Introducing the NEC MobilePro 2-11
Recharging the Backup Battery
The backup battery charges while the main battery is charging. It usually
takes approximately 4.5 hours to recharge both the main and backup
batteries together.
A full 10 hours charging time is required under either of these
circumstances:
! This is the first time you have used your MobilePro
! The main battery has been in a depleted state for a prolonged period.
In these cases allow 10 hours for both the main and backup batteries to
charge, even if the LED indicator on the front of the MobilePro lights
green before the full 10 hours have passed.
To protect your data, do not use the system until the backup battery is
charged.
To recharge the main and backup batteries, connect the AC adapter. See
the section, “Connecting the AC Adapter” in Chapter 1.
MobilePro Power Management
When your MobilePro is connected to an AC power source and the main
battery is removed from the system, be sure to replace the main battery
before disconnecting the AC adapter to prevent possible data loss.
The MobilePro's internal data backup battery
provides power to maintain the memory contents for a limited period of
time when the main battery is removed and the unit is not connected to an
AC power source. The backup battery does not provide sufficient power to
operate the system.
Do not remove the main battery from the unit for an extended period of
time unless the unit is connected to an AC power source. The backup
battery is not user-replaceable.
