Storing a user-replaceable battery (select models only)

CAUTION: To reduce the risk of 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

user-replaceable 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 user-replaceable battery (select models only)

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.

See the Regulatory, Safety and Environmental Notices for proper battery disposal. These notices are

located in the printed Getting Started guide.
