To ensure a long lifespan of your laptop battery Apple has a few points for you to keep in mind: First of all take note of the operating temperatures (50° to 95° F or 10° to 35° C) and secondly keep the electrons moving! Apple uses a commuter as an ideal example, who uses his notebook on the train and then plugs it in at the office to charge. If you don’t commute, Apple recommends charging and discharging the battery at least once per month. Need a reminder? There you go (iCal event).
