Product Description

CTEK CT5 Start/Stop Battery Charger, suits Vehicles, 5 Year Warranty. The CT5 START/STOP battery charger and maintainer has been specially designed to charge and maintain batteries in Start/Stop vehicles.

Start/Stop technology is great for the environment but it can put a considerable strain on your battery, especially if it’s in an older car. By keeping the battery fully charged, you can take full advantage of all the Start/Stop technology benefits, such as better fuel efficiency and lower CO2 emissions. If you only make short journeys, use the CT5 START/STOP once a month to keep your battery in peak condition. And if you’re going away on holiday, just connect the charger to the battery to make sure your car’s ready to go when you return.

  • Fully optimized for cars with Start/Stop technology, e.g. AGM and EFB batteries
  • No buttons to press – fully automatic charging
  • 5-year warranty
  • Simple to use with an easy to understand display
  • Reverse polarity protected

Customer Reviews

high quality product Review by
Bought a new vw golf R recently. Then went off on a 1 month camping trip around tassy in my troopy and was advised that, as the battery is now such an important component in modern engine management systems a good quality trickle charger is preferred. The CTEK C5 was recommended. It was easy to install - basically set and forget and it worked a treat, just what I needed.
