We’re excited to announce that Defy Diagnostics Partners with GYS, and is now a direct importer and distributor of GYS products, including their world-class battery support units, chargers, and boosters—plus professional-grade induction heaters.
Why This Matters for You
If you’re performing diagnostic scans or ADAS calibrations, you already know that stable battery support isn’t optional—it’s essential. GYS battery support units deliver the clean, consistent power your shop needs to complete programming, scanning, and calibrations without risking voltage drops, data corruption, or failed procedures.
By partnering with GYS, we’re able to offer:
- National availability – Get the tools you need shipped directly, anywhere in the U.S.
- Better pricing – No middleman. Direct importer status means savings go to you.
- Full warranty support – Backed by both Defy Diagnostics and GYS.
- Bundle-ready solutions – Seamlessly pair GYS battery units with your TEXA diagnostics and ADAS calibration systems for a complete professional setup.
Beyond Battery Support
Our lineup doesn’t stop at chargers and support units. GYS also delivers powerful boosting technology, including battery-less super-capacitor boosters. These next-generation units provide instant starting power without relying on an internal battery—offering unmatched reliability, faster recharge cycles, and a service life that outlasts traditional boosters.
And for shops tackling tough jobs, we’re also expanding into GYS induction heaters—another indispensable tool for modern repair operations.
