How to prolong the life of lithium battery capacity -Lithium - Ion Battery Equipment
The longer a lithium-ion battery is discharged, the more it wears out, said Tom Hartley, a professor of electrical engineering at the University of Iowa. The more you charge the battery, the more likely it will wear out. Lithium-ion batteries work best during charging because they have the longest battery life.
First, high and low charge states have the greatest negative impact on the life of Li-ion batteries, followed by the number of charge and discharges. In fact, most appliances or batteries are charged at an 80% discharge rate. Tests have shown that for some laptop lithium-ion batteries, the battery voltage is usually 0.1 volts higher than normal, rising from 4.1 volts to 4.2 volts, the battery life is halved, and adding 0.1 volts reduces battery life by a third. A long period of low power consumption and no power consumption will make the battery more resistant to the movement of electrons, resulting in a smaller battery capacity. NASA has set the Hubble Space Telescope's battery consumption at 10% of its total capacity so it can go through 100,000 charges and discharges without updating.(Lithium - Ion Battery Equipment)

Second, temperature has a significant effect on the life of Li-ion batteries (negligible in cell phones and other small electronic devices). Sub-freezing conditions can cause lithium-ion batteries to burn out when the electronics are turned on, while overheating conditions reduce battery capacity. Therefore, if the pen power is used for a long time using external power supply will not take the battery down, the laptop battery discharges high temperature temporarily for a long time, and more importantly, the battery is at 100% power position for a long time, soon will be out of date.
In summary, we can summarize the following points for attention to ensure the capacity and life of lithium-ion batteries:
Lithium-ion batteries, which are used in most electronic products, have grown rapidly since their introduction in 1990 and are widely used by lithium-ion battery manufacturers. You don't have to fully charge the Li-Ion battery, and don't worry about running out. When the situation allows, try to keep the battery power near half full state, the less the charge and discharge fluctuations, the better;
The Chevy Volt is designed so that the battery must hold between 20% and 80% charge, and the same approach can be used with Apple's built-in battery (and some other laptops and electronics) to increase the number of battery charge and discharge cycles.
Do not use lithium-ion batteries (especially laptop batteries) for extended periods of time when the device is powered by an external power source. Even if your laptop is well-cooled, prolonged use at 100% will kill the Li-Ion battery.
1. If you use an external power supply to power the laptop for a long time, perhaps the battery power has exceeded 80%, please remove the battery of the laptop immediately. Generally, do not charge the battery, and charge it to about 80%; adjust the operating system. Power options, set the power alarm above 20%. The minimum power of the battery should not be less than 20%.
2. Regarding small electronic devices such as mobile phones, the power cord (including the USB port for charging) should be disconnected immediately after charging, which tends to damage the battery; charge it frequently. Charge it when you remember, but you don't charge it.
3. Make sure your laptop or phone's battery doesn't drain.
If you're going on a trip, charge the battery, but remember to charge the appliance at any time when conditions permit, and for battery life, don't let it dry compared to the battery.
