Description

Product Description

The CTEK Pro25S is a professional-grade automatic charger delivering 12V 25A output — the most powerful automotive charger in its class. This battery charger supports both Lead-Acid and LiFePO4 chemistries, built for Indian workshops, fleet operators, and serious enthusiasts. Handles India's voltage fluctuations, summer heat up to 50°C, and monsoon humidity without issue.

Features & Benefits

  • 25A Fast Charging: Dramatically cuts turnaround time in high-volume Indian service centres.
  • Dual Chemistry Support: Charges AGM, GEL, WET, Ca/Ca, and LiFePO4 — one unit replaces several chargers.
  • RECOND Mode: Revives deeply discharged batteries after long monsoon-season storage.
  • Power Supply Mode: Stable 13.6V output protects ECU electronics during reprogramming.
  • Temperature Compensation: Accurate from -20°C to +50°C — covers every Indian climatic zone.
  • IP44 Weather Resistance: Dust and splash-proof, ideal for humid Indian garages.
  • Surge & Spark Protection: Reverse-polarity and short-circuit safe on India's unpredictable grid.

Understanding the Technology

The CTEK Pro25S uses an advanced 8-step adaptive charging algorithm that analyses battery condition before applying current — preventing overcharge and sulphation, the leading cause of battery failure in India's extreme climate. Its CCCV (Constant Current / Constant Voltage) topology ensures LiFePO4 cells receive chemistry-specific charging profiles safely. This is why professional car battery charger users and fleet managers prefer CTEK over generic alternatives.
