What to do if the lithium battery swells

1. Please do not continue to use a bulging battery. If there is a bulge, try to replace it with a new one as soon as possible. Try not to rely on certain methods taught online to continue using the battery. 2. Do not charge your phone when playing with it. Check the battery status regularly to avoid dangerous situations. 3. When charging, pay attention to the choice of charger. For example, the nominal charging voltage of the battery is 3.7 V and the limit voltage is 4.2 V. Try not to choose a charger that exceeds this voltage. It is best to keep the current constant. 4. Choose batteries produced by major manufacturers, so that the quality is relatively reliable. The main reason is that you need to pay more attention to the degree of battery damage caused by your usual usage habits. 5. If the cell phone battery has been charged and bulged, first use your fingers to find the gap in the battery (the back of the mobile phone battery is close to the mobile phone charging electrode and is a little soft when pressed). . Simply pierce a small hole with a needle and let the air inside escape.
