Dell Latitude C500 - Manual (Page 78)

The battery’s self-test capability alerts you to battery conditions such as low charge.
The battery has a life span of around 400 discharge/charge cycles, provided it is charged at normal
room temperature.
Battery Usage
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. For information on conserving battery power, see "

Management Modes ."
When you activate suspend
mode (known as
standby in the Microsoft® Windows® 98 and Windows 2000
operating systems), the computer can run on a fully-charged battery for approximately one week.
If you are going to store the computer, disconnect all peripheral 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 you attempt to run
your computer from the battery.
