Understanding the Technology

The MXTS 40 uses adaptive multi-stage charging — a method where the charger analyses battery condition and adjusts current and voltage automatically throughout the cycle. This protects the 12V battery and charger connection from overcharge damage, which is especially critical given India's high ambient temperatures that accelerate battery degradation. The desulphation pulse in the early stage dissolves lead sulphate crystals that accumulate during prolonged storage, restoring capacity in deeply discharged batteries common after the monsoon season.
