Accumulator charging check

  2. To turn out a stopper of the rechargeable battery.
  3. To absorb the areometer it is so much electrolyte that the areometer (spindle) freely floated in it.
  4. 1,28 kg/l – the accumulator is completely charged; 1,20 kg/l – it is loaded on a half; 1,12 kg/l – it is discharged.
