What are the precautions for using lithium batteries

Firstly, 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.
