System Batteries
Your NEC Versa notebook is equipped with a primary lithium ion battery that helps to
prevent data loss. In addition, you can install an optional secondary lithium ion battery
pack on the bottom of your NEC Versa to give you more on-the-go power.
Primary Battery
The standard lithium ion (Li-Ion) battery provides the main power source when you are
operating the NEC Versa notebook on battery power. Your system comes with a 4-cell
lithium ion battery in the battery bay on the bottom of your system. See Appendix B for
battery specifications.
For information about installing or removing the primary battery, see the section,
“Replacing the Battery” later in this chapter. For more information about the primary
battery see the section, “Using the Primary Battery.”
Note
See “Windows Power Management” in Chapter 4 to fully utilize battery power
in your NEC Versa notebook.
Secondary Battery
You can install an optional secondary lithium ion battery on the bottom of your NEC
Versa notebook. This is a very thin battery pack that covers the bottom of the unit.
Attaching a second fully charged battery allows you to work longer while you are away
from an AC power source.
For more information about the secondary battery, see the section, “Using the
Secondary Battery” later in this chapter. For information about installing a secondary
battery, see “Secondary Battery” in Chapter 5.
