Understanding the Technology
The CTEK CT5 Start-Stop uses an advanced pulse charging algorithm across its 8-step cycle, which includes desulphation, soft start, bulk charge, absorption, and float maintenance stages. This multi-stage process is critical for AGM and EFB battery chemistry used in modern start-stop systems, where standard 12V car battery chargers can cause permanent cell damage. The charger's microprocessor continuously monitors battery state, adjusting current delivery to ensure full capacity restoration without overcharging — a vital feature given India's frequent power fluctuations.
