Understanding the Technology

CTEK's 8-step adaptive charging algorithm monitors battery state continuously, applying controlled desulphation pulses to dissolve lead-sulphate crystal build-up — a common problem in Indian vehicles left unused during long monsoon or summer periods. The constant-current/constant-voltage (CC/CV) charging method ensures no overcharging, extending battery service life significantly. Supply Mode delivers a regulated DC output, making it safe for modern vehicles with sensitive CAN-bus electronics during diagnostic work.
