Understanding the Technology

The CTEK MXS 3.8 uses a multi-stage constant-current/constant-voltage (CC/CV) charging protocol, which conditions the battery plates and prevents sulphation — a common problem in India's high-temperature climate. Unlike basic battery chargers for cars that apply a fixed charge, this smart 12 volt battery and charger system continuously monitors internal resistance and adjusts output accordingly. This is precisely why it is trusted across all types of charger categories for both two-wheelers and four-wheelers.
