Cadex Spectro Modular

The Battery specialists at Cadex have delved into the world of AI with their new Spectro Modular handheld rapid battery tester.

The Spectro Modular utilises a non-invasive method called Electrochemical Impedance Spectroscopy (EIS), provide the capacity, CCA and SoC of starter batteries.

Whilst EIS-based analysis has been around for decades, and usually housed in large & cumbersome wheeled cabinets, the interpretation had been quite a manual process. With the new AI based matrix system the Spectro Modular now puts all of those smarts into the palm of your hand.

Spectro Battery Tester ImageDesigned to be used in conjunction with a smart device or tablet (HOST) and through a WebApp called Cadex Link, the Spectro Modular assesses the battery SOH and displays the results on your device. And when used in conjunction with the optional Cloud Analytics services, enables users to track battery fleet performance to ascertain remaining useful life (RUL) to reduce downtime caused by battery sudden failure.

Featuring a 5Ah Lithium Ion internal battery, capable of up to 250 tests before requiring recharging, the Spectro Modular is perfect for mechanical workshops, battery retailers, vehicle fleet managers, and mobile service vehicles. The advanced capabilities also make this unit suitable for academic research labs, similar scientific entities or in manufacturing / quality control to check product consistency and much more.

Suitable to test: Flooded, Sealed, VRLA, AGM, GEL, EFB Sizes: 300 – 1250 CCA, and 55 – 250 (27-125Ah) RC
