WIN! CTEK MXTS 40 battery charger

WIN! CTEK MXTS 40 battery charger

CVW has teamed up with CTEK to provide lucky readers with the chance to win the MXTS 40 battery charger.

With one in four commercial vehicles arriving in the workshop with a battery problem, it’s more important than ever to ensure that the battery is supported if you are undertaking repairs, testing electrical circuits, carrying out diagnostic procedures, flash programming ECUs or programming vehicle keys. Using a battery support unit will protect the battery against failure, saving technician time, ensuring against programming failures and preventing possible costly damage to the ECU.

The CTEK MXTS 40 is a powerful, compact and robust 40A battery charger and support unit for use with both 12V and 24V batteries.

This simple-to-use, electronically-safe unit provides rapid charging for all chemistries. It’s a powerful eight-stage charger that will provide optimum charging in the shortest possible time. With selectable modes for all battery types including calcium, gel, and AGM, it is said to ensure that a safe, fast charge is delivered to exactly meet the needs of the individual battery chemistry. The ‘Recond’ mode can also be selected to restore deeply discharged batteries which would normally be discarded.

Equally suited to battery support, the MXTS 40 provides a range of highly accurate, selectable and constant voltage settings to avoid ECU damage due to voltage fluctuation during programming. It can supply up to 40A of clean and constant current (20A in 24V mode), protecting against disruption to the diagnostic process. The charger has a voltage range of 13.6 to 14.8V in 12V mode and twice this in 24V mode.

It can also be used as a secure power source if the battery needs to be disconnected from the vehicle. The user interface provides essential information clearly and simply, with the eight-stage charge progress indicator LEDs being complemented by an additional OLED display that gives read-outs of important charge parameters, including current, voltage and amps charged.

Fully automatic, spark proof and reverse-polarity protected, the MXTS 40 can be connected to the battery without removing it from the vehicle.


To be in with a chance of winning this great prize, all you have to do is answer the following question:

How many amps does the charger supply when used at its maximum capacity?
