Storing a Battery Pack
CAUTION: To prevent damage to a battery pack, do not expose it to
high temperatures for extended periods of time.
If the computer will be unused and unplugged from an external
power source for more than two weeks, remove and store the
battery packs.
Proper storage procedures reduce the self-discharge rate of a
battery pack. Store a battery pack in a cool, dry place within the
following temperature ranges.
Recommended Battery Pack Storage Temperatures
Storage Time Temperature Range °F Temperature Range °C
Less than
1 month
32°–122° 0°–50°
No more than
3 months
32°–104° 0°–40°
Unlimited 32°– 86° 0°–30°
Maximizing Battery Pack Life
Battery pack operating time varies depending on the system
components, options, and applications used. Battery operating
time can increase by as much as 50 percent by controlling the
energy used by the computer and the energy stored in the battery
pack.
NOTE: The display, processor, and drive components use the
majority of battery power.
To maximize battery pack life, use the following guidelines:
■ Select the High level of power management (not available
under Windows 98). See Chapter 5 for more information on
power management.
■ Initiate Suspend or Hibernation or turn the computer off when
you are not using it.
■ Reduce the display brightness and select a shorter screen save
timeout.
■ Keep a battery pack in the computer when you are using the
computer with external power.
