How long will my notebook battery can last?

Notebook Battery

Notebook battery will decrease with time if you use them or not. Although Li-Ion battery industry does not publicize this fact, your battery's clock starts ticking the moment assembled. Elements within the battery will react, and eventually the battery will not be able to supply sufficient power for your notebook. In addition, your battery is designed to last between 300-800 cycles charge / recharge. And will gradually decrease its ability to supply power to the notebook.

In general, notebook battery will last between one to three years. You might be able to slow the decline in ability, but can not stop the process. Battery temperature, the manner and frequency of use of the notebook will affect the battery's lifespan. You can slow this process with some care and maintenance.

Temperature

Low temperatures will slow the process of discharge (lose charge while connected to AC power) and the aging process of the elements within the battery. Conversely, the high temperature will shorten battery life. Leaving your battery when connected to AC power causes the temperature of the battery increases. Remove and store the battery at cold temperature will slow the aging process. Keeping your notebook in a hot environment is also not good for batteries.

Usage

Lithium-Ion batteries used in notebooks are designed to be used about 300-800 times the charge / discharge cycles. Some of these cycles are used when you leave your battery installed when the notebook on AC power. On AC power, the notebook will routinely remove the battery when it reaches the level of knowl-charge's specific (ie 95%). Removing the battery and store in a cool dry place and will protect a few cycles.

User habits

Li-Ion Battery is not affected by memory effect (= battery needs to be used until completely discharged before recharging to avoid the reduction in capacity) like older rechargeable batteries. Recharge cycles full discharge will increase the loss of capacity per cycle. Some times the 'content-to-wear some' better than a one-time 'wear out'. However, you should also calibrate the battery regularly.
