  Battery answer:

   1. There are many factors that affect the battery life, not only in the design and manufacture of the battery, but also in the user's use and maintenance conditions. For the former, the corrosion resistance of the positive electrode grid and the water loss rate of the battery are the two most important factors affecting the battery life. Due to the increase in the thickness of the positive electrode grid, the use of Pb-Ca-Sn-Al quaternary alloy The battery life of the battery can reach 10×15 years, but from the results of battery use, the loss rate has become the most critical factor affecting the service life of the sealed battery.

   For AGM sealed lead batteries, due to the thin liquid design, the battery capacity is very sensitive to the amount of electrolyte. The battery loses 10% of water, its capacity is reduced by 20%, and its water loss is 25%. The battery life ends. The gel-sealed lead battery uses a rich liquid design, and the electrolyte density is lower than that of the AGM sealed lead battery, which reduces the corrosion rate of the grid alloy. The electrolyte volume is 15% less than the latter, and the sensitivity to water loss is low. These measures help to extend the service life of the battery.

   According to the information provided by the battery company, the gel electrolyte contains enough water to run the battery for 12 to 14 years. In the first year of battery operation, water consumption is less than 5%, and then decreases year by year. Four years later, the total water consumption was only 2%. OP2V sealed battery after 10 years of floating charging operation, under the condition of 2.27V/cell, the battery capacity is still 90%. According to some domestic postal and telecommunications departments, although the price of colloidal sealed lead batteries is high, their service life is longer than that of domestic AGM sealed lead batteries.
