What are the characteristics of maintenance-free batteries

1. Due to the advantages of its own structure, the maintenance-free battery consumes very little electrolyte, so do not add distilled water during the service life. It also has the characteristics of shock resistance, high temperature resistance, small size, and small self-discharge. The service life is generally twice that of a normal battery. 2. Since the maintenance-free battery uses a lead-calcium alloy grid, the amount of water analysis that appears during charging is small, and the amount of water evaporation is low. In addition, the shell adopts a sealed structure, and the release of sulfuric acid gas is also very small, so it is comparable to other batteries. Compared with, it has the advantages of no need to add any liquid, less corrosion on the terminal posts and wires, strong resistance to overcharge, large starting current, and long power storage time. 3. The maintenance-free battery has only a small amount of gas in the electrolyte under the normal charging voltage, so there is no need to add distilled water during the entire period of use. Under normal conditions of the charging system, it does not need to be removed for supplementary charging. However, the specific gravity of the electrolyte should be checked during maintenance. 4. The maintenance-free battery does not escape acid mist during normal charging and discharging. The hydrogen and oxygen in the moisture analysis are also converted into water through the catalyst and pressure in the battery. When over-voltage charging, the internal air pressure exceeds the setting of the pressure relief valve. It is discharged to the outside only when the value is reached, so the electrolyte loss is less under normal use conditions. 5. The maintenance-free battery has a new type of safety synchronization device, which can not only keep acid gas inside the single cell battery, but also prevent sparks from entering the battery, which can not only reduce the battery explosion caused by external causes, but also keep the battery cover dry. Therefore, the corrosion of the terminal is reduced, and the electrical circuit connection is firm and reliable.
