Description: The CTEK PRO25S (40-328) is a 25 amp battery charger and power supply built for professional automotive workshop use. It charges and maintains 12V lead-acid batteries, including WET, MF, Ca/Ca, AGM, EFB, and GEL types, with capacities from 40 to 500 Ah. It also works with 12V lithium LiFePO4 batteries from 30 to 450 Ah. The charger uses a fully automatic 8-step charging cycle and includes a RECOND mode to help recover deeply discharged lead-acid batteries. A lithium wake up mode is included for lithium batteries with under voltage protection. The unit also functions as a 12V power supply, delivering up to 25A at 13.6V to support the vehicle during diagnostic work, code reading, and electrical testing without disconnecting the battery. Automatic parallel load compensation keeps power supply output steady even when an additional load is placed on the battery. A built-in temperature sensor adjusts charging for ambient conditions from -20°C to 50°C. The unit is compact and portable, with a low 2V start voltage and low ripple output, and carries an IP44 degree of protection. It comes with a 2 year warranty.
