Spectro CA-12
Non-invasive battery tester Spectro reads capacity with multi-model electrochemical impedance spectroscopy (EIS). A 'pass' gives a grace period; 'fail' requests replacement even though cranking may still be strong.
- Reads lead acid and Li-ion
- Unit stays cool during test
- Range 12V, 25-100 Ah
- Reads capacity, the leading health indicator
Spectro Technology
Spectro™ estimates battery capacity by taking a mirror image of the battery in Electrochemical Impedance Spectroscopy (EIS).
The test is non-invasive and takes about 30 seconds.
EIS resembles face recognition
Complex EIS modeling assesses capacity, CCA and SoC
Frequency scan produces a Nyquist plot that is modeled against a matrix to extract battery capacity, CCA and SoC. Test accuracy is governed by the matrix.
U.S. patent 7,072,871,
U.S. patent 6,778,913
Automotive Applications
Spectro™ verifies starter batteries at ports, checks warranty and provides after-sales service. Capacity is the leading heath indicator.
Modus Operandi
Select battery chemistry and enter voltage, capacity and CCA.
The battery must have a minimal state-of-charge of 50%.
