Brand History:

The CTEK story starts over 30 years ago in Vikmanshyttan, a small village in Dalarna in Sweden. This is where our founder – Swedish inventor Bengt Wahlqvist – created the first ever battery charger to use electronic pulse technology.

And, thanks to Bengt’s technical expertise and perseverance, the world’s first ‘smart’ battery charger was born.

CTEK acquired Chargestorm, Scandinavia's largest producer and developer of electric vehicle (EV) charging solutions; a reflection of our strong commitment to entering this fast-growing sector. With Chargestorm’s strong product base, cutting edge technology and expertise in EV and CTEK’s global presence and reputation for quality and innovation within battery management, we are already taking the global EV market by storm. More about the merger of CTEK & Chargestorm.

Product Description:


Automatic charging and maintenance for vehicle and motorcycle batteries, with reconditioning mode

The MXS 5.0 is an advanced microprocessor controlled battery charger which gives unrivalled performance for lead acid batteries from 1.2-110Ah. It comes with automatic temperature compensation built in which ensures the best charging performance, even in the most extreme conditions. The MXS 5.0 also includes battery diagnosis to establish whether your battery can receive and retain a charge, patented automatic desulphation program, an AGM option which maximises the performance life of most Stop/Start batteries and a special Recond mode for reconditioning deeply discharged batteries. The MXS 5.0 uses CTEK’s patented float/pulse system, which is the most efficient maintenance mode when a battery is connected for long periods.


  • Charges batteries up to 110A

Charging category:

AC charging


Back current drain*:

Corresponding to less than 1 Ah/month


Back Current Drain TEXT:

*) Back current drain is the current that drains the battery if the charger is not connected to the mains. CTEK chargers have a very low back current.


Battery voltage:

12 V


Battery chemistry:

Lead acid (AGM, GEL, EFB, MF, CaCa)


Ambient operating temperature:

Less than 4 %


Ripple TEXT:

**) The quality of the charging voltage and charging current is very important. A high current ripple heats up the battery which has an aging effect on the positive electrode. High voltage ripple could harm other equipment that is connected to the battery. CTEK battery chargers produce very clean voltage and current with low ripple.
