Battery Packs Storing a Battery Pack If a notebook will be unused and not connected to external power for 2 weeks or more, remove and store the battery pack. Ä CAUTION: To prevent damage to a battery pack, do not expose it to high temperatures for an extended time. High temperatures accelerate the self-discharge rate of a stored battery pack. To prolong the charge of a stored battery pack, place it in a cool, dry place. Use the following table to estimate how long you can safely store a battery pack. The storage times provided are based on a battery pack that contains 50 percent of a full charge. A fully charged battery pack can be safely stored for longer times; a battery pack containing a lower charge can be safely stored for less time. Calibrate a battery pack that has been stored for 1 month or more before using it. Temperature Range (°F) Temperature Range (°C) Safe Storage Time 115° to 140° 79° to 113° 32° to 77° 46° to 60° 26° to 45° 0° to 25° Less than 1 month No more than 3 months 1 year 3-24 Hardware Guide
