THE PROBLEM
One weak battery can shorten the whole shift
Floor cleaners often run on deep-cycle battery packs. When one battery fades faster than the others, runtime drops and cleaning schedules become harder to complete. Operators may only discover the problem after the machine stops early.
THE CADEX SOLUTION
Test for usable runtime, not battery age
Spectro CM-24 helps validate Minimum Operational Reserve Energy based on capacity, the health indicator that governs practical runtime. For deep-cycle applications, the pass/fail level is commonly set around 60% to help confirm full-day service or assign weaker packs to lower-demand tasks.
HOW IT WORKS
Find the weak link after service
A 30-second EIS scan estimates capacity and state-of-charge without loading the battery. Measuring leftover charge after service can show whether packs are matched. A well-matched string should remain close in state-of-charge; low performers can be replaced with batteries of similar capacity.
WHY IT MATTERS
Capacity governs battery life and runtime
The source material repeatedly frames the battery as the weakest link and explains that capacity fade should be observed so each battery can be fully used until replacement is needed.

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.
