With the improvement of people's living standards, mobile devices such as laptops, tablets, digital cameras, navigation devices, mobile phones, MP3 players, etc. have become essential items in people's lives. These mobile devices are powered by lithium batteries, and the battery life of lithium batteries is the most concerned issue for people. The maintenance of lithium batteries is the most critical.

        Taking laptops as an example, besides system power consumption, the maintenance of lithium batteries is also one of the main factors affecting the battery life of laptops. Otherwise, you need to frequently replace external or backup batteries.

        Recently, An article on the Battery University website on how to extend the life of lithium-ion batteries proposes a new conclusion on the best maintenance of lithium-ion batteries: the best maintenance method for lithium-ion batteries is light use, fast discharge and fast charging, which is similar to the use of mechanical equipment. The higher the frequency and frequency of use, the faster the battery will wear out. The smaller the degree of deep discharge of lithium batteries, the longer their usage time. If possible, try to avoid frequent full charging and discharging.

        For users, it is best to charge your lithium battery when it has been used for 10% or 20%. You can also charge it when the remaining battery is at 50%, but try to avoid starting charging when your phone prompts that the battery is low. Under no circumstances should you run out of battery power. If going out, try to use larger capacity batteries or portable power banks.

        In addition, the temperature of the usage environment also has an impact on the lifespan of lithium batteries. Temperatures that are too high (30 ℃) or too low can cause damage to the lifespan of lithium batteries. For example, for laptops that are frequently connected to adapter power, it is best to remove the battery. In fact, this does not cause damage to the battery during charging, as the battery will no longer charge after being fully charged. However, when using a laptop, not paying attention to the ventilation at the bottom can cause overheating, which is the real culprit affecting battery life. Of course, if there is a good usage environment or cooling base, lithium batteries can prevent the loss of unsaved data during power outages.

        The maintenance of lithium-ion batteries may not have a significant impact on a single charge discharge cycle, but over time, there will be a comparison. After using lithium-ion batteries for a year or more, the battery capacity will be lost, and well maintained lithium-ion batteries will have much better loss situations.
