15.1.1. Check of the storage battery

Electrolit level
The storage battery is filled by the sulfuric acid diluted with distilled water. As water can evaporate, from time to time it is necessary to check level of electrolit and if necessary to add the distilled water. Electrolit level should be between labels on the case of the storage battery. Storage batteries have usually protection against transfusion. For доливки it is necessary to turn away a stopper on a cover of each accumulator and to fill in the distilled water while it it not becomes visible. Storage batteries can have the pallet closed by a cover also.
Degree заряженности
(

Fig. 317. Check of density of electrolit: 1 — ареометр; 2 — a label of a test objective level of electrolit




To degree definition заряженности batteries on electrolit density it is applied ареометр. For the control it is necessary to turn away a stopper and to lower a tube ареометра inside банкирис. 317). By means of a rubber pear to type electrolit enough that the float in it could float freely. Depending on degree заряженности the electrolit density changes.
If the density is equal 1,28 g/sm3 the storage battery is completely charged; at 1,12 g/sm3 the storage battery is completely discharged. Intermediate values specify in degree заряженности. To check up degree заряженности in all accumulators.
Gymnastics of the storage battery
In strongly discharged storage battery the distilled water should be added only after gymnastics. During gymnastics electrolit level raises, therefore the storage battery filled according to the instruction can "begin to boil". The gymnastics current at first should not exceed 10 % of capacity of the storage battery, for example, at capacity of the accumulator 45 Ач it should make 4,5 j the pressure equal approximately 2,4–2,45 In on each accumulator is reached, the gymnastics current should be reduced half. Depending on a design зарядного devices the gymnastics current in most cases will automatically decrease. The storage battery is considered completely charged if the electrolit density in the next two hours does not change.
Stoppers of accumulators, as a rule, should turn away and remain on apertures in not tightened condition. Thereby possibility of an exit of the detonating gas consisting of oxygen and hydrogen is provided. As at intensive gymnastics inevitably occurs разбрызгивание electrolits the surfaces adjoining to the storage battery, it is necessary to protect. At gymnastics indoors it is necessary to provide good ventilation. Not to use at all open fire for illumination of apertures in the storage battery.
At application зарядного devices can be left the storage battery in the car. With a view of safety it is necessary to disconnect both wires from plugs of the storage battery.

The prevention
At a detachment of a wire from the storage battery the information from memory of electronic memories is erased.

Removal and installation

Fig. 318. A way of fastening of the storage battery: 1 — a tightening lath of a flange of the storage battery; 2 — a clamping plate; 3 — a bolt, 20 Нм; 4 — the holder




The storage battery is in a motor compartment and is fixed by a clamping plate 2 (fig. 318) and a tightening lath 1. Before removal it is necessary to disconnect wires from the storage battery. Always at first it is necessary to disconnect a negative wire. Then to turn away a bolt 3, to remove a clamping plate 2 and to take out the storage battery.
At installation of the storage battery at first it is necessary to smooth out plugs, to get the storage battery with effort a flange on one party under a tightening lath 1. To establish a clamping plate 2 and densely to press it to the storage battery, to insert a bolt and to tighten its moment 20 Нм.
For installation on the car storage batteries in height of 175 mm or 190 mm approach.
Start-up of the engine with the discharged storage battery
The most simple way of start-up is start-up with use of a special wire for connection to the storage battery of other car. The wire should possess the considerable area of cross-section section and large connecting clips to pass a current from one storage battery to another. At first it is necessary to connect плюсовый a wire, then "minus". The assistant should start up the engine and support average frequency of rotation that the generator could develop an additional current.
The most known way of start-up of the engine with strongly discharged battery — car towage.
