Understanding the Technology
The CTEK Pro25S uses multi-stage adaptive charging with a pulse desulphation algorithm that breaks down lead sulphate crystals — the primary cause of battery failure in Indian heat conditions. Its constant current / constant voltage (CC/CV) topology ensures LiFePO4 cells receive a precisely controlled charge, preventing overcharge damage. This makes it a superior 25A battery charger for professionals managing diverse vehicle fleets including SUVs like the Kia Seltos and heavy commercial vehicles.
