Battery — design description

Six cells connected in series form the heart of a 12-volt car battery. Each cell is a combination of positive and negative plates, generating a voltage of about 2 volts through a kind of cooperative chemical action. The plates are made of gratings of solid lead, which are filled with active mass. A positively charged plate contains lead dioxide, a negatively charged plate contains pure lead. Between them is a separator. It separates the plates from each other, but the electrolyte can pass through microscopic pores. The electrolyte is an electrically conductive liquid that is approximately 37% concentrated sulfuric acid and 63% distilled water.

The battery stores electricity

Inside the battery, chemical processes take place to absorb energy and store it. When current is supplied, chemical energy is converted into electrical energy. The most important task of the battery is to supply the starter with the necessary power when starting the engine: depending on the engine and the type of starter, up to 2000 watts of power is generated for a short time - for this, the battery must always be in the best shape. When starting a cold engine, most of the enormous power goes to internal losses due to friction. When starting a warm engine, the starter requires about one-fifth of the power. Between all oscillating and rotating nodes, the engines are more «places», A «hot» oils also become more fluid than cold lubricants, which are slowly mixed in the lubrication system.
