Understanding the Technology

The CTEK MXT 4.0 uses pulse charging and desulphation technology to break down lead-sulphate crystals that form during deep discharge — a common problem in Indian fleets where vehicles sit idle for extended periods. Its constant-current/constant-voltage (CC/CV) algorithm ensures the battery is never overcharged, extending service life significantly. This is the same technology trusted by professional automotive workshops globally and increasingly by Indian HCV transport operators.
