Low Maintenance Batteries, Checking

Low maintenance batteries with charge indicator (magic eye) and foil sealed cell caps, checking

Identification







- Battery cell caps -2- covered with plastic foil.
- Charge indicator -1- 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. Component Tests and General Diagnostics
- 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.


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. Electrolyte Level, Checking (Batteries With Charge Indicator)

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 specified in this manual.
- Intermittent contact at battery terminals may spark or cause electrical system malfunctions.
