The battery life and aging

The battery life and aging

Rechargeable laptop battery have become an essential part of portable electronic devices. The following information will help you understand better how the battery performs.

There are three common types of rechargeable Dell XPS M140 Battery in portable electronic devices in use today: Nickel-cadmium (Ni-Cd), nickel-metal hydride (Ni-MH), Lithium Ion (Li-Ion). Most laptop batteries are lithium-ion batteries, so allow me some battery life of lithium-ion and aging.

Battery life depends on product configuration, product model, applications loaded on the product, power management settings, used the product and product features by the customer. as with all batteries, maximum capacity of the battery will decrease with time or use.

all batteries gradually lose their ability to hold a charge. The Dell XPS M1330 Battery life is the number of charge cycles and food materials before the battery can no longer hold a useful amount of cargo.

This loss in capacity (aging) is irreversible and can not be restored. Gradually, less and less active material is in each electrochemical cell are available to store a charge. Therefore, the battery provides less time for the power of the computer useful.

Lithium-ion (Li-ion) Dell XPS M1530 Battery usually have a lifespan of 300 to 500 cycles. With moderate use, Li-ion batteries can be expected to deliver approximately 80% of its original capacity after 300 cycles or about one year, see the use (chart).

Note: The above table shows the 80% of original Dell Latitude D820 Battery capacity after 300 cycles at an operating temperature between 77 ° C and 104 ° F (25 ° C and 40 ° C). Higher temperatures may be operating at 70% or more of the loss of function, the same number of cycles.
