The lifespan of a laptop is largely determined by its operating conditions and timely maintenance. Experienced users often recommend disconnecting the laptop battery when plugged in. To what extent is it advisable and does it harm the computer to work without an autonomous power source?
The most important argument that experienced users cite in favor of disconnecting the laptop battery during prolonged operation from the network is as follows: the battery installed on the device is constantly in recharge mode, which significantly reduces its service life.
However, in fact, the battery goes into recharging mode only when the level of discharge allowed by the design falls below 90-95%, and when operating from the mains, this does not threaten the laptop. A standard laptop battery is designed to function with an alternating cycle of charging and discharging.
In addition, the battery provides uninterrupted power to the laptop in the event of a power outage, which sometimes happens. Therefore, a battery inserted in its place when operating from an electrical network will allow you to save information in a timely manner and prevent data loss. Agree that this way you save not only time, but also peace of mind.
An additional counter-argument that shatters battery-free advocates is the fact that the laptop's main selling point is portability. The connected battery allows you to move to another place and continue working without unnecessary waste of time. If the battery is disconnected, then you will not only have to insert it into the slot, but also recharge for some time to bring the device into full readiness. Remember that a battery that is disconnected from a laptop is susceptible to self-discharge.
However, if you work in stationary mode for a long time, are sure of an uninterrupted supply of electrical voltage, or use a special surge protector that allows you to get additional time for an emergency shutdown, then you can easily disconnect the battery from the laptop. But this will practically not affect the life of the battery. Statistics say that the average battery life is no more than two to three years in any case.
