Battery Packs

Storing a Battery Pack

If a computer will be unused and unplugged for more than two weeks, remove and store the battery pack.

ÄCAUTION: To prevent damage to a battery pack, do not expose it to high temperatures for extended periods of time.

To prolong the charge of a stored battery pack, place it in a cool, dry place. High temperatures cause a battery pack to lose its charge more quickly, thus reducing battery life.

The recommended storage temperature range is from 32°F to 86°F (0°C to 30°C).

Recycling a Used Battery Pack

To determine if the battery pack program is available in your geographical region, refer to the Regulatory and Safety Notices guide on this CD. If your region is not covered, refer to the Worldwide Telephone Numbers guide included with the computer and contact your Compaq authorized dealer, reseller, or service provider.
