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
install a second Lithium-Ion battery in the VersaBay III, extending battery life when
away from an AC power source.
Main Battery
The twelve-cell Lithium-Ion (Li-Ion) battery provides the main power source in your
NEC Versa LXi 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 an extended period of time.
Bridge Battery
The bridge battery saves your system status in Suspend (Windows 95/NT) or Standby
(Windows 98) mode, giving you time to install a fully charged battery or plug in 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 Battery
The NEC VersaBay III Battery Pack provides a optional, second Lithium-Ion (Li-Ion)
battery to use in your NEC Versa computer. Inserting a second fully charged battery
increases battery life for your notebook computer.
