What are the precautions for using mobile phone batteries?

Precautions for the use of mobile phone batteries 1. There has never been a unified statement about the activation of lithium batteries about whether it takes 12 hours for a new mobile phone to be purchased. Regarding whether a new mobile phone needs to be charged for 12 hours after the purchase, we hereby remind all netizens: The lithium battery of the new mobile phone is currently shipped from the factory and not long, there is no need to charge and activate for a long time, just use the normal method. . 2. Keep away from high temperature environment, do not use the phone in high temperature. Experts pointed out: Generally, it is the battery cell that causes the explosion of mobile phone batteries. The positive and negative poles of the battery cell should be covered with a layer of heat insulation film, and there is an auxiliary protection circuit to improve safety. If the battery design is unreasonable or the processing manufacturer cut corners, such as the heat resistance of the heat insulation film used is not enough or there is no protection circuit at all, the battery is overcharged or discharged or is affected by the external high temperature, it is easy to short-circuit and break through The shell exploded. In addition, placing the phone next to high temperature or flammable objects may also cause an explosion. 3. The battery is damaged. Don't continue to use it. I can also find that some friends, in order to save trouble, have obviously bulged up the battery and continue to use it in the phone. It is too dangerous. Regarding the lithium battery that has passed its service life (1-2 years), the performance of the battery has been greatly reduced, and the protection circuit may be aging. Consumers should stop using it immediately and replace it. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
