A charger built for the workshop
The CTEK PRO25S is a professional-grade 12V battery charger and power supply, built for auto shops, dealerships, and demanding users who need far more power than a consumer charger.
Lead-acid and LiFePO4, with a real lithium wake function
Its versatility is its main strength: it handles both lead-acid batteries (flooded, Ca/Ca, AGM, EFB, gel) from 40 to 500Ah and lithium LiFePO4 batteries from 30 to 450Ah, thanks to a dedicated patented system that restores, charges, and maintains lithium without degrading it. Its wake function even revives lithium batteries dropped into low-voltage protection, a case many chargers simply give up on.
RECOND and SUPPLY, two workshop functions
The PRO25S combines several profiles in one unit: a RECOND reconditioning and desulfation program to bring a tired lead-acid battery back to life, and a SUPPLY mode that turns it into a stabilized 12V power supply, very useful in a workshop to maintain the vehicle's memory (ECUs, coding) during diagnostics or a battery swap without disconnecting. Its 8-step charge adjusts automatically via an external temperature sensor, staying effective from -20°C to +50°C.
IP44 and compact, but a short cable and reduced warranty
It's IP44 protected against splashes and dust, spark-free and protected against reverse polarity, with a fan to dissipate the heat generated by its power, unlike small passive, silent maintainers.
Who the PRO25S is for
For occasional home use, a NOCO Genius5 or Genius10 is plenty; for a professional or enthusiast juggling several vehicles, heavy batteries, and lithium, the CTEK PRO25S is built for intensive use.
