Understanding the Technology

The CTEK MXT 4.0 uses multi-stage adaptive charging with a patented desulphation algorithm that dissolves lead-sulphate crystal build-up — the primary cause of premature battery failure in India's extreme heat. Unlike basic types of charger that apply constant voltage, this 12v battery charger-class intelligence (scaled to 24V) monitors battery response at every stage, adjusting current to maximise battery lifespan and safety.
