Choosing the right battery for laptop: Part Two

Choosing the right battery for laptop: Part Two

The laptop battery life

A laptop battery in a laptop is aging faster than in other types of use, because of the heat. The use of a laptop's internal temperature rises to 45 ° C. The combination of high temperature and promotes the full state of charge Zellenoxydation, a circumstance which, if once present can not be undone.

The life expectancy of the Sony VGP-BPS8 battery when it is working with high ambient temperatures, is only half as large, such as in moderate 20 ° C or. If a laptop left in a parked car, made worse in the blazing sun, the situation also. All batteries suffer permanent capacity loss, due to high temperatures but lithium-ion is more affected than other battery chemistries.

Some Japanese computer manufacturers have introduced a number of notebooks, for which the Dell Latitude D600 battery is arranged outside, and is a part of the housing. This design increases the battery life because the battery operates at room temperature. Some models allow for different battery sizes in order to adapt them to various requirements.

Lithium-ion is well suited for laptop users who continually switch between fixed-power and XPS M1330 battery. This user profile meets primarily for sales, maintenance and medical personnel. Here are the reasons why.

With nickel-based batteries, the charger performs a full charge every time, when the portable device is connected to a fixed power. The Latitude D630 battery is charged until a signal arrives, indicating that the battery is full. This signal is either a voltage change or an increase in temperature. Due to the delayed reaction, a permanent capacity loss occurs caused by overcharge and high temperature. Lithium-ion only receives charge if the voltage is low.
