System Batteries

Your NEC Versa is equipped with a main, Lithium-Ion battery and two backup
batteries that help to prevent data loss. In addition, your system provides the option to
attach a second Lithium-Ion battery to the connector on the bottom of the system,
extending battery life when you are away from an AC power source.

Main Battery

The standard Lithium-Ion (Li-Ion) battery provides the main power source in your
NEC Versa FX computer. See Appendix B 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 charges when your NEC Versa is connected to AC power. The
CMOS battery may discharge completely if the NEC Versa notebook remains unused
for approximately two months.

Bridge Battery

The bridge battery saves your system status in Standby mode giving you time to install
a fully charged battery or connect to AC power when your battery charge becomes low.
The bridge battery should be replaced only by an authorized NECC technician.
hours before using it on battery power for the first time. Doing so insures that the bridge
battery is fully charged and that no data is lost during a battery change.

Optional Batteries

Your NEC Versa FX system allows you to install an optional Extra Life Lithium-Ion
battery in the main battery bay. In addition, your system is equipped with a battery
connector on the bottom of the system, that enables you to attach an optional,
Maximum Life Lithium-Ion battery. Attaching a second fully charged battery increases
battery life while you are away from an AC power source.
