Shanghai Haibao Battery Co., Ltd. is a battery manufacturing enterprise with a long history, formerly known as Shanghai Qiyi Battery Factory, established in the 1960s. The enterprise has long been committed to the in-depth research and development of electric vehicle power battery, and in 1993, it founded Shanghai Haibao special power supply Co., Ltd. becoming China's first research and development enterprise of electric bicycle battery. Through the cooperation and technical innovation and development of Shanghai No. 2 Bicycle Factory and "Haibao" people, the first electric bicycle  and the first electric bicycle  battery - Haibao battery were manufactured in China. Because of the leading demonstration effect of Haibao battery technology development, a few years later, cadmiferous electric bicycle  batteries of other brands came into the market one after another.

Haibao battery has been always adopting cadmium-free technology. The core technology of lead-calcium complex alloy researched and developed by "Haibao" represents the international advanced level, Haibao is worthy of the title --- one of the inventors of the world cadmium-free power battery. Haibao battery is recognized and highly trusted by electric bicycle manufacturers, dealers and consumers due to its stable performance and excellent quality, and becomes the representative of high-quality power battery products in the industry and market. For decades, Haibao battery strives for perfection and goes ahead steadily and surely, creating the miracle of the industry: the price is higher than that of well-known brands in the same industry, but it is still favored by the consumers due to its superior price performance ratio and the demand exceeds supply. Its excellent quality is always consistent under the witnessing of the history of more than 30 years.

Haibao has an advanced starting point. In 2014, the state implemented compulsory cancellation of cadmiferous battery, while "Haibao" has laid its technical development status in the industry since its inception, after decades of accumulation and historical witnessing, its cadmium-free technology is still leading in the field of power battery technology and continues to act as the industry’s technical standard to drive the development of the industry. With advanced technology and high-end quality, the return rate of Haibao battery is less than half of the return rate in the industry, truly achieving the minimum return rate in the industry and minimizing the worries of the consumers and dealers.

In 2012, Shanghai Haibao Battery Co., Ltd. successfully cooperated with Hong Kong Suzhong Group. With a total investment of RMB 1 billion Yuan, the new production base is located in Jiangsu Rudong Economic Development Zone. Relying on the strong power of Suzhong Group and the technical and management advantages of Haibao, it will provide consumers with the most up to date and best "Haibao" battery, and it will be committed to building the global No. 1 brand of power battery.
