General Information
The "Magic Eye" indicator provides information concerning the battery electrolyte level and charge state.
To obtain an accurate reading, gently tap the indicator with a screwdriver handle or rock vehicle slightly. This disperses the air bubbles that occur normally during battery charging (even during vehicle operation) that adversely affect indicator reading. Thereby, the color indication of the magic eye is more accurate.
NOTE:
- Especially when a battery is charged, including when the battery is charged while driving, air bubbles can form under the magic eye. These bubbles may cause color indication of the magic eye to read inaccurately. Prior to reading display, rock vehicle slightly or lightly tap on battery housing to disperse any air bubbles.
- As the magic eye indicator is located in a single cell, the indication is only valid for that cell. The magic eye indicator reading by itself must never be used to assess battery condition. Always confirm battery condition by testing with Midtronics MCR 340 → Battery, Testing with Midtronics MCR340V .
- The magic eye can be installed at various locations on battery.
There are three possible color indications:
- Green : Battery is sufficiently charged.
- Black : Insufficiently charged 65 % or discharged. Charge battery → Battery, Charging
- Colorless or light yellow : Replace battery. Heed "WARNING" below.
CAUTION:
- Due to risk of explosion, batteries with colorless or light yellow "Magic Eye" indicator must NOT be tested, charged or be jump-started!
- Always replace battery.
