The sail fully adopts the technical standards of the United States, Germany, Japan, France and its famous automobile manufacturers, and the product performance has reached the current international technical level. A number of battery special production lines and testing equipment have been introduced, with an annual production capacity of 3.5 million kVAh.
 
There are ordinary maintenance-free series batteries, EFB series and AGM series batteries for sails. The sail is very similar to the camel in technology, and the electrical performance is at the bottom level of the industry, especially the cycle performance will be greatly reduced with repeated charging and discharging, and the service life is slightly insufficient, and the shelf life is only 1 year. In terms of price, for example, the sail battery of the Buick model L2-400 costs 488 yuan, which is the same as the price of the camel, which is higher than the 458 yuan of Chaowei and slightly lower than the 490 yuan of Varta. Overall not cost-effective.
 
Sail has a wide range of offline sales channels, and most auto parts stores can provide sail batteries with lower prices, so you need to consider carefully when choosing.
