Charge the battery after it is used up and avoid charging it too long.

No matter what kind of battery it is, lithium or hydrogen battery should be charged after it is used up (electric consumption is lower than 1%). This is the best way to avoid the memory effect. The lithium battery also have the memory effect, the difference is that the memory effect is a little smaller than nickel hydrogen battery. Not fully charge and dies charge the battery will cause the chemical property inconsistent, therefore will degrade the battery performance. Propose to deeply discharge the battery once several months in order to optimize the battery. The concrete method is forbid the functions of management of power of operating system and BIOS, supply power with the battery, keep using until the system shuts down. Then charge the battery until it is fully charged. Then resume power management of BIOS and operating system to set up.

A battery in a laptop ages more quickly than in other applications because of heat. During use, the inside temperature of a laptop rises to 45^oC (113^oF).The combination of high temperature and full state-of-charge promotes cell oxidation, a condition that cannot be reversedonce present. The batterys life expectancy when operating at high temperature is half compared to running at a more moderate 20^oC (68^oF) or lower. Leaving the laptop in a parked car under the hot sun will also aggravate the situation. All batteries suffer permanent capacity loss as part of elevated temperatures but lithium-ion is affected more than other batteries.

Some Japanese computer manufacturers have introduced a number of sub-notebooks in which the battery is mounted externally, forming part of the housing. This design improves battery life because the battery is kept at room temperature.Some models carry several size batteries to accommodate different user demands.

Lithium-ion is well suited for laptop users who continually switch from fixed power to battery use. This user pattern is typical for those in the sales,service and medical field. Here is the reason why:

With nickel-based batteries, the charger applies a full charge each time the portable device is connected to fixed power. The battery is put on charge until a signal is received indicating that the battery is full. This signal is in form of a voltage change or rising temperature. Because of the sluggish response, permanent capacity loss occurs caused by overcharge and elevated temperature. Lithium-ion only receives charge if the voltage is low.
