THE PROBLEM
Battery failure becomes expensive fast in demanding environments
In heavy equipment and off-road operations, even a small battery issue can cause major disruption. Delayed starts, field breakdowns, emergency service calls, and lost equipment availability all add cost.
These environments are hard on batteries, and battery problems are easy to overlook until the equipment fails when it is needed most.
THE CADEX SOLUTION
Battery decisions built around uptime
Cadex helps teams test battery condition more efficiently so they can identify weak batteries earlier and make better service decisions.
Instead of replacing batteries on age alone or waiting for failure, maintenance teams can use battery condition data to plan service at the right time.
That supports better uptime, better maintenance scheduling, and better use of batteries that still have reliable life left.
HOW IT WORKS
Fast testing for batteries in the field and shop
Cadex testing gives service teams a faster way to assess battery condition and spot batteries that are approaching failure. That allows maintenance staff to address battery risk during planned service instead of after the equipment stops working.
For operations that depend on availability, that is a major advantage.
WHY THIS MATTERS
Built for maintenance teams that cannot afford avoidable downtime
The value is clear: predict battery risk earlier, reduce field failures, and keep equipment available when it matters most.

Validating performance by EIS Test
Battery Check in Seconds
The battery is the weakest link in a chain that causes half of all system failures. Battery diagnostics has been lagging, but technology is available that observes capacity fade to fully use each battery with call to replace before failure.
The Spectro CM-24 tests battery health by modeling a battery against a matrix to secure Minimum Operational Reserve Energy (MORE) based on capacity, the leading health indicator.
Threshold Setting
Capacity pass/fail levels for deep-cycle batteries are commonly set to 60%. A PASS assures full day service; FAIL calls for replacement or lower tasks.
The Spectro CM-24 comes with a matrix of choice and ability to download other matrices from the Matrix Library. The matrices are kept in the CadexCloud, a web app that also stores test results and shares data with fleet supervisors.
How does Spectro™ work?
A frequency scan produces a Nyquist plot that models a battery against a matrix to extract capacity, state-of-charge (SoC) and other characteristics. The test is non-invasive and accuracy rests on the Matrix Integrity Level (MIL) that can be improved by scanning additional batteries of same-model but with diverse performances to capture all anomalies.
The EIS Direct-Drive tests batteries in 30 seconds with capacities of up to 300Ah. The battery is not agitated during testing and the compact test unit stays cool. Scientists predict that battery diagnostics will advance to Multi-Model EIS methods, a patented technology Spectro™ devices use.
Checking Battery Match
Battery runtime is governed by the weakest link in a chain. Matching can be assured by measuring leftover charge of each pack after service with the Spectro CM-24. State-of-charge of a well-matched string should be within 10%. Replace low performers with a pack of similar capacity.
Operation
Settings are entered through the host with tests results shown in numbers and by graphics. The system works in local mode by storing test data in the host with optional connection to CadexCloud to share test results with fleet supervisors.
Saved data includes battery status, charge levels, internal battery resistance and temperature, as well as VIN records and work orders. Compatible printers produce print reports and labels.
Historic Test Data
Testing is simplified by marking each battery with QR code. A scan connects the host to CadexCloud to download custom matrices, view previous results and store new readings.
With matrices available from the Matrix library, Spectro devices form an open test platform to service all major batteries.
Capacity Thresholds
Pass/fail settings can be changed by selecting matrices with different MORE thresholds. This enables reserving top performers for critical uses while keeping regular packs for everyday uses.
