Recharging Battery Precautions

Adhere to the following precautions when recharging the primary or secondary
battery.
T
Use only the NEC battery charger designed for your NEC Versa battery
type. Different NEC Versa models require different batteries and battery
chargers.
T
Charge the battery for the specified charge time only.
T
During charging, keep the environmental temperature between 32°F and
104°F (5°C to 35°C).
T
Read the instructions that came with the battery charger before charging
the battery.

Extending Battery Life

While on the road, it is important to be aware of the simple things you can do to
extend the life of the system's main battery. One way is to keep the brightness
setting on the panel low. Use the slide switch on the front of the panel
(12.1-inch TFT, SVGA panel only) or use the
control the brightness.

NEC VersaBay III Battery

The NEC VersaBay III battery provides an optional second Lithium-Ion (Li-Ion)
battery to use in your NEC Versa LX computer. Inserting a second fully charged
battery increases battery life to approximately 4 to 5 hours.
See the NEC CSD web site at http://www.nec-computers.com/ for details about
the NEC VersaBay III battery.

Internal Batteries

The twelve-cell Lithium-Ion (Li-Ion) battery provides the main power source in
your NEC Versa LX computer. See Chapter 9 for a list of battery specifications.
In addition to this battery, the CMOS battery and bridge battery also provide
system power.

CMOS Battery

This lithium battery provides battery backup and prevents data loss in the
system's complementary metal-oxide semiconductor (CMOS) RAM. This
memory area contains information on the system's configuration, for example
date, time, drives, and memory. The CMOS battery may discharge completely if
the NEC Versa notebook remains unused for approximately two months.
