This was said by a teacher at Kirill Sitnov at the Moscow School of Programmers (MSP). In his opinion, prolonged operation of the device with a “worn out” battery is undesirable. A swollen battery “sooner or later can depressurize and ignite.”
This leads to the use of non-genuine or low-quality batteries. Some batteries are also dangerous because they are made with increased capacity, but their standard dimensions are maintained.
According to the expert, you should avoid unverified service centers, because incorrect or poor-quality repairs can damage the controller responsible for the proper functioning of the battery. This may cause an explosion. Additionally, deformation can be a non-obvious cause of battery fire.
