Battery with charge indicator (magic eye), checking
Charge indicator -arrow- displays electrolyte level and charge condition.
NOTE:
- As the charge indicator is located in a single cell, the indication is only valid for that cell. An exact assessment of battery condition should always be confirmed by performing a load test
- If the charge indicator on batteries in excess of 5 years old are colorless, DO NOT attempt to top and/or recharge battery. Battery must be replaced.
- Air bubbles that occur normally during battery charging (even during vehicle operation) may adversely affect charge indicator reading. To obtain an accurate reading, gently tap the charge indicator with a screwdriver handle or rock the vehicle in order to displace any possible air bubbles that have formed.
- Where equipped, battery cell caps may be covered with plastic foil
Charge indicator readings
- Green = sufficient charge (and electrolyte level) OK
- Black = no charge or insufficient charge. Refer to Battery, charging .
- Colorless or yellow = critically low electrolyte level. Top up with distilled water immediately. Refer to Electrolyte level - battery with cell caps, checking .
