How long does the battery of a notebook?

The maximum load capacity of any battery will decrease with time and use. The speed with which the capacity decreases varies depending on the computer configuration, the model, operating system, the type of software used, configuration, power management, and other factors.

Factors contributing to the loss of battery capacity of the notebook

The power capacity of notebook batteries decreases over time. The way battery is used also affects your ability.

The battery cells suffer gradual loss of capacity and irreversible with each cycle of loading and unloading. This wear occurs faster when the temperature and discharge rate increase.
The battery power decreases even when the battery is left in a powered off.
During prolonged storage or unused time, the battery power may decrease to a low voltage level lower than recommended.
If you leave the fully discharged battery for a long time, you can make sure the battery is in a state of low voltage and unusable. Leaving the battery with a high level of charge in an environment of high temperatures for long periods of time also will accelerate the loss of capacity.
The use of software for graphics processing or high-definition video accelerates the loss of capacity. For example, 3D gaming reduce the total load capacity faster than word processing applications.

Before starting this step, turn the computer and see if there is an access door to the battery compartment. If no battery compartment, HP recommends the following practices: increase battery life of laptop hp

If you will stop using the computer for more than three months, discharge the battery to a level of 70% before storage. If you plan to keep for a long time, check the battery capacity every six months and then charge to a level of 70%. Always keep the equipment at a temperature between 20 ° C and 25 ° C (68 ° -77 ° F).
If you use the computer primarily with AC power, allow the battery to fully discharge and recharge once a month.
