The storage battery
The storage battery is the centre of onboard electrosystem Audi 80. Various consumers of a food use a stock of its energy, and the storage battery from the generator is charged.
The electrode (lead plate) contacts to the dissolved sulfuric acid (electrolit) and gives under the influence of a solution positive ions, that is электрически charged частцы, to electrolit. Thereby between electrolit and a lead plate electric pressure is created.
However the pressure created as a result of "voluntary" transition of charged particles, not enough, and on the accumulator submit зарядное pressure. As a result of it sulphate of lead of the discharged accumulator room of the battery turns on a positive electrode in диоксид lead, and on negative – to spongy lead. Simultaneously in electrolit sulfuric acid, an external sign of almost complete process of gymnastics – occurrence of vials of gas is again formed.
At an accumulator discharge there is a return process. Диоксид lead of a positive plate and spongy lead negative again turn to lead sulphate, and sulfuric acid is spent, and water is formed. Therefore with a discharge of the storage battery the acid density decreases.
Designation of the storage battery
In models Audi 80 with 4 and 5-cylinder engines the storage battery is located behind on the right in a motor compartment. In models with the 6-cylinder engine: the accumulator is located at the left ahead in a motor compartment. On installation sites it is protected by a cover.
Parametres of the storage battery
Pressure and capacity: in a designation 12 В/40 Aч the first (12), of course, specifies pressure. Behind inclined line the current strength which the accumulator is capable to give for a time unit is resulted – Aч means ampere-hours. It is the nominal capacity of the battery measured according to standard conditions. In practice it is necessary to count only on 2/3 specified ampere-hours; at older accumulator only on half.
