When you connect the computer to an external power source, the battery light on the computer turns on. However, charging may not occur until the battery pack reaches normal operating conditions, which may take several minutes to an hour. When the battery pack reaches the normal temperature and charge level, it begins to charge. The battery light on the computer turns off when the battery pack is fully charged.

Storing Battery Packs

Battery packs self-discharge even when they are not being used. If the computer will be unused and disconnected from an external power source for more than two weeks, remove the battery pack(s). This will reduce the discharge rate and extend the battery life.

To prolong the battery charge of a stored battery pack, store it in a cool, dry place. The recommended storage temperature range is from -4°F to 86°F (-20°C to 30°C). High temperatures cause a battery pack to lose its charge more quickly and reduce the battery pack life.

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

IMPORTANT: To ensure battery gauge accuracy, fully charge, fully discharge, and fully recharge a battery pack that has been unused for more than 30 days.

Recycling Used Battery Packs

The battery pack recycling program provides a safe and easy method for disposing of used battery packs. To inquire whether the recycling program is available in your area, see the Compaq worldwide telephone numbers in the Preface of this guide.
