Automotive battery mainly by the plate, clapboard, electrolyte, shell and other components.

Armour plate and Plate group

The plate is the main component of the electric energy storage battery. It is made into a grid frame (grid) form, attached to the top of the active material, JIS Standard Dry Charged Car Battery or Car Batteries the plate is divided into two types. The active material attached to the plate is lead dioxide and is brownish red, and the attached active material on the plate is a sponge-like pure lead, which is dark gray, and is a negative plate. The charging and discharging of the automobile battery is realized by the chemical reaction of the active substance on the positive and negative plate and the sulfuric acid solution. Put the proper number of positive, JIS Standard Dry Charged Car Battery or Car Batteries negative plate by a positive and negative arrangement into a plate group, at the same time, in each positive plate inserted in the middle of a clapboard, the plate group to become a table battery, because the positive plate on the active material is looser, mechanical strength is low, if the plate on both sides of the discharge uneven, will form the positive plate arch and make its active material off, so, in each single lattice, JIS Standard Dry Charged Car Battery or Car Batteries the negative plate than the positive plate more than one, so that you can ensure that after the fit, each positive plate is in the two negative plates, The two sides discharge evenly and reduce the arch and active material of the plate.


The function of the clapboard is to separate the positive and negative plates to prevent short circuit of the plate. Clapboard is commonly used for plastic, hard rubber, JIS Standard Dry Charged Car Battery or Car Batteries such as separators made of a groove, a smooth side. When the person is loaded, the groove surface should be perpendicular to the positive plate. In this way, the cathode plate in the chemical reaction, get more electrolyte and respond to the full. In addition, the bubble can rise with the tank when the car battery is charged, JIS Standard Dry Charged Car Battery or Car Batteries and the active material that falls off will sink along the trough.


Electrolyte is the main substance of chemical reaction inside the automobile battery. The electrolyte of automobile battery is made of pure sulfuric acid and distilled water according to a certain proportion. The sulfuric acid density is high, which can enhance the chemical reaction and improve the electromotive force. In winter, JIS Standard Dry Charged Car Battery or Car Batteries it can avoid the solution of electrolyte freezing. But the density is too high, will make the plate corrosion action to accelerate, shorten the plate and the shelf life, the electrolyte density is generally 1.24-1.28G/CM3 (c) in areas or seasons with high temperatures, low densities should be used, and high densities should be used in areas or seasons with lower temperatures.

Enclosure (Container)

The shell is made of hard rubber or plastic, the inside is separated into a few single cell batteries, the bottom of the shell is raised with a wire rod (convex ribs) used to place the plate group, adding the lid on the liquid mouth, the cover has vent holes, JIS Standard Dry Charged Car Battery or Car Batteries they should be kept unblocked to prevent the casing inside the increase in gas and the shell expansion crack. The positive and negative columns of each table battery plate group are connected in series by a joint, that is, the cathode column of a single cell battery and the negative column of the adjacent table battery.
