| Checking the „three-coloured“ indicator of the magic eye |
| Difference between the batteries with a magic eye, „three-coloured“ indicator. |
| l
| Batteries with the three-coloured indicator which are factory-installed are marked with a code which always begins with „1J0, 7N0 or 3B0“. Then the exact identification is for example 1J0 915 105 AC. |
| l
| The replacement batteries with the three-coloured indicator, which have been purchased from the Škoda Original Accessories, are marked with „000 915 105 Ax“, whereby „x“ is a variable. Then the exact identification is for example 000 915 105 AB. |

Note | t
| When recharging the battery via a charger or during operation, air locks can form under the magic eye, which can distort the indicator regarding the battery state. For this reason before an inspection of the battery, tap lightly and carefully on the magic eye (for example by using the handle of a screwdriver). The air bubbles disperse in this way and the colour indicator becomes more accurate. |
| t
| The fact that the magic eye is only located in one battery cell means that the reading is only relevant for that one cell. An exact assessment of the charge state of the battery is only possible by means of a battery load test → Chapter. |
| The colour indicator of the magic eye on these batteries gives information about the electrolyte level and the charge state of the battery. |
| The battery indicator can show three different colours: |
| t
| Green - Battery adequately charged and electrolyte level O.K. |
| t
| Black - Battery discharged or charged inadequately. Charge battery → Chapter. |
| t
| Colourless or bright yellow - Electrolyte level too low. Replace battery. |
