Mengingat battery baru perlu perawatan ektra, saya search google tentang tips perawatan battery Li-Ion agar awet. dan menurut url http://www.laptop-battery.org/batterytips.html caranya sebagai berikut :

  1. New battery pack must be fully charged before use.

  2. New battery pack needs to be fully charged and discharged (cycled) a few times before it can condition to full capacity.

  4. Fully drain and fully recharge your battery pack every few month.

  5. Turn down the LCD brightness of your portable device.

  6. Use built-in power management on your portable device.

  7. Turn off LCD or other unnecessary accessories when not in use.

  8. Set screen saver blank to 1 to 2 minutes of your notebook

  9. Add more RAM if you have extra RAM expansion slot, it will reduce the usage of hard drive and it is power exhaustive.

  10. Close unused software in your notebook.
