For special vehicles, the battery is an important electrical device and one of the main power sources for special vehicles. With the rapid development of special-purpose vehicles, maintenance-free batteries have been used in a large area. What advantages does this maintenance-free battery have with previous batteries? Let‘s compare the differences between them:
1, Different life spans
Maintenance-free batteries Due to their structural advantages, the consumption of electrolyte is very small, and it is basically unnecessary to replenish 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, Different materials
Traditional batteries are made of lead-bismuth alloy, and maintenance-free batteries are made of lead-calcium alloy. The former uses bismuth and the latter uses calcium, which is the fundamental difference between the two.
3, The phenomenon is different
Different materials will produce different phenomena: the traditional battery will reduce the liquid during use, because the flaw on the grid will contaminate the sponge-like pure lead on the negative plate, which will reduce the reverse of the battery after full charge. Electromotive force causes excessive decomposition of water.
A large amount of oxygen and hydrogen escape from the positive and negative plates, respectively, reducing the electrolyte. By replacing the strontium with calcium, it is possible to change the back electromotive force of the fully charged battery, reduce the overcharge current, and reduce the liquid vaporization speed, thereby reducing the electrolyte loss.
4, Different functions
Compared with the traditional battery, the maintenance-free battery does not need to add any liquid, has less corrosion to the wiring pile head and wires, strong anti-overcharge capability, large starting current, and long storage time.
The above is the difference between the maintenance-free battery on the special vehicle and the ordinary battery. According to the above comparison, the maintenance-free battery is actually more practical than the battery in all respects, but the maintenance-free battery is not as maintenance-free as it is literally. On the contrary, it also needs maintenance and Maintenance, in order to extend its service life.
