    Default Motorcraft battery eye indicator colour

    Can anyone tell me the correct answer as there seems to be conflicting websites which say a healthy battery should be showing what colour.

    Ideally if anyone has a brand new motorcraft battery fitted, please tell me the colour in the eye. Is it red or green.

    Normally green would indicate a good battery-but remember the 'magic eye' is only indicating the condition of one cell.

    Yes-but have your battery checked with a tester to confirm the condition-most garages etc will do a battery check for free...........

    Better late than never!!! The Magic EyeŽ that is used in Motorcraft batteries provides 4 stages of indication, they are:
    1. Green: battery is charged and the acid level is good.
    2. Yellow: Battery is partially dis-charged and the acid level is good. Re-charge the battery or drive the vehicle.
    3. Red: Battery is dis-charged and the acid level is good. Charge the battery.
    4. Clear and bright: Acid level is low!!! Add distilled water if possible. If not, change out the battery. Do not charge or jump start the battery!!!

    While the Magic EyeŽ is only located in one cell, it is still quite accurate for indicating the state of charge of all cells as they are within 95% of the same condition. If there is a catastrophic failure such as an internal short circuit, the battery would be bad, but the eye would still show green as the density of the acid is still technically correct. This is very rare.
