Understanding the Technology

The MXTS 40 uses adaptive pulse charging — an 8-step algorithm that monitors voltage and current in real time, adjusting output to prevent overcharging and battery degradation. Unlike simple trickle chargers, its desulphation mode dissolves lead-sulphate crystals that build up in neglected or deeply discharged 12v battery charger applications. The Supply Mode function stabilises output voltage independently of battery state, making it safe for sensitive ECU and CAN-bus systems found in modern Indian vehicles. This is the standard used by authorised OEM workshops globally.
