　　18650 lithium battery maintenance method

　　1. The metal surface of the lithium battery that has been used for a long time will be oxidized to a certain extent, resulting in poor contact between the mobile phone battery and the mobile phone. , so that the contact between the battery and the phone becomes better.

　　2. Remove the lithium battery, put it for about a week, and consume the electricity slowly. You need to use the machine to completely consume the electricity first. Then charge it fully again. It is estimated that your current charging time must be very short. After it is fully charged, disconnect it and charge it again, and repeat it several times.

　　3. Let the near-end-of-life lithium battery be completely discharged, and then recharge to activate the battery. The specific method is: deeply discharge the mobile phone, that is, to achieve a deeper recharge by exhausting the internal power, which requires some unconventional methods.

　　4. Low temperature can change the electrolyte inside the lithium battery and promote the chemical reaction of the battery that has just been frozen. When the lithium battery is placed in a low-temperature environment, the microstructure of the lithium film on the surface of the lithium battery and the electrolyte, as well as their interface, will change significantly, resulting in temporary inactivity inside the battery and a decrease in leakage current. So after recharging, the standby time will increase.
