Why Capacity Matters
A Battery Can Still Start the Engine and Be Nearly Worn Out
Traditional tests can indicate whether a battery can crank an engine, but may not reveal how much usable capacity remains. Spectro Modular measures capacity to expose deterioration that conventional testing can miss.
Core Features
Rapid Results
Results in <30 seconds rather than lengthy discharge testing.
Non-Invasive Testing
Assess battery health without cycling the battery.
Capacity Assessment
Go beyond voltage and conventional conductance measurements.
Compact & Handheld
Portable tester connects wirelessly to a phone, tablet or laptop.
Multi-Application
One device for automotive, heavy-duty, military and industrial applications.
Connected Analytics
Store and analyze test results through CadexCloud.
OPEN API
Integrates with OEM warranty, aftermarket, scan-tool and telematics systems.
Multi-Chemistry Support
Supports lead-acid and lithium-ion battery architectures.

Spectro Auto
Superior Speed and Customer Service
An OEM dealer in Florida leveraged the Cadex Spectro device to great success, improving customer service speed and satisfaction. On peak days, they averaged several hundred in-bound dealer service touch points with clients.
The Spectro device enabled them to streamline their service experience--battery state of health was fully diagnosed for vehicle cranking and reserve capacity including remaining useful life upon intake. This ensured customers got the most life from their battery and faulty batteries were detected before being stranded.

Spectro Monitor
Observe of Battery Health in Field Installations
Spectro Monitor is the only technology capable of reading battery capacity non-invasively. As capacity fade is the most common failure mode, Cloud Analytics calls for replacement when the capacity drops below the user-set threshold.
Spectro Monitor requires a model-specific matrix that Cadex provides by scanning aged batteries of the same model. Applications are UPS and BESS with lead acid and lithium systems up to 48V nominal and 300 Ah.
Nyquist plot discloses information relating to battery capacity, derived by AI.
Spectro BMS
Assessing Capacity by EIS
Spectro BMS assesses battery capacity by EIS, a technology that improves accuracies over coulomb counting. The EIS Direct Drive enables testing larger batteries with low frequency on a compact circuit that incorporates in existing BMS circuits. Test accuracy hinges on the maturity of the matrix. Applications are EVs, UPS, and BESS.
- Current draw during test is 500 mA
- Test time 30 second test; longer with larger batteries
- Frequency scan 2,000 Hz to 0.1 Hz
- Internal battery resistance must be above 500 µΩ

Spectro Explorer
A Snapshot of Battery Health
Spectro Explorer captures the electrochemical evidence of a battery in 30 seconds. The derived Nyquist plots display anomalies, such as low capacity and dendrite growth. The system supports lithium and lead based packs.
- The Spectro Explorer tests Li-ion and lead acid batteries from 3−48V.
- A frequency scan from 2,000−4Hz produces the Nyquist plot shown.
- The Spectro Explorer serves battery manufacturing in QA, acceptance testing, and integrity checking for safety of batteries in micro-mobility.
- Spectro assesses battery capacity with frequency scan from 2,000 Hertz to 4 Hertz (and lower)
- Scan assesses battery performance and requests replacement when low
- A 'pass' gives a grace period to next service; a 'fail' requires immediate replacement
- Internal battery enables 250 tests between charges and stores 1,000 test results
- Communication to host is by Bluetooth or USB; cloud connectivity is by Wi-Fi
- 1 meter (40") test cable; USB recharges internal battery
- D: 182mm (7.16“); W: 96mm (3.78“); H: 47mm (1.85“).430g net (0.94 lb.). comes in transit case
