There are three types of electric vehicle battery voltages: 36 volts, 48 ??volts and 60 volts, which refer to the battery voltage. The current 12 amps and 20 amps refer to the battery capacity, 12AH and 20AH.

Lead-acid batteries are widely used and widely studied in various electric vehicles in various countries due to their comprehensive factors such as low price, abundant material sources, high specific power, mature technology and manufacturing process, and high resource recovery rate. As a labor-saving, convenient, fast, comfortable, cheap and zero-emission personal transportation method, electric bicycles have been widely accepted by people and have attracted the attention of relevant national departments.

The "Research on the Development Strategy of the Light Electric Vehicle Industry" project team participated by the Development Research Center of the State Council, the National Development and Reform Commission, the Ministry of Construction, the Ministry of Science and Technology and other ministries and commissions proposed a report on the "Research on the Development Strategy of the Light Electric Vehicle Industry." The number of electric bicycles nationwide has reached more than 30 million. More than 95% of electric bicycles use valve-regulated lead-acid batteries.

Purchasing method

1. Check whether the electric vehicle battery product logo is complete. Including the manufacturer name, product specifications and models, manufacturing date, and trademark; check whether the internal and external marks are consistent, especially check whether the product body has eye-catching logos and production dates.

2. Pay attention to the appearance of the electric vehicle battery. Check for deformation, cracks, scratches and signs of leakage. The battery terminals should be clean, free of rust, and clearly marked.

3. Pay attention to the rated capacity marked on electric vehicle battery products. The larger the rated capacity marked on the battery, the longer the battery discharge time. It is best not to buy batteries without rated markings, but pay attention to whether they are specially designed for electric vehicles.

4. Choose brand batteries from well-known companies and large companies. Batteries are generally provided by professional battery manufacturers. Batteries produced by different brands and manufacturers vary in quality and price. Well-known and large enterprises have large scale, strong technology, good after-sales service, and guaranteed battery quality.
