Precautions for extending the capacity and life of lithium batteries

From the above, we can summarize the following points for attention that can extend the capacity and life of lithium batteries.
If you have been using an external power source to power your laptop for a long time, or if the battery level has exceeded 80%, immediately remove the battery. It is not necessary to fully charge the battery during normal charging, and it can be charged to about 80%. Adjust the power options of the operating system to set the power alarm to above 20%, and the minimum battery power should not be lower than 20% in normal times.
For small electronic devices such as mobile phones, disconnect the power cord (including the USB interface for charging functions) immediately after charging. Continued connection can damage the battery. You need to charge it frequently, but you don't have to fully charge the battery.
Whether it's for laptops or mobile phones, be sure not to let the battery run out (automatic shutdown).
If you want to travel, you can fully charge the battery, but if conditions permit, always charge the appliance.
Use a more intelligent and power saving operating system.
Usage Matters
First, keeping lithium ion batteries properly charged and discharged can extend battery life. Maintaining the charge of a lithium ion battery at 10% to 90% is beneficial for battery protection. This means that when charging the batteries of digital products such as mobile phones and laptops, there is no need to reach the maximum value.
Digital products equipped with lithium ion batteries that are exposed to sunlight or stored in hot cars are best left in a closed state because lithium ion batteries can accelerate aging if the operating temperature exceeds 60 degrees Celsius.
Lithium battery charging temperature range: 0-45 degrees Celsius, lithium battery discharge temperature range: 0-60 degrees Celsius.
Secondly, if the phone battery needs to be charged every day, the reason may be that there is a defect in this battery, or it should "retire".
For notebook owners, if the plug is plugged in for a long time, it is best to remove the battery (the high heat generated by the computer during use is detrimental to the notebook battery).
Third, in general, 50% electricity is best for lithium ion battery storage.
