A car battery is an important element of electrical equipment along with the generator acts as a current source. The car battery serves several functions When combined with the generator battery delivers transients require high current and smoothes the ripple current in the electric network. In cars as starter used lead-acid batteries. The design of the batteries is constantly improving.

Each battery consists of six series-connected batteries combined in one housing. The casing is made of polypropylene resistant to acid and not conducting current. Separate battery combines alternating positive and negative electrodes is covered with a layer of active mass. The insulation plates of the opposite polarity provides a plastic separator.

The electrodes are made of lead alloy. In modern batteries the positive and negative electrodes are made of lead-calcium alloy. These batteries have low self discharge the loss of 50% capacity for 18 months and minimum water consumption 1 slack wax. This gives you the opportunity to completely eliminate the addition of water during use maintenance free battery.

Rare that you see a cheaper design so-called hybrid battery. It positive electrodes of lead-surmania and negative lead-calcium. In such batteries, the water flow in half to two times more calcium batteries but they also do not require maintenance. To increase the resistance of the electrodes to corrosion in a lead-calcium alloy can be added to the silver tin.

The electrodes have a lattice structure. Manufacturing technology of positive and negative electrodes are different. The grille of the negative electrodes according to the technology of Expanded metal is obtained by cutting through the lead sheet with the subsequent stretching. In the manufacture of positive electrodes using multiple technologies.

Advanced technology Power Frame. Each electrode Power Frame has a base frame and the inner veins of a certain direction which results in high rigidity and minimum linear expansion. More simple electrodes made by technology Power Pass vertical veins tightened the lug of the electrode Plate Chess veins of electrodes are staggered. Each electrode layer covers the active mass.

The positive electrode active mass consists of dioxide of lead. In the negative plate active mass is represented spongy lead. Electrodes placed in electrolyte which is a solution of sulfuric acid.
