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; do not short external contacts; do not dispose of in fire or water.
Refer to the Regulatory, Safety and Environmental Notices for battery disposal information. These notices are located in the printed Getting Started guide.
