NEC Versa TXi 6-Cell Extended-Life Battery 1
NEC Versa TXi
6-Cell Extended-Life Battery
Congratulations on purchasing a 6-cell Extended-Life Battery (kit OP-570-74503) for your NEC
Versa®notebook computer! Install the Extended-Life Battery in the primary battery bay of the
computer, instead of the 3-cell primary battery that ships with your notebook computer. Like the
3-cell primary battery, the 6-cell Extended-Life Battery allows you to run your system when the
system is not plugged into a 120- or 240-volt, 50- or 60-Hz wall outlet. Use the 6-cell Extended-
Life Battery if you want to run your system on battery power for a longer time before you must
recharge the battery.
Before installing the battery be sure to read the information in this document about:

Removing the Extended-Life Battery
Remove the Extended-Life Battery using the same procedure that is used for the 3-cell primary
battery. See the instructions in the section, “Removing the Existing Primary Battery” earlier in
this document.
Charging the Battery
The Extended-Life Battery is the primary battery in your system. Charge a 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 Extended-Life Battery (primary battery) is charging.
!Blinks amber if the Extended-Life Battery (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 battery power levels. Track
power levels for the Extended-Life Battery (which is your primary battery) and the secondary
battery (if one is installed) using these tools. 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 and 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 Extended-Life Battery (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
Extended-Life Battery (the primary battery) and the 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.
Battery Disposal
The Extended-Life Battery is a lithium ion (Li-Ion) battery.
Do not place used batteries in your regular trash. The batteries must be collected, recycled, or
disposed of in an environmentally approved manner.
Contact your local waste management officials for other information regarding the
environmentally sound collection, recycling, and disposal of the batteries.
