CTEK's Comfort Connect System Makes Charging Easier


Our chargers are used by many people around the world in a variety of different applications. Everyone uses their charger in a slightly different way depending on where they are and what vehicle they are charging. CTEK has a wide range of accessories for your convenience. Our goal is to provide you accessories for ease of charging in any situation. 

Every CTEK Charger comes with clamp leads for a quick connection to the battery as well as eyelet leads for a more permanent connection if the battery is difficult to access.

CTEK’s easy-fit Comfort Connect system ensures both the clamp leads and eyelet leads can be connected with ease. The Comfort Connect system also allows any CTEK charger to seamlessly connect to a wide array of additional CTEK accessories, each sold separately.

Use of the CTEK Comfort Indicator is a simple way to connect and monitor the charge voltage of your battery. All Comfort Indicator products utilize a simple ‘traffic light’ system to show the battery’s charge level so that you can know when to charge your battery to avoid no start situations and helps you to keep your battery charged to extend battery life.

  • RED means the battery charge is below 12.4V and it’s definitely time to charge your battery NOW.
  • YELLOW means that the battery charge is between 12.4 and 12.65V and it’s time to start thinking about charging your battery
  • GREEN means that your battery charge is at 12.65V or above and is in fine shape, no need to charge.

Note: the most accurate battery voltage reading comes about 2-3 hours after you have used your vehicle and the Comfort Indicator will not recognize battery voltage under 3V.
