Lithium battery usage

First, keeping lithium-ion batteries charged and discharged moderately can extend battery life. Maintaining the power of lithium-ion batteries at 10% to 90% is beneficial to protecting the battery. This means that when charging the batteries of digital products such as mobile phones and laptops, it is not necessary to reach the maximum value.
Digital products equipped with lithium-ion batteries are exposed to sunlight or stored in hot cars. It is best to turn off these products because lithium-ion batteries will accelerate aging if the operating temperature exceeds 60 degrees Celsius.
The charging temperature range of lithium batteries is 0 to 45 degrees Celsius, and the discharge temperature range of lithium batteries is 0 to 60 degrees Celsius.
Second, if the mobile phone battery needs to be charged every day, the reason may be that the battery is defective or it is time for it to be "retired".
For laptop owners, it is best to remove the battery if it is plugged in for a long time (the high heat generated by the computer during use is not good for laptop batteries).
Third, under normal circumstances, 50% power is most conducive to the preservation of lithium-ion batteries.
