What are the characteristics of maintenance-free batteries?

The characteristics of maintenance-free batteries The biggest difference between maintenance-free batteries and ordinary batteries is the difference in plate material. Not only improves the performance, but also extends the service life and storage life. (1) The maintenance-free battery loses less water, and generally does not need to add distilled water during use. (2) The grid frame of the maintenance-free battery is made of lead-calcium alloy, which is characterized by fine crystal grains, corrosion resistance, not easy to form a micro-battery, and small self-discharge. (3) The maintenance-free battery has a gas collection chamber and a new type of ventilation device, which can prevent water loss and effectively prevent acid gas from escaping, thereby greatly reducing the corrosion of sulfuric acid gas to the pole pile connector. (4) The starting current of the maintenance-free battery is larger than that of the ordinary battery, and the starting performance is better. On the one hand, the electrical conductivity of lead-calcium alloy is better than that of lead-antimony alloy, the internal resistance of the battery is small, and the output current is large; on the other hand, it is maintenance-free. The battery adopts internal connection, which shortens the connection length, has low power loss and high discharge voltage. (5) The maintenance-free battery adopts the lead-calcium alloy to make the grid, which increases the mechanical strength, improves the charging resistance, and effectively prevents the active material from falling off and improves the service life.
