Battery With Charge Indicator (Magic Eye), Checking

Batteries With Charge Indicator (Magic Eye), Checking

Identification
- Battery housings are either black or white.







- Charge indicator -arrow- displays electrolyte level and charge condition.

Charge indicator, readings
- Green -> sufficient charge (and electrolyte level) OK
- Black -> no charge or insufficient charge
- Colorless or yellow -> critically low electrolyte level. Top up with distilled water immediately

NOTE:
- 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.
- For technical reasons, some batteries are equipped with sealing plugs covered with plastic foil.

Visual check
Always carry perform a visual check of the battery before checking no load voltage, electrolyte specific gravity and load test.

Check for:
- Cracked battery case and resulting corrosion damage to surrounding area.
- Loose, damaged or corroded battery posts and terminals.


WARNING!
- Ensure that all battery post/terminal connections are securely installed and tightened according to the torque value.
- Intermittent contact at battery terminals may spark or cause electrical system malfunctions.
