How to extend APPLE laptop battery life? Here are some more tips to improve your APPLE notebook's battery life:

1. If you do not use your laptop for extended periods of time (a week or more), remove the apple laptop battery pack from the laptop.
2. Do not expose the battery to high heat or freezing temperatures. Do not leave your battery in your car in the summer. Hot batteries discharge very quickly, and cold ones can't create as much power.
3. Make sure to plug your laptop charger adapter into a UPS and not directly into a power outlet or surge protector.
4. If you have a nickel-metal hydride battery, completely drain and recharge the battery once a month to maximize its capacity to hold a charge.
5. Fully charge new battery packs before use. New pack needs to be fully charged and discharged (cycled) a few times before it can condition to full capacity.
6. For laptops that work as Desktop Replacement, the battery should be re-installed every 3-4 weeks and allowed to fully discharge.
7. Leaving a battery in a laptop while using an electrical outlet for long periods of time will keep the battery in a constant state of charging up and that will reduce the life cycle of the battery.
