|
| General information about colour indicator: |
| The general introduction of the “2-colour” indicator took
place gradually in 2009. The “2-colour” indicator does not
include »green« to indicate the
charge state. |
| The colour indicator provides you with information on the
electrolyte level of the battery. |
| The battery's charge state can no longer be read off via the
colour indicator. The battery test has to be used for this
purpose,

| 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
| Air bubbles can form under the sight glass, particularly
when a battery has been recharged, i.e. also when the battery
has been charged during normal vehicle operation. These falsify
the reading of the colour indicator. |
| Since the colour indicator is only located in one battery
cell, the indicator also only applies to this battery cell.
Determining the exact condition of the battery is only possible
by means of a battery test
→ Chapter. |
| The colour indicator can be located at various positions on
the battery. |
| Three different colour displays are possible: |
| »Black«, electrolyte level is
OK. |
| »Light yellow«, electrolyte
level too low. The battery must be renewed. |
WARNING
| It is not permissible to test or charge batteries
whose colour indicator is light yellow. Do not
slave/jump start the vehicle! |
| Danger of explosion when checking and charging or
slave/jump starting. |
| These batteries must be renewed. |
