Firstly, lithium-ion batteries are ubiquitous in people's lives, including various portable electronic products, car GPS, etc. Lithium ion batteries have become an important component for maintaining the operation of these tools. Maintaining moderate charging and discharging of lithium-ion batteries can extend battery life. Maintaining the charge of lithium-ion batteries at 10% to 90% is beneficial for battery protection. This means that when charging the batteries of digital products such as smartphones 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, as lithium-ion batteries can accelerate aging if the operating temperature exceeds 60 degrees Celsius. Lithium battery charging temperature range: 0-45 degrees Celsius, and lithium battery discharge temperature range: 0-60 degrees Celsius.

　　Secondly, if the mobile phone battery needs to be charged every day, the reason may be that this battery has a defect, or it should be "retired".

　　For laptop 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 laptop battery).

　　Thirdly, in general, 50% of the battery capacity is most conducive to the preservation of lithium-ion batteries.

　　Correct charging practices

　　In summary, the most important reminder for the charging and discharging issues of lithium batteries in use is:

　　1. Charge according to the standard time and procedure, even for new lithium batteries, the first three times should be done the same way;

　　2. When there is a low machine power prompt, it is advisable to start charging as soon as possible (do not wait for automatic shutdown);

　　3. The activation of lithium batteries does not require special methods, as they will naturally activate during normal machine use. If you insist on using the popular "first three 12 hour long charges" activation method, it will not actually have any effect.

　　Therefore, all practices that pursue 12 hours of ultra long charging and use single cell lithium batteries for automatic shutdown are wrong. If you have followed the wrong statement before, please correct it in a timely manner, perhaps it is not too late.
