This backup battery re-
charges when needed from either an external charging
source (like a printer or dock) or from the main battery
pack. If the backup battery is completely run down it takes
a minimum of 8 hours to completely recharge but it is bet-
ter to r echarge it for a full 12 hours.
The backup battery remains ready to protect the computers
data whenever the main battery pack is removed or needs
recharging. The backup battery should last about 500
cycles (discharge and recharge equals a cycle). This battery
should last for about 5 years before it needs to be replaced.
If your computer fails to hold data for at least 100 hours in
the suspend mode, send your computer to the Intermec
Customer Support Center for replacement.
