AC Adapter and Battery: Dell™ Latitude™ C800 User's Guide
About the AC Adapter
l You can connect the AC adapter with your computer either turned on or off.
l
The AC adapter works with electrical outlets worldwide. However, power connectors vary among countries. Before you use AC power in a
foreign country, you may need to obtain a new power cable designed for use in that country.
l
If the computer is connected to a Dell docking device, you can run the computer on AC power by connecting the AC adapter to the docking
device.
NOTICE: To avoid overheating the AC adapter when powering the computer or charging the battery, use the AC adapter in a
ventilated area, such as on a desktop or on the floor. Do not use the AC adapter in a poorly ventilated environment, such as inside a
carrying case.

About the Batteries
l A partially charged lithium- ion battery comes standard in the battery bay, and provides power when an electrical outlet is not available. Dell
recommends that you charge your battery to full capacity before using it to power the computer. For information on conserving battery power,
see "
Conserving Power ."
l To increase battery life, install a second battery in the modular bay.
l With a single fully charged, 8-cell lithium-ion battery, you can expect about 2 –4 hours of battery life; with two fully charged lithium-ion batteries,
4 –8 hours of battery life. Actual performance depends on the power management features and application programs you use.
l When two batteries are installed, the computer draws power from the battery with the higher capacity until both batteries are at the same
charge level. Then it draws power from both. The AC adapter first charges the battery in the battery bay.
l The integrated charge gauge lets you check a battery ’s charge before you insert it into the computer.

NOTE: If you are running your computer on AC power with a battery installed, the AC adapter charges the battery (if needed) and then
maintains the battery's charge.
CAUTION: Do not puncture, disassemble, or incinerate the computer's battery. The battery may present a fire or chemical burn
hazard if mistreated. Do not expose the battery to temperatures above 60° Celsius (C) (140° Fahrenheit [F]). Keep the battery
away from children. Handle damaged or leaking batteries with extreme care. If the battery is damaged, electrolyte may leak
from the cells and cause personal injury.
