Storing a user-replaceable battery
CAUTION: To reduce the risk of damage to a battery, do not expose it to high temperatures for

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.

an HP warranty, instructions include a warranty ID. A message refers you to the HP website for more
