Should stop charging immediately, in the room, need to open the window ventilation. The battery also squeaks, indicating that the battery charging current is too large, or the charging time is too long, causing the battery to overcharge. The battery flushing drum is caused by the deformation of the battery plate and the extrusion of the battery shell, and the squeaking sound is a condition of the decomposition reaction of the electrolyte after excessive heat. The above situation indicates that the charging time is relatively long, or the charging current is relatively large, so it is recommended to reflect on these two situations and improve.
This situation is very dangerous and must be stopped immediately. The tricycle battery is filled with a drum, indicating that the battery has been damaged, it is because of the deformation of the battery plate caused by the battery drum, and the battery also squeaks, indicating that the battery has been in a state of overcharging, the chemical reaction is intense, the electrolyte is in a state of high temperature, squeaking, it is the electrolyte in the decomposition of a sound, if not timely power off, Go down there and there could be an explosion.
