Removing the 3-Cell Primary Battery
Remove the 3-cell primary battery by following the instructions in the section, “Removing the
Existing Primary Battery” earlier in this document.
Charging the Battery
Charge the primary battery and secondary battery (if any) by simply connecting your NEC
system to an AC power source. To monitor the charging activity, observe the battery charging
LED on the front of the system. The battery charging LED lights as follows:
!Lights amber when the primary battery is charging.
!Blinks amber if the primary battery encounters an error while charging.
!Lights green when the secondary battery is charging.
!Blinks green if the secondary battery encounters an error while charging.
During charging, keep the environmental temperature between 32°F
and 104°F (0°C to 40°C).
For directions on getting a detailed battery status, see the section, “Determining Battery Status.”
Determining Battery Status
Your NEC Versa system provides tools to help you keep track of the primary and secondary
battery power level. If your system is configured (default setting) to display the Power icon on
the taskbar, an electrical plug appears when the system is connected to an AC power source or a
battery icon displays when the system is not connected to an AC power source.
Use the system’s power meter to determine battery status. Access the system’s power meter in
the following ways:
!Move the cursor over the Power icon on the taskbar to display the remaining battery power
for the system’s primary battery.
!Right click the Power icon on the taskbar to open the power meter or to adjust power
properties.
!Double click the Power icon on the taskbar to display the remaining power for both the
primary and secondary battery (if any).
!Go to Start, Settings, Control Panel, and double click the Power Management icon and
select the Power Meter tab.

General Battery Precautions
To prevent accidental battery ignition, rupture, or explosion, adhere to the following
precautions.
There is a danger of explosion if the battery is incorrectly replaced.
Replace only with the same or equivalent type recommended by the manufacturer. Discard used
batteries according to the manufacturer’s instructions.
To avoid personal injury and property damage, read these battery precautions on handling,
charging, and disposing Li-Ion batteries.
!Keep the battery away from heat sources including direct sunlight, open fires, microwave
ovens, and high-voltage containers. Temperatures over 140º F (60ºC) may cause damage.
!Do not drop or impact the battery.
!Do not disassemble the battery.
!Do not solder the battery.
!Do not puncture the battery.
!Do not use a battery that appears damaged or deformed, has any rust on its casing, is
discolored, overheats, or emits a foul odor.
!Keep the battery dry and away from water.
!Keep metal objects away from battery connector. Metal objects in contact with the connector
can cause a short circuit and damage.
If the battery leaks:
!If the battery leaks onto skin or clothing, wash the area immediately with clean water. Battery
fluid can cause a skin rash and damage fabric.
!If battery fluid gets into eyes, DO NOT rub; rinse with clear water immediately and consult a
doctor.
!Take extra precautions to keep a leaking battery away from fire. There is a danger of ignition
or explosion.
