Battery Packs Calibrating a Battery Pack When to Calibrate Calibrate an in-use primary or MultiBay battery pack whenever battery status displays seem inaccurate or whenever the battery pack has not been used for 1 month or more. It should not be necessary to calibrate any battery pack, even if it is heavily used, more than once a month. It is not necessary to calibrate a new battery pack before first use. How to Calibrate Calibration requires 3 steps: 1. Fully charge the battery pack. 2. Fully discharge the battery pack. 3. Fully recharge the battery pack. Charging the Battery Pack You can charge the battery pack while the notebook is in use or off, but the battery pack will charge faster while the notebook is off. To charge the battery pack: 1. Insert the battery pack into the notebook. 2. Connect the notebook to an AC outlet or an optional Automobile Power Adapter/Charger. (The battery light turns on.) 3. Leave the notebook connected to AC power until the battery pack is fully charged. (The battery light turns off.) 3-12 Hardware Guide
