Storing a battery
CAUTION: To prevent damage to a battery, do not expose it to high temperatures for extended periods
of time.
If a computer will be unused and unplugged from external power for more than 2 weeks, remove the
battery and store it separately.
To prolong the charge of a stored battery, place it in a cool, dry place.
NOTE: A stored battery should be checked every 6 months. If the capacity is less than 50 percent,
recharge the battery before returning it to storage.
Calibrate a battery before using it if it has been stored for one month or more.
Disposing of a used battery
WARNING! To reduce the risk of fire or burns, do not disassemble, crush, or puncture a battery; short
the external contacts on a battery; or dispose of a battery in fire or water. Do not expose a battery to
temperatures above 60˚C (140˚F). Replace the battery only with a battery approved for this computer.
Refer to the Regulatory, Safety and Environmental Notices for battery disposal information.
