Maximizing Vehicle Battery Performance Swedish company CTEK AB invented the latest smart car charger for consumers almost 20 years ago. CTEK chargers use unique and patented technology to ensure batteries are charged easily, safely and optimally maintained. CTEK chargers can also monitor battery health and take appropriate action to maximize battery capacity and life.

Battery-related issues are the number one reason for US auto breakdown assistance callouts. Regular use of a CTEK charger will keep your battery in optimum condition and save you the cost, inconvenience and frustration of unplanned battery failure. For less than the price of a new battery, CTEK battery chargers are a worthwhile investment for your car, truck, boat, motorcycle, ATV, lawn and garden equipment, and more.

Reliable in all conditions, the Swedish-designed CTEK Smart Charger is extremely rugged and weather resistant. Most chargers have an operating temperature range of +122 degrees Fahrenheit and best stay between -4 degrees Fahrenheit and 1 degree Fahrenheit. There are also CTEK "Polar" chargers with features such as special cables that work in very cold conditions and unique charging parameters.

CTEK battery chargers are shockproof, weatherproof, dustproof and fully approved for year-round outdoor use (IP44-IP65). So no matter where you park your CTEK battery charger will always be ready to go.

prolong battery life
Regular use of the CTEK battery charger has been proven to extend vehicle battery life by up to 3x.

Vehicle batteries are optimally charged and maintained through a series of charging stages (4, 6, 8 steps, depending on unit) to improve battery performance and extend battery life.

CTEK battery chargers are capable of desulphurizing, charging, reconditioning and maintaining all types of vehicle batteries including wet/flooded, calcium, gel, lithium (with CTEK lithium chargers) and the latest Start-Stop AGM and EFB technologies. increase. A patented float-and-pulsate maintenance strategy ensures that once fully charged, the battery is safely maintained at maximum capacity by the charger indefinitely, maximizing battery life.

Many CTEK battery chargers have a RECOND feature. This function, combined with the desulfurization function, can restore the capacity of many batteries that would otherwise not be able to accept charging. It can also rejuvenate heavily discharged batteries.


Trustworthy OS Supplier
CTEK manufactures battery chargers for the world's premium automakers including Audi, Bentley, BMW, Corvette, Ferrari, Jaguar, Koenigsegg, Lamborghini, Maserati, McLaren, Mercedes, Porsche and Rolls-Royce. These well-known and selective OE customers trust the superior quality, value and technical performance of CTEK chargers to sell them under their own brand.


Advantages of low ripple
CTEK battery chargers and maintainers produce very clean voltages and currents that are safe for batteries and vehicle electronics, regardless of how long the charger is connected.

Current ripple in excess of 5%, which is common in less advanced battery chargers, will cause the positive battery electrode to age, while high voltage ripple can harm sensitive and expensive vehicle electronics. . Why is the risk of using a "CTEK imitation" charger an issue?


Safe for vehicles and users
The CTEK battery charger's advanced electronics ensure that it is extremely safe to use. Chargers, for example, feature spark and reverse polarity protection. If the clamps are accidentally reversed or touched, the charger will detect the error, stop working, and display an error light to indicate the fault. All CTEK charger safety features are developed to protect you, your battery, and your vehicle.
