Understanding the Technology

The MXTS 40 uses adaptive multi-step charging — automatically cycling through analysis, bulk charge, absorption, and float maintenance phases to maximise battery lifespan. Its pulse maintenance technology prevents sulphation, a common cause of premature battery failure in India's hot climate. The battery charger for 12v battery and 24V applications uses a switch-mode power supply, making it highly efficient and stable even during grid voltage fluctuations typical across Indian towns.
