| Checking battery with magic eye |
Caution | Danger of injury! Observe warning notices and safety regulations → Chapter! |
|
| The magic eye provides information concerning the level of the electrolyte and the charge state of the battery. |
| Batteries with a magic eye are produced in two versions: |
Note! | Because the magic eye is located in only one cell, the display applies only to this cell. An exact determination of battery's condition is only possible through a load test → Chapter. |
| –
| Before carrying out a visual check, tap the magic eye lightly and carefully using the handle of a screwdriver. |
| The air bubbles, which can influence the display, will dissipate when doing this. The colour display of the magic eye will therefore be more accurate. |
Note! | t
| Air bubbles can form below the magic eye particularly when the battery is being charged, including during normal vehicle operation. These falsify the colour display of the magic eye. |
| t
| The magic eye can be located at various positions on the battery. |
| Three different colour displays are possible: |
| t
| “Green”, battery is charged sufficiently. |
| t
| “Black”, battery partly discharged, charge state < 65% or completely discharged. |
| t
| “Colourless or yellow”, battery must be renewed. |
