The repair scheme is only applicable to the case of battery water shortage!
Our company has been focusing on battery repair 10 for many years, and the founder, Mr. Xu Changhong, has obtained many national patents on battery repair!
It takes 2-5 days for us to maintain a battery normally. Don't trust online battery maintenance videos, and don't operate them yourself. Please go to a regular battery repair shop for repair, so as not to scrap the battery!
