Why Trust the CTEK MXTS40 Battery Charger?

  • Reliable and precise 8-step charging process that extends battery life
  • Safe power supply mode with fine incremental voltage control to protect sensitive vehicle electronics
  • Automatic parallel load compensation maintains consistent voltage and amperage during diagnostics or reprogramming

Best for

  • Automotive and heavy vehicle workshops that require dual voltage charging and power supply
  • Users needing fast, safe battery charging combined with diagnostic and reprogramming support
  • Maintaining a range of battery types including AGM, Ca/Ca and GEL

Not ideal for

  • Casual or infrequent users with small 6V batteries or light maintenance needs
  • Outdoor use without protection, as it has an IP20 rating limiting dust and water resistance
  • Users seeking plug-and-play chargers without manual voltage control or fine adjustment options

Precise Voltage Control for Complex Procedures

The MXTS40’s selectable power supply offers finely graduated voltage output settings — 0.4 volt increments for 12V mode and 0.8 volt increments for 24V. This enables technicians to perform complex diagnostics, repairs, and reprogramming on modern vehicles with confidence, protecting sensitive electronics from voltage spikes or fluctuations.

A multilingual LCD screen provides clear, real-time feedback on voltage and charging status, enhancing usability in busy workshop environments.

Fast, Fully Automatic 8-Step Charging

Designed to keep batteries in optimal health, the MXTS40 runs a comprehensive 8-step charging cycle automatically. This process effectively reconditions batteries and guards against common issues such as sulphation or undercharging.

  • BOOST mode specialised for safely recovering deeply discharged lead-acid batteries
  • Temperature compensation automatically adjusts charging current per ambient conditions
  • Low 2V start-up threshold allows safe charging of very flat batteries

Built Tough for Workshop Demands

The MXTS40 is constructed with durability in mind — its rugged design and reliable performance make it ideal for the demands of professional vehicle workshops. While its IP20 rating advises against direct exposure to dust or moisture, it is perfectly suited to typical indoor workshop settings.

CTEK backs this robust build with a 2-year warranty, demonstrating confidence in product longevity and reliability.
