CTEK Smarter Chargers Make Safety a Priority

Charging car batteries can make a lot of drivers nervous. Are the cables wrong? Will there be sparks? Could I be in physical danger? CTEK’s Smarter Chargers are precision designed with safety in mind.

CTEK Smarter Chargers have a spark-free, short-circuit-proof design that incorporates a feature preventing reverse polarity.

Dangers of Reverse Polarity

When that happens, there’s the potential for a battery to explode. Using the wrong terminals could damage a battery to the point where it can no longer hold a charge. Damaged batteries may also leak acid, making them a hazard to dispose.

Using the wrong terminals not only jeopardizes your battery, it also can hurt your vehicle. Wires may melt or your electronic components could get “fried.” 

CTEK's Commitment to Safety

CTEK’s Smarter Chargers make safety a priority. The charger knows if you attach one end to the wrong battery post and will not operate if it is attached incorrectly, you don’t need any special knowledge to use them. 

Conveniently, the red alarm light on the charger alerts you if it wasn’t attached correctly so that you can get it connected properly.

Our patented pulse maintenance technology also means that CTEK battery chargers can be connected to the battery for months at a time, so you can simply connect and forget.

Our Smarter Chargers constantly communicate with the battery throughout the whole charging process and they only supply charge depending on the battery’s exact needs. This prevents over- or undercharging, which can reduce the battery’s lifespan.hands holding a CTEK battery charger with an open hood of a car in the background showing the engine
