THE PROBLEM
Marine battery failure is harder to solve once underway
Marine vessels depend on batteries for starting, navigation, communications, lighting, and onboard systems. When a battery fades, the cost of discovering the problem late can be much higher than finding it during planned service.
THE CADEX SOLUTION
Assess battery capacity before the vessel leaves the dock
Spectro CM-24 validates battery health by modeling the battery against a matrix to assess capacity, CCA, and state-of-charge. The marine source notes that custom matrices can support large vehicles, machinery, and marine vessels, including lead-acid and lithium-based chemistries.
HOW IT WORKS
Fast testing with cloud-ready records
The non-invasive test takes about 30 seconds and can be connected to a host by Bluetooth. Results can be stored locally or shared with CadexCloud, including status, charge level, resistance, temperature, VIN or asset records, and work orders. QR-coded vessel batteries can help retrieve history and model-specific matrices.
WHY IT MATTERS
Capacity is the practical health signal
The Spectro CM-24 tests battery health by modeling a battery against a matrix to validate Minimum Operational Reserve Energy (MORE) based on capacity, the leading health indicator. The 30-secong test is non-invasive. The pass/fail level for starter batteries on trucks is usually set to 50%. A PASS gives a grace period to next service; FAIL calls for replacement even if cranking is still strong. The Spectro CM-24 comes with a matrix of choice. Other matrices can be downloaded from the Matrix Library by the CadexCloud, a web app that also stores test results and vehicle numbers to share with owners and fleet supervisors. Batteries in commercial vessels can be QR-coded to review historic reading and download model-specific matrices by scanning. This feature turns the Spectro CM-24 into an open platform to test virtually any battery.

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.
