About the Batteries
Your computer includes a standard (34-watt/hour [WH]) or high-capacity (46-WH) lithium ion battery that provides power when an electrical outlet is
not available. The battery is installed on the underside of the computer and forms part of the bottom of the computer. Lithium ion batteries are
longer lived than conventional batteries and do not require replacement as often. Lithium ion batteries do not have the memory effect that is
exhibited by nickel-metal hydride (NiMH) and nickel-cadmium (NiCD) batteries. You do not need to drain a lithium ion battery completely before
recharging it. A lithium ion battery will not forget at which point it is fully charged. NiMH and NiCD batteries may not charge fully if they are partially
drained then recharged.
Do not place spent batteries with common household waste products. Contact local authorities for the location of a chemical waste collection
program nearest you.
Keep the following information in mind when you are running your computer from the battery:
l
From a fully charged standard battery you can expect between 2.5 and 3 hours of battery life; from a fully charged high-capacity battery, you
can expect up to 50 percent greater battery life. Actual performance varies, depending on which power management features are enabled
and which application programs you are using.
l
The integrated battery charge gauge lets you check the charge status of an installed or uninstalled battery at any time.
l
The battery
’
s self-test capability alerts you to battery conditions such as low charge.
l
There is no battery memory effect with lithium ion batteries — you can charge the battery whenever you like without fear of reducing its
charge capacity.
l
A battery has a life span of up to 350 full charges and 2000 partial charges, provided it is charged at normal room temperature.
Using the Battery
The battery is partially charged when you receive it. Dell recommends that you charge your battery to full capacity before using it to power the
computer.
If you are powering the computer from a battery, try to conserve battery power. A number of factors affect battery operating time:
l
Power conservation features that you use
l
Type of display and microprocessor installed
l
Use of storage media
l
Number and type of PC Cards and other external devices that you use
l
Kinds of application programs that you run
l
Capacity of the memory modules that you install (the higher the capacity, the more power used)
When you activate suspend mode (known as standby in the Microsoft ® Windows ® 98 operating system), the computer can remain in suspend
mode on battery power for approximately one week (if the battery was fully charged before activating suspend or standby mode).
If you are going to store the computer, disconnect all devices and turn off the computer. Remove the battery when you store your computer for an
extended period of time. A battery will drain when not in use during prolonged storage. After a long storage period, recharge the battery fully before
