Introducing the MobilePro 2-11
If you receive a message indicating that the
main battery is very low, immediately connect the AC adapter to charge
the battery.
You cannot use your MobilePro when the battery lock is in the unlocked
position. The system displays an error message.
The battery does not charge when the battery lock button is in the
unlocked position.
Recharging the Main Battery Pack
The main battery pack contains rechargeable lithium ion cells.
Recharge a battery pack when you see the following message
displayed on your screen:
Main Batteries Very Low
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 MobilePro is connected to an AC power source.
The LED status is displayed as follows:
! Lights amber while charging.
! Lights green when fully charged.
It takes approximately 5 hours to recharge a fully depleted battery pack
regardless of the systems power state. However, if the main battery
has been depleted for a prolonged period, you must allow 6 to 10 hours
for the main battery to fully recharge.
Note Through normal use, the capacity of a battery pack gradually
declines. Should you notice that the battery does not stay charged as
long as expected, it is probably necessary to replace the main battery
with a new one. Please see Replacing the Main Battery later in this
chapter. Depending upon use, a battery pack should recharge from full
depletion approximately 300 times during the life of the battery.
