Understanding the Technology

The CTEK MXT 4.0 uses adaptive multi-stage charging logic, which adjusts charge current and voltage dynamically based on the battery's real-time condition — a process known as IUoU charging. Unlike trickle chargers, its patented desulphation pulse breaks down lead sulphate crystals that form during prolonged inactivity — a common issue in Indian fleets during festivals or extended shutdowns. The float maintenance stage ensures zero overcharging risk, extending battery life significantly in India's high-temperature climate.
