A, commonly used the classification and features of the storage battery

by:VELA     2020-03-14
At present, the commonly used motorcycle battery mainly divided into three categories, respectively for common battery, dry lotus battery and maintenance-free battery 3 kinds. 1) Ordinary storage battery; Common battery plate is made up of lead and lead oxide, the electrolyte is sulfuric acid aqueous solution. It is the main advantage of voltage stability, the price is cheap; Defect is lower than can ( The battery storage of electricity per kg) , short service life and maintenance frequency. 2) Dry lotus battery: it is the full name of dry charged lead-acid battery, it is the main characteristic of negative plate has higher storage capacity, under completely dry condition, can save the electricity generated by in two years, when using, need to join the electrolyte, such as 20 - 30 minutes to use. 3) Maintenance-free storage battery, maintenance free batteries due to its structural advantages, the consumption of the electrolyte is very small, in the service life of the basic don't need to add distilled water. It also has a shock resistant, high temperature resistant, small volume, the characteristics of uniformity. General twice of the normal battery service life. The free maintenance battery on the market has two kinds: the first in one-time add electrolyte later use when buying does not need maintenance ( Add supplementary liquid) ; Battery itself is another good factory had already added electrolyte and block, users won't add supplementary fluid. Second, the structure of the battery, the general battery lead-acid battery is made up of positive and negative plate, plate, shell, electrolyte and wiring and other components of the pile head, the discharge of chemical reactions is depend on the positive plate active substances ( Lead dioxide and lead) And the negative plate active substances ( Spongy pure lead) In the electrolyte ( Dilute sulphuric acid solution) Under the role of, of which the plate grid frame, traditional battery lead antimony alloy, maintenance-free battery is made of lead calcium alloy, the former with antimony, the latter with calcium, which is fundamental to both the mark. Different material can produce different phenomena: traditional battery will happen in the process of using liquid reducing phenomenon, this is because the gate frame of antimony can lead pollution on the negative plate spongiform pure, weakened after fully charged battery in the counter electromotive force, caused by excessive water decomposition, a large number of oxygen and hydrogen escape from the positive and negative plates respectively, reduce the electrolyte. Use calcium instead of antimony, can change the counter electromotive force after fully charged battery, reduce charging flow, liquid vaporization rate reduce, thereby reducing the loss of the electrolyte. Due to the free maintenance battery USES lead calcium alloy grid frame, charging when the water quantity is little, low moisture evaporation, coupled with the outer seal structure, the acid gases released is very few, so it is compared with the traditional battery, do not need to add any liquid, pile head for wiring, wire less corrosion, overcharge resistance is strong, large starting current, power advantages of long storage time. Maintenance-free battery because of its under normal charging voltage, electrolyte to produce only small amounts of gases, plate has a strong ability to resist charging, and has a small internal resistance, cold starting performance is good, than conventional battery service life is long, etc, and therefore does not need to add distilled water, throughout the duration in the charging system under normal circumstances, do not need to supplement charge from removed. But at the time of maintenance to the proportion of the electrolyte. Most of the free maintenance battery has a hole in the lid shape liquid ( Temperature compensation type) Hydrometer, it will change its color according to the variation of the proportion of the electrolyte. Can indicate the battery state of store electricity and the height of the electrolyte level. When hydrometer indicator green eye, which indicates that charging is enough, storage battery normal; When instructed eye little green dots or black, highlights the need for charging battery; When indicates the eye light yellow, indicates a battery internal fault, needs to be repaired or replaced. Maintenance-free battery charged can also supplement, charging ways and common battery charging method is essentially the same. 3 - 4 v. Pay attention to using conventional charging method consumes more water, charging current when charging should be slightly smaller ( 5 a) 。 Cannot be quick charge, otherwise, the battery may explode, causing cuts. When maintenance free storage battery hydrometer, shown as a light yellow or red, show that the battery is close to scrap, even if the recharging, service life long. At this time of charging only for emergency expedient. Conditional, available with the free maintenance battery current - Charge the battery by voltage characteristic of charging equipment. The device can ensure adequate electricity, and can avoid overcharge and consume more water.
