How to make the lithium battery life of the notebook the longest?

"The more the lithium battery is discharged, the more the battery will be depleted," said Akron University, a professor of electrical engineering who helped NASA study extended battery life. "The more the battery is fully charged." The battery will also wear more. The lithium battery is preferably in the middle of the battery, so the battery life is the longest."

First, the excessively high and too low state of charge has the most adverse effect on the life of the lithium battery, and the number of charge and discharge cycles is secondary. In fact, most of the resellers that are sold on electrical appliances or on the battery can be recharged based on 80 percent of the discharge. Experiments have shown that for some laptop lithium batteries, the battery voltage often exceeds the standard voltage of 0.1 volts, that is, from 4.1 volts to 4.2 volts, then the battery life will be halved, and then increased by 0.1 volts, the life is reduced to the original 3 One of the points; a long-term low-power or no-power state will cause the internal resistance of the battery to move more and more, resulting in a smaller battery capacity. NASA's NASA sets the battery's power consumption on the Hubble Space Telescope at 10 percent of its total capacity to ensure that the battery can be recharged and discharged 100,000 times without having to be updated.

The power consumption of the battery on the Hubble Space Telescope is set at 10% of the total capacity, and the number of battery charge and discharge cycles can reach 100,000 times.

Second, temperature has a large impact on lithium battery life (mobile phones and other small electronic devices can be ignored). The environment below the freezing point may cause the lithium battery to burn out at the moment when the electronic product is turned on, and the overheated environment will reduce the capacity of the battery. Therefore, if the notebook does not take the battery out for a long time, the battery will be in the high heat of the notebook for a long time. More importantly, the battery will be in a state of 100% for a long time and will be scrapped soon (including me. This is the case with your own laptop battery.)

From the above, we can summarize the following points to ensure the lithium battery capacity and life:

You don't need to charge the lithium battery to 100% full charge, and don't use it. When circumstances permit, try to keep the battery's power near half full, and the smaller the charge and discharge, the better;

The GM Chevy Volt electric car is designed to force the battery to be maintained at 20% to 80%, while Apple's built-in battery may also use this method (including some other notebooks and electronics) to make the battery available. The number of charge and discharge cycles increases.

Do not use lithium batteries (especially laptop lithium batteries) for a long time while the device is using an external power supply. Even if your notebook is well cooled, a long-term 100% charge is equal to the murder of a lithium battery.

1. If you have used an external power supply to power your laptop for a long time, or if the battery power has exceeded 80%, immediately remove the battery of your notebook, do not need to fully charge the battery, and charge it to about 80%; adjust the power supply of the operating system. Option, adjust the battery alarm to more than 20%, the minimum battery level should not be lower than 20%, and it should be charged before dropping to 20%;

2. Small electronic devices such as mobile phones should be disconnected immediately after charging the power cable (including the USB interface for charging function), which will damage the battery; it should be charged frequently, remember to charge, but do not have to fill the battery;

3. Do not let the battery run out, whether it is for a notebook or a mobile phone.

4. If you want to travel, fully charge the battery, but please remember to charge the appliance whenever possible, for battery life, do not wait until the battery is dry;

5. Use a smarter, more power-efficient operating system, such as genuine Windows 7.

Today, people have a lot of electronic devices, and a large part of them use lithium batteries to ensure that battery life is very practical. After all, the battery is scrapped and recycled, otherwise it will cause serious pollution to the environment.
