CTEK PRO25S Battery Charger - 50-60 Hz - 12V

Why the PRO25S stands apart

• Smart charging meets professional reliability: Fully automatic operation adapts to each battery’s needs, delivering a fast, safe charge from start to finish.
• Dedicated lithium mode for 12V Li‑ion chemistries: Supports LiFePO4 and other 12V lithium batteries (LiFePO4, Li-Fe, Li-iron, LFP) with a tailored charging profile.
• Extensive compatibility: Works with lead-acid formats from 40 Ah up to 500 Ah and lithium packs from 30 Ah to 450 Ah, making it versatile for a wide range of vehicles and applications.
• Lead-acid reconditioning program: A built‑in routine to restore life to marginal or flat batteries, helping you avoid unnecessary replacements.
• SUPPLY mode for diagnostics: Keeps the battery stable during fault-finding or system diagnostics, safeguarding vehicle electronics.
• Low ripple, spark‑proof, reverse-polarity protected: Protects both battery and vehicle electronics while reducing risk during connection.
• Integrated temperature sensor: Optimizes charging levels to maximize final capacity and battery longevity.
• Rugged, portable design: Lightweight yet impact‑resistant, ready to handle the rigors of a busy workshop or showroom floor.
• Safety first: Extra protection features ensure safe operation for you and the battery, every time.
• User-friendly, professional workflow: Spark-free connections and simple setup make it easy for technicians to get the job done quickly.

Who benefits from the PRO25S

• Automotive service centres and workshops that service a mix of vehicles with conventional and lithium 12V batteries.
• Showrooms and vehicle displays where batteries must be kept in peak condition without risking electronics.
• Mobile technicians who need a reliable, portable charging solution that can handle diverse battery chemistries on the road.
• Fleet maintenance teams responsible for long-term battery health and cost control.

What problems it solves

The PRO25S tackles common battery challenges without fuss. It reconditions aging lead-acid packs to extend service life, revitalizes flat batteries to reduce replacements, and provides a stable power source during diagnostics without upsetting sensitive vehicle electronics. For lithium batteries, it offers a dedicated mode that respects chemistry while delivering reliable charging performance. When you’re diagnosing, testing, or showroom-keeping vehicles, the SUPPLY mode keeps systems powered without overcharging.

Practical use cases in the real world

• During a showroom battery test, let the PRO25S maintain a healthy charge while you run diagnostic software.
• In the workshop, quickly recover a marginal 12V lead-acid battery with the built-in reconditioning program to avoid premature replacement.
• On the service bay, charge a 12V LiFePO4 pack from 30 Ah to 450 Ah with a profile that protects the cell chemistry and extends pack life.
• Perform diagnostics on vehicles with delicate electronic systems—SUPPLY mode ensures continuity without voltage spikes.
