CTEK PRO25SE Battery Charger - 50-60 Hz - 12V - 19.6ft Extended Charging Cable

The CTEK PRO25SE Battery Charger is a professional-grade 22A charger and power supply designed to keep a busy workshop running smoothly. With extended 19.6 ft (236 inch) charging cables, you can mount the unit on ramp-posts or in work bays for instant access, reducing walk-time and speeding up service workflows. It works with any 12V vehicle battery, including lithium systems, making it a versatile centerpiece for fleets, garages, and showroom service bays.

Why the PRO25SE stands out

Designed for real-world workshop needs, the PRO25SE blends high efficiency with smart technology to deliver a safe, fast, and battery-friendly charge that’s tailored to each pack. Its dedicated lithium mode (for LiFePO4, Li-Fe, Li-iron, LFP) and a robust lead-acid program mean you don’t have to juggle multiple chargers—this unit covers it all in one compact, rugged package.

Key features and concrete benefits

• 22A charging power + dedicated supply mode: Provides fast, controlled charging while also serving as a stable power source during diagnostics or fault-finding work.
• 12V compatibility with a wide battery range: Supports WET, EFB, MF, Ca/Ca, AGM, GEL, and LiFePO4 12V lithium packs, from 40 Ah up to 500 Ah (30–450 Ah for lithium).
• Advanced safety with low ripple: Low voltage and current ripple protects delicate vehicle electronics and the battery itself, reducing risk during charging and diagnostics.
• Dedicated lithium mode + lead-acid reconditioning: Optimizes charge for lithium packs and includes a program to restore and refresh aging lead-acid batteries, extending service life.
• Built-in temperature sensor: Adjusts charging to maximize performance and prevent overheating, even in demanding workshop environments.
• Spark-proof, reverse-polarity protected, and fully automatic: Easy to connect with fewer errors, protecting both technician and battery.
• Permanent installation capability: Casing includes mounting points for on-ramp posts or in-work bay installation, plus a wall hanger and bracket for flexible setup.
• Rugged, portable design: Lightweight, impact-resistant housing built to withstand busy shop floors, yet simple to move when needed.
• Ready for professional environments: 50–60 Hz operation, 110–120 VAC input, and a 2-year warranty for peace of mind in high-use settings.

Perfect use cases in the real world

• Fleet maintenance bays: Keep a variety of 12V batteries—including lithium-equipped models—charged and ready between diagnostic sessions.
• Diagnostics and fault-finding: Use SUPPLY mode to support the battery while you run system checks without drawing down voltage or triggering faults in sensitive electronics.
• Showroom demonstrations: Demonstrate reliable charging behavior with a visible, consistent power source during customer walkthroughs.
• Workshop efficiency: Long cables allow charging without relocating vehicles; permanent installation options reduce clutter and speed up daily routines.
• Battery life extension: The lead-acid reconditioning program can revive older batteries, reducing replacement frequency and total cost of ownership.

Who benefits most

Professional technicians, fleet service centers, and dealership service bays will gain the most from the PRO25SE. It’s ideal for shops that service a mix of 12V lead-acid and lithium batteries, need reliable diagnostic power, and require flexible installation options to fit their space.
