Checking the „two-coloured“ indicator of the magic eye
Difference between the batteries with a magic eye, „two-coloured“ indicator.
l  Batteries with the two-coloured indicator which are factory-installed are marked with a code which always begins with „5K0“. Then the exact identification is for example 5K0 915 105 D.
l  The replacement batteries with the two-coloured indicator, which have been purchased from the Škoda Original Accessories, are marked with „000 915 105 Dx“, whereby „x“ is a variable. Then the exact identification is for example 000 915 105 DB.
Check the colour indicator of the magic eye
  Note
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.
The colour indicator of the magic eye no longer gives information about the charge state of the battery, yet only about the electrolyte level. An exact assessment of the charge state of the battery is only possible by means of a battery load test → Chapter.
The battery indicator can show two different colours:
t  Black - Electrolyte level O.K.
t  Colourless or bright yellow - Electrolyte level too low. Replace battery.
