NEC Versa DayLite/UltraLite
3-Cell Removable Battery
Congratulations on purchasing a 3-cell Removable Battery (kit OP-570-74703) for your NEC
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:
