The difference between maintenance-free batteries and traditional batteries

by:Power Kingdom     2021-04-25
The phenomenon of liquid loss occurs in traditional batteries during use. This is because the antimony on the grid will contaminate the lead on the negative plate, causing excessive decomposition of water, and a large amount of oxygen and hydrogen will overflow from the positive and negative plates, causing the electrolyte cut back. The maintenance-free battery is made of lead-calcium alloy. Because the battery uses the lead-calcium alloy as the grid, the amount of water decomposition generated during charging is low, and the amount of water evaporation is also low. In addition, the shell is sealed and the sulfuric acid gas is released. Compared with traditional batteries, it has the advantages of no need to add any liquid, less corrosion to terminal posts, wires and body, strong resistance to overcharge, large starting current, and long power storage time. In recent years It is very popular in China.   The storage capacity of the battery can be reflected on the dashboard. When the ammeter pointer shows that the battery is insufficient, charge it in time. Sometimes it is found that the battery is not enough on the road, and the engine can’t start when it stops. As a temporary measure, you can ask other vehicles for help. Use the batteries on other vehicles to start the vehicle, and connect the negative and negative poles of the two batteries, and the positive and positive poles. .   If the battery is not used for a long time, it will slowly discharge by itself until it is scrapped. Therefore, the car should be started every once in a while to charge the battery. Another way is to unplug the two electrodes on the battery. What should be paid attention to is to unplug the positive and negative electrode wires from the electrode column. First, unplug the negative wire, or remove the connection between the negative electrode and the car chassis, and then Then unplug the other end with the positive sign (ten).   The storage battery has a certain service life and needs to be replaced after a certain period of time. When replacing, follow the same order as above, but when connecting the electrode wires, the order is exactly the opposite. Connect the positive electrode first, then the negative electrode.
