Battery Disposal

Before disposing of the main battery, put adhesive tape on
the terminals. The main battery is made of either Nickel
Metal-Hydride (NiMH) or Lithium Ion (Li-Ion).
Contact your local waste management officials for infor-
mation regarding environmentally sound collection, recy-
cling, and disposal of batteries.

INTERNAL BATTERIES

Your nickel metal-hydride or lithium Ion battery is the main
power source in your NEC Versa 2600 computer.
Appendix B lists NiMH and Li-Ion battery specifications.
In addition to this battery, the CMOS battery and bridge
battery provide power for system backup.

CMOS Battery

This 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 lasts approximately two
years.
Only an authorized NEC service technician can replace the
CMOS battery.

Bridge Battery

The bridge battery provides power to the NEC Versa 2600
when main battery power is very low (and the system is
about to shut down), and during the time a spent main bat-
tery is removed and replaced. The bridge battery gives you
time to

Save your unsaved data, close your open programs, and
