CTEK PRO25S NA – Advanced 12V 22A Battery Charger & Power Supply for Automotive Professionals
The CTEK PRO25S NA is a high-performance, fully automatic 22A battery charger and power supply engineered to meet the demands of modern automotive workshops and showrooms. Combining advanced charging technology, superior safety features, and robust design, the PRO25S delivers efficient, reliable power for any 12V battery, including lithium (LiFePO₄, Li-Fe, Li-iron, LFP) and all types of lead-acid batteries.
With its powerful 22A output, the PRO25S ensures safe, fast, and adaptive charging for batteries from 40Ah to 500Ah (and 30Ah to 450Ah for lithium). The integrated lead-acid reconditioning mode restores deeply discharged batteries, extending service life and performance. In SUPPLY mode, it provides stable power support during diagnostics, software updates, and fault-finding without risk to sensitive electronics.
The PRO25S ensures ultra-clean voltage and current delivery with minimal ripple, protecting the vehicle’s onboard systems and delicate electronics. Its built-in temperature sensor automatically adjusts voltage levels for optimal charging in any condition. Designed with professionals in mind, it’s lightweight, portable, spark-proof, and reverse-polarity protected, with a rugged impact-resistant casing for demanding workshop environments.
