| Battery with magic eye: verification |
| The eye may be used to gain information about the level of electrolyte and the charge in the battery. |
Note! | As the eye is only fitted to one of the elements, the indication is only valid for that element. An exact evaluation of the state of the battery can only be obtained by checking the idle voltage of the battery → Chapter. |
| –
| Before visually checking the acid level, tap the magic eye carefully and gently with the handle of a screwdriver. |
| The bubbles that may influence the reading should be dissolved In this way the colour indicator of the eye will measure precisely. |
Note! | t
| Above all it must be realised that while the battery is being recharged, including when the vehicle is running, air bubbles may be formed underneath the eye. These bubbles change the colour of the magic eye sender. |
| t
| If a battery is more than 5 years old and the magic eye is colourless or yellow, the battery needs replacing. |
| t
| The magic eye may be in different parts of the battery. |
| t
| Three colours may be distinguished: |
| –
| Green → battery well charged. |
| –
| Black → battery discharged or charge insufficient. Charging the battery → Chapter. |
| –
| Clear or yellow → the electrolyte is at a critical level, and distilled water must be added → Chapter. |
| –
| Finally a verification of the electrolyte density of the battery must be carried out → Chapter. |
