Intermec 6400 manual Backup Battery, Main Memory

SECTION 1 General Information

Backup Battery

Your hand-held computer contains a rechargeable nickel- metal hydride backup 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 recharge 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.
