NEC Versa DayLite/UltraLite
3-Cell Removable Battery
Congratulations on purchasing a 3-cell Removable Battery (kit OP-570-74703) for your NEC
Versa®DayLite™ or NEC Versa UltraLite™ notebook computer!
NEC Versa DayLite and UltraLite notebooks use two rechargeable batteries: a non-removable
lithium polymer Internal Battery, and a lithium-ion Removable Battery. These batteries allow
you to run your system when the system is not plugged into a 120- or 240-volt, 50- or 60-Hz
wall outlet. When you run your system on battery power, both of these batteries are used to
power the system.
Before installing the battery be sure to read the information in this document about:

Charging the Battery
Charge the Internal Battery and the Removable Battery by simply connecting your NEC Versa
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 Internal Battery is charging.
!Blinks amber if the Internal Battery encounters an error while charging.
!Lights green when the Removable Battery is charging.
!Blinks green if the Removable 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 power levels of both the
Internal Battery and the Removable Battery. 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 system’s Internal 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
Internal Battery and the Removable Battery.
!Go to Start, Settings, Control Panel, and double click the Power Management icon and
select the Power Meter tab.
