Motorola ML910 - Manual (Page 75)

CAUTION:
1. Batteries in ML910 RUGGED NOTEBOOK are allowed to discharge (i.e., operate normally)
when the battery temperature is from –20 ° C (–4 ° F) to 60 ° C (140 ° F) and allowed to be
charged when its temperature is ranging from 0 ° C (32 ° F) to 45 ° C (113 ° F).
2. These batteries are not allowed to operate outside of this range. When the ML910 RUGGED
NOTEBOOK is operating at extreme temperature and the battery is out of the operating
range, an external power supplies is required to be connected to allow continued operation
of the ML910 RUGGED NOTEBOOK unit.
To charge the battery pack, connect the AC adapter to the computer and an electrical
outlet. The “Battery status indicator (
)” will light amber when the battery is charging,
and green when the battery is fully charged. The “Battery low” indicator will blink red
when battery capacity is below 10 percent.
It takes approximately 180 minutes (3 hours) to charge the battery pack when the
computer is off and 240 minutes (4 hours) to fully charge the battery pack when the
computer is on.
CAUTION:
After the battery has been fully recharged, do not immediately disconnect and reconnect the
AC adapter to charge it again. Doing so may reduce the life of the battery.
NOTE:
1. The battery level may automatically lessen due to the self-discharge process (0.21% per
day), even after the battery pack has been fully charged to 100%. This will happen whether
the battery pack is installed in the computer or not.
2. The discharge will be significantly higher if the pack is stored in the computer with no
external power connected.
Initializing the Battery Pack
You need to initialize the new battery pack before using it for the first time. New battery
packs are warehoused and shipped to customers only partially charged to ensure
maximum life when they are placed into service. The battery charging indicator above
the keyboard may blink red to indicate a low battery condition.
Initializing is the process of fully charging the new pack and may take several hours. The
battery charging indicator will glow green when the pack is fully charged.
1. Make sure the computer is turned off. Connect the AC adapter to fully charge the
battery pack. The AC indicator will illuminate (green) and the battery charging
indicator will glow amber.
2. After the battery pack is fully charged, the charging indicator will turn to green. You
may now turn on the computer.
NOTE:
The ML910 will recondition the battery as necessary on a scheduled basis. There is no need
for the user to do this manually.
