How is the quality of Mohr's battery?

Very good.

According to the query on Baidu Youjia, we learned that the Mohr battery uses K2 double-cover technology. The K2 double-cover sealing design ensures that even if the battery is tilted greatly, there will be no acid leakage, preventing vehicle parts from being damaged. Sulfuric acid liquid corrodes to avoid driving safety hazards and allows you to travel safely. Once this technology is used, it has become a new standard for high-quality batteries.

Moll is a battery produced by a joint venture between Germany's MOLL and China's Chaowei. It has always been the top brand in the German automotive industry. Among the many advanced patented technologies of MOLL batteries, the invention of start-stop batteries has been particularly prominent in recent years.
