Check of a charge of the accumulator

If, despite the necessary level of acid, the accumulator does not give life signs, it is necessary to check a condition of its charging. Information on it can be received on the basis of the specific weight of acid in the accumulator. For carrying out this check you need the special areometer which you can hire at gas station.

 PERFORMANCE ORDER

  1. Unscrew an accumulator stopper.
  2. Suck away so much acid to provide free swimming of the areometer.
  3. Look what specific weight of acid is available: 1,28 kg/l – the accumulator is charged completely; 1,20 kg/l – it is loaded half; 1,12 kg/l – it was discharged.
