2-12 Introducing the NEC MobilePro
Recharging the Main Battery Pack
The main battery pack contains rechargeable Lithium-Ion
cells. Recharge a battery pack when the system displays a
low battery warning.
To recharge a battery pack installed in the battery bay,
connect the AC adapter. See “Connecting the AC Adapter” in
Chapter 1.
The battery charging LED indicates the charging status of the
main battery pack when the NEC MobilePro is connected to
an AC power source. The LED status displays a s follows:
Lights amber while charging.
Lights green when fully charged.
It takes approximately 4.5 hours to recharge a fully depleted
battery pack regardless of the system's power state. However,
if the main battery has been depleted for a prolonged period,
you must also allow time for the backup battery to fully
recharge (see the section, “Recharging the Backup Battery").
Note:
Through normal use, the capacity of
a battery pack gradually declines. Depending
upon use, a battery pack should recharge from
full depletion approximately 300 times during the
life of the battery. Should you notice that the
battery does not stay charged as long as
expected, it is probably necessary to replace the
battery with a new one. Please refer to the
section “Battery Replacement” later in this
chapter.
