13.5. Check of the storage battery

If, despite the necessary level of electrolit in the accumulator, it makes "languid" impression, by means of the special device check up degree разряженности. Упрощенно this device is the glass cylinder in which special amendments (ареометр) measures level of density of electrolit. For this purpose ареометр checks электролитическую concentration of the soaked up liquid of the accumulator. Certainly, it is possible to measure also level разряженности by means of a multimeter (accuracy отсчитывания 0,02 Volt): on the basis of the measured value of the established pressure it is possible to define level разряженности the storage battery.

Measurement of density of electrolit


  1. Before measurement carrying out leave the accumulator at least at six o'clock in rest.
  2. Remove then запорную an accumulator stopper.
  3. Hold the measuring device in a liquid vertically and soak up in it so much electrolit that ареометр freely floated in the cylinder.

    Values of measurements

    Weight acids (kg/l)
    Accumulator condition
    It is completely charged
    It is charged half
    It is discharged

    Measurement of density of electrolit: it is possible in accumulators only with served sections. The density is measured in each separate section. For this purpose hold денциметр 1 vertically and soak up so much electrolit that a float (the aerometre 2) freely floated. In "the healthy" battery of section have about identical values. Carry out their comparison on a scale 3 in the top part of aerometre.

Pressure measurement


  1. If last process of gymnastics passed less than six hours back approximately for 30 seconds include a passing light: it will allow to level possible peaks of pressure.
  2. After the next 4–5 minutes of expectation check up pressure of the accumulator. Thus switch off in the beginning all consumers of a current.

    Values of measurements

    Pressure ()
    12,26 and more
    Accumulator condition
    100 % it is charged
    75 % it is charged
    50 % it is charged

    By means of a multimeter it is carried out quickly: measurement of pressure of the accumulator. At pressure more low 12,3 Volt it is necessary to spend accumulator gymnastics immediately.
