Check of the battery

There are two possibilities of check of the battery. Depending on a way of check various measuring devices are necessary.

Check of density of electrolyte

 PERFORMANCE ORDER

  1. Check of density of electrolyte together with voltage measurement allows to draw an exact conclusion on extent of battery charging. For check the areometer which can cheap be bought in specialized trade is used. The more electrolyte density, the more emerges a float. On a scale it is possible to remove values of density in terms of the specific weight (g/ml) or degrees Baum (°va). The following values (have to be reached at a temperature of electrolyte of +20 °C).

Charging degree Petrol engine Diesel engine
+ ° Ve g/ml + ° Ve g/ml
it is discharged 8 1,06 11 1,08
it is half loaded 20 1,16 22 1,18
it is well loaded 30 1,26 32 1,28
  1. To check serially each can of the battery, electrolyte in all banks has to have identical density (the maximum difference of 0,04 g/ml. Otherwise it is possible to draw a conclusion on malfunction of the battery.

Check of the battery under loading

 PERFORMANCE ORDER

  1. To connect the voltmeter to battery poles.

If battery tension (without the connected consumers) is lower than 12 V, the battery is discharged and it needs to be loaded.

  1. To start the engine and to consider value of tension.
  2. At start tension of the charged battery should not fall lower than 8 V (at a temperature of electrolyte of +20 °C).
  3. If tension falls at once and in banks various density is revealed, it indicates malfunction of the battery.
  4. The general tension can be measured by a tester for batteries. To observe the instruction for application.

Values when checking

Capacity of Ach Test current And Current of loading And The minimum tension in 5-10 sec. at a temperature from 0 to +204 °C
54 265 200 9,4 B
64 380 300 9,0 B
88 395 300 9,5 B

If at this measurement (during 10 sec.) the general tension falls below the given value, the battery either is discharged, or is faulty.
