The general battery / lead-acid battery is composed of a positive and negative plate, a partition, a housing, an electrolyte, and a wiring pile head, and the chemical reaction thereof is based on a positive electrode plate active material (lead and lead) and a negative plate activity. Substance (sponge pure lead) is carried out under the action of the electrolyte (dilute sulfuric acid solution), wherein the plate of the plate, the lead-ribbon-free alloy of the conventional battery, the maintenance battery is made of lead calcium alloy, and the former uses antimony, With calcium, this is the fundamental difference point of both. Different materials will produce different phenomena: the traditional battery will have a reduction in the use process because the bismuth on the grid will pollute the sponge-shaped pure lead on the negative electrode plate, and weaken the anti-storage battery. Electric potential, resulting in excessive decomposition of water, a large amount of oxygen and hydrogen from escape from the positive and negative plates, and reduces the electrolyte. With calcium, it can change the back electromotive force of the fully charged battery, reducing the overcharge stream, the liquid gasification speed is reduced, thereby reducing the loss of the electrolyte.
Since the maintenance-free battery is used to use a lead calcium alloy grid, the water produced during charging is small, the amount of water evaporation is low, and the shell is used to use a sealing structure, and the released sulfuric acid is very small, so it compared to the traditional battery, It has the advantages of less of the need to add any liquid, small to the wiring pile, the wire corrosion, strong anti-charging capacity, large start current, and long battery storage time.
The maintenance-free battery is due to its normal charging voltage, the electrolyte only produces only a small amount of gas, and the plate has strong anti-charging capability, and has a small internal resistance, the low temperature starting performance is good, and the long-term service life is characterized. Thus no addition of distilled water during the entire use, under normal conditions of the charging system, no additional charging is required. However, the proportion of its electrolyte should be checked at maintenance.
12V-free maintenance battery
Most maintenance-free batteries have a pore liquid (temperature compensation type) specific gravity on the cover, which varies according to the change in the specific gravity of the electrolyte. It can indicate the storage state of the battery and the height of the electrolyte level. When the indication of the specific gravity is green, it indicates that the charging is enough, the battery is normal; when the eye is very small or black, it indicates that the battery needs to be charged; indicating that the eye shows light yellow, indicating that the internal failure of the battery is faulty, need repair or Replace it.
When there is condition, the maintenance-free battery can be charged with a charging device with current-voltage characteristics. The device guarantees sufficient electricity and avoids more water to consume more water.
Generally, this type of maintenance-free battery can be stored from the factory to use for 10 months. The voltage and capacitance remain unchanged, and the mass difference is lowered by voltage and capacitance after the factory. At the time of purchase, there is 3 months, which can check whether the voltage and capacitance of the battery will meet the requirements of the specification. If the voltage and capacitance have a decline, it means that the material inside is not good, then the battery is Quality is definitely no, it is possible to make a water battery through the dealer to charge.
