CTEK PRO25 CiC EU 40-480 Professional 12V 25A Automatic Battery Charger for Lead-Acid & Lithium

Delivering a robust 25A charge current, the CTEK PRO25 CiC is engineered for professional workshops and demanding vehicle maintenance. This fully automatic charger handles both lead-acid and lithium-ion batteries with precision.

Overview

The PRO25 CiC is a 12V automatic battery charger designed for professional use. It supports lead-acid batteries (Wet, MF, Ca/Ca, AGM, GEL) from 40 to 500 Ah and LiFePO4 batteries from 30 to 450 Ah. With an 8-step charging algorithm for lead-acid and a 7-step algorithm for lithium, it ensures optimal charging and battery care. The charger operates on 220-240 VAC, 50-60 Hz input and features an IP44 rating for protection against splashing water. It includes a built-in temperature sensor for automatic compensation, spark-free operation, reverse polarity protection, and short circuit proofing. Special modes include RECOND for reconditioning deeply discharged lead-acid batteries and SUPPLY for use as a stable power supply. The unit is fan-cooled with an efficiency greater than 89% and ripple below 4%. AC and DC cables are each 2 meters long.
