How i must to-do with Li-ion Laptop Battery

Li-ion or Lithium Ion are often used in newly produced laptop and mobile device. Actually i wrote about Laptop Battery Maintenance before, it's about how to maintain your laptop battery by doing regular fully cycle (fully charge and then fully discharge). But, later i know that those methods are only work on Ni-Cad and Ni-Mh battery.

A fully cycle don't work for Li-ion battery, even worse fully discharging Li-ion battery may shorten battery life, as this puts additional strain on the battery. Keep the li-ion battery cool, avoid a hot car and keep the battery at a 40% charge level.

Don't worried about over-charged the battery since Li-ion battery don't have memory effect. Memory effect means that if a battery is continually only partially discharged before re-charging, the battery “forgets” that is has the capacity to further discharge all the way down. Beside, Li-ion has a built in smart protective circuit  (charge control) which will keep monitoring charging process. After the battery is fully charged, current flow to the battery is stopped by a built-in smart protective circuit. The protective circuit prevents the battery from being charged or discharged beyond safe limits.
