Can lithium batteries still be used even if they are swollen.

It is not recommended to continue using lithium batteries that have become swollen

Because during the process of lithium battery bulging, the capacity of the battery pack has decreased, and the standby time has significantly shortened. In severe cases, the standby time may be particularly short, and even calls cannot be made, causing problems such as restarting as soon as a call is made. And if the lithium battery continues to be used after bulging, it may cause an explosion when it expands to a certain limit, which is very dangerous. For safety reasons, it is best to replace the lithium battery with a new one in a timely manner when there is a bulge problem.

There may be two reasons for lithium battery bulging: first, there are issues with the manufacturing level of the battery, such as uneven electrode coating and rough production process; The second issue is overcharging and over discharging during use. If multiple batteries are bulging, it may be because the cut-off voltage of the charger used does not match the battery, and it is recommended to replace it. In addition, prolonged use of the battery can also cause bulging, as air is conductive to a certain extent. Prolonged discharge is equivalent to direct contact between the positive and negative poles of the battery, causing a chronic short circuit. Therefore, the battery should not be used again after being bulged, and a new battery should be replaced as soon as possible.
