Understanding the Technology

CTEK's adaptive multi-step charging algorithm continuously monitors state-of-charge (SOC) and internal resistance, adjusting voltage and current in real time. Unlike basic trickle chargers, this automotive charger applies a controlled desulphation pulse to recover deeply discharged lead-acid batteries — a common issue in India due to frequent power cuts and vehicle storage. LiFePO4 compatibility is achieved via a dedicated CC/CV profile that prevents lithium cell damage. This makes the NXT 5 a future-proof investment as EV and hybrid two-wheeler adoption grows across India.
