Backup Battery
The MX3X has a backup battery that is designed to provide limited-duration electrical power in
the event of Main Battery Pack failure. The Backup Battery is a 50 mAh Nickel Cadmium (NiCd)
battery that is factory installed in the unit. The need for recharging of the backup battery is
automatically detected and controlled by the MX3X. The energy needed to charge the backup
battery comes from the Main Battery.
It takes several hours of operation before the Backup Battery is capable of supporting the
operation of the computer. The duration of Backup Battery life is dependent upon operation of the
MX3X, it’s features and any operating applications.
The backup battery is replaced by LXE.
Note: An uninterrupted external power source (wall AC adapters or DC/DC converters)
transfers power to the MX3X internal charging circuitry which, in turn, recharges the
Main Battery and Backup Battery.
About Lithium-Ion Batteries
Li-Ion batteries (like all batteries) gradually lose their capacity over time (in a linear fashion) and
never just stop working. This is important to remember -- the MX3X is always 'on' even when in
the Suspend state and draws battery power at all times. Use the
Start | Settings | Control Panel |
Power | Battery
tab to check the battery status and power reading.
Always replace the used Main Battery with a fully charged Main Battery. The Battery Low
Warning LED illuminates red at approximately 35% of power left in the Main Battery. You need
to determine the point at which battery life becomes unacceptable for your business practices and
replace the Main Battery pack before that point.
Maintenance
Note: Make sure there is a fully charged main battery in the MX3X
before
running the Backup
Battery Discharge Utility. The backup battery can be discharged and charged while the
MX3X is receiving external power through the Power Jack or from a powered cradle.
The NiCd backup battery should be discharged completely once or twice a year. The Main Battery
Pack will fully charge the backup battery. This process will allow longer life for the Backup
Battery.
The backup battery is discharged by selecting
Control Panel | Battery
and clicking the
"Discharge" button. The discharge utility shows the progress of the discharging. At this time, the
program can be exited while continuing the discharge process. Normal use of the MX3X can
resume during the discharge, with the exception of Hot-Swapping the Main Battery. When the
backup battery is fully discharged, the MX3X will automatically stop the discharge process and
begin to recharge the backup battery.
DO NOT REMOVE THE MAIN BATTERY PACK from the MX3X until the backup battery is
completely discharged -- in approximately 1 hour and recharged in approximately 2.5 hours.
