Understanding the Technology

The CTEK MXT 4.0 uses multi-stage adaptive charging technology, where each phase — including desulphation, bulk charge, absorption, and float maintenance — is automatically optimised based on battery response. This pulse maintenance approach prevents overcharging and sulphation, the two leading causes of premature battery failure in India's extreme heat and stop-start traffic conditions. Unlike basic trickle chargers, this automotive charger actively monitors battery health throughout the cycle.
