Understanding the Technology
The CTEK Pro25S uses multi-stage adaptive charging, automatically adjusting current and voltage across eight distinct phases — including desulphation, bulk charge, absorption, and float maintenance. This constant-current/constant-voltage (CC/CV) methodology maximises battery longevity and is particularly effective against sulphation damage common in India's high-temperature climate. The result is a smarter, safer automotive charger that protects your investment rather than simply pushing current into a battery.
