Understanding the Technology

The CTEK MXS 3.8 uses pulse charging and desulphation technology to break down lead-sulphate crystals that accumulate on battery plates — a common problem in India's hot climate. Unlike a simple battery charger for 12v battery that pushes constant current, this charger dynamically adjusts voltage and amperage across eight defined stages. This multi-stage approach, used by def in diesel and petrol vehicle manufacturers globally, extends battery life significantly. It is the reason CTEK is the preferred 12 volt battery and charger solution among professional workshops worldwide.
