- If the accumulator seems "powerless" despite correct level of electrolit, it is necessary to check up degree разряженности. For this purpose it is necessary to find out relative density of storage acid. For the control for you it is necessary ареометр.
- To turn out a stopper of the storage battery.
- To absorb ареометром it is so much electrolit that ареометр (spindle) freely floated in it.
- 1,28 kg/l – the accumulator is completely charged; 1,20 kg/l – it is charged on half; 1,12 kg/l – it is discharged.
