Dead Car Battery? Don’t Get Stranded in the Cold

CHICAGO, Dec. 21, 2021 /PRNewswire/ — Being stranded in the cold with a dead battery is the last thing any driver wants, but dead batteries are a leading cause of breakdowns in winter months, say the battery experts at CTEK.

Cold temperatures require a battery to use up to twice the normal current to start the engine, an extreme demand that shortens battery life.

"A battery loses as much as 35% in performance when temperatures hit freezing, and up to 50% if temperatures sink below that," said Bobbie DuMelle, Executive Vice President of CTEK North America, the leading global brand in vehicle charging and battery management solutions.

"People think only older batteries are affected by cold weather, but newer batteries are equally vulnerable," explained DuMelle. "Today’s vehicles rely heavily on onboard computers and electronic systems, all of which draw from the battery and can reduce its capacity during the winter months."

In sub-zero temperatures, dealing with a dead battery isn’t just an inconvenience, it’s also a safety risk. Drivers may be left exposed to the elements as they wait for assistance.

For winter peace of mind, CTEK has developed a portable battery charger, the CS FREE, that drivers can take with them and never need to worry about being stranded with a dead battery again.

The award-winning CS FREE uses revolutionary Adaptive Boost technology to gently and safely give a dead battery enough charge to start in 15 minutes.  The CS FREE also has USB-A and USB-B ports to charge phones, computers, tablets and other devices making it the perfect addition to a winter emergency car care kit.

In addition, the CS FREE can be used as a portable charger to top-up your battery charge levels or plugged into a power outlet for battery conditioning and longer term maintenance charging.

Comedian Jay Leno, an avid car enthusiast and host of Jay Leno’s Garage recently added a CTEK CS FREE to his own collection.

The CS FREE, as well as other CTEK products and accessories, are available on Amazon or at
