THE PROBLEM
Why battery failures still surprise fleets
A starter battery can seem fine during a basic inspection and still fail soon after. Common checks do not always show how much useful energy the battery really has left.
For fleet operators, that creates a costly cycle: roadside service calls, no-start events, delayed vehicles, technician time, and batteries replaced too early just to be safe.
Cadex helps teams make battery decisions based on condition instead of guesswork.
THE CADEX SOLUTION
A smarter way to test battery health
Cadex Spectro™ focuses on battery capacity, a more useful indicator of battery health than a simple pass-fail check. In a fast test, technicians can identify batteries that are still serviceable, batteries that should be watched closely, and batteries that should be replaced before failure.
That means fewer surprises, better maintenance timing, and more confidence in every service decision.
HOW IT WORKS
Fast battery testing designed for real service environments
Spectro™ compares a battery’s electrical behavior to known battery models to estimate condition and remaining usefulness. This gives technicians a practical health reading without the long process of traditional testing.
Instead of waiting for the battery to fail in service, teams can identify risk earlier and act during scheduled maintenance.
WHY CAPACITY MATTERS
Why capacity tells a better story than CCA alone
A battery may still crank an engine even when its reserve energy has already dropped too far. That is why cold cranking numbers do not always tell the whole story.
Multi-mode EIS in Spectro™ departs from load testing by assessing the electrochemical evidence of a battery with a frequency scan. Rather than checking overall battery health, Spectro™ assures Minimum Operational Reserve Energy (MORE) in capacity and reads internal resistance (Ri) in a non-invasive 30-second test. Capacity and Ri do not correlate.
For the customer, the message is simple: a battery that starts today may not last until the next service interval. Capacity testing helps you catch that earlier.
