Understanding the Technology
The Comfort Indicator Eyelet uses a passive voltage-sensing circuit to continuously read your lead-acid battery's state of charge (SoC) and display it via a tri-colour LED — no external power source or Bluetooth required. Unlike handheld multimeters, this permanent eyelet connection delivers real-time open-circuit voltage readings directly at the terminal. It is engineered to the same standards as CTEK's professional-grade automotive charger accessories, ensuring accuracy even under Indian voltage fluctuation conditions.
