The recommended storage temperature range is from 32°F to 104°F (0°C to 40°C). However, batteries can be stored at 32°F to 140°F (0°C to 60°C) for up to 30 days. CAUTION: To prevent damage to a battery pack, do not expose it to high temperatures for extended periods of time. Maximizing Battery Pack Life Battery pack operating time varies depending on the system components, options, and applications used. You can increase battery operating time 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: s Select the High level of power management (not available under Windows 98). See Chapter 5 for more information on power management. s Initiate Suspend or Hibernation or turn the computer off when you are not using it. s Reduce the display brightness and select a shorter screen save timeout. s Keep a battery pack in the computer when you are using the computer with external power. s Disconnect external equipment that does not have its own power source. (External equipment connected to the computer drains the battery pack.) s Exit modem programs when you are not using them. s Remove a PC Card when you are not using it. s When storing the computer for more than two weeks, remove battery pack(s) and store them separately to reduce the discharge rate and increase battery life. 4-8 Using Battery Packs

Using Battery Packs
The recommended storage temperature range is from 32°F to
104°F (0°C to 40°C). However, batteries can be stored at 32°F to
140°F (0°C to 60°C) for up to 30 days.
CAUTION:
To prevent damage to a battery pack, do not expose it to
high temperatures for extended periods of time.
Maximizing Battery Pack Life
Battery pack operating time varies depending on the system
components, options, and applications used. You can increase
battery operating time by as much as 50 percent by controlling the
energy used by the computer and the energy stored in the battery
pack.
NOTE:
T
he 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.
■
Disconnect external equipment that does not have its own
power source. (External equipment connected to the computer
drains the battery pack.)
■
Exit modem programs when you are not using them.
■
Remove a PC Card when you are not using it.
■
When storing the computer for more than two weeks, remove
battery pack(s) and store them separately to reduce the
discharge rate and increase battery life.
