CTEK Comfort Connect Extension Cable 8.2 ft — Weatherproof quick‑connect cable for CTEK chargers

The CTEK (56-304) Comfort Connect Extension Cable is an 8.2-foot, weatherproof extension that lengthens the reach of compatible CTEK battery chargers for easier, safer access.

If your garage, workshop, or vehicle layout keeps a battery charger out of easy reach, this extension cable adds extra length without changing the charger’s connection type. Built for compatibility with a wide range of CTEK models, the Comfort Connect extension preserves the secure, quick-connect interface you’re already using while giving you more placement flexibility.

How does the CTEK extension make charging more convenient?

The 8.2-foot length gives you room to position the charger in a dry, safe spot while still reaching the battery terminals. That reduces the need to move heavy chargers or awkwardly route cables across the shop floor.

• 8.2 feet (approx. 2.5 meters) of added reach for flexible placement
• Maintains the original Comfort Connect quick-disconnect interface
• Weatherproof connections allow use near vehicles and outdoors

Is the extension durable and safe for workshop use?

The Comfort Connect extension uses weatherproof connections and quality materials to stand up to typical garage and outdoor conditions. While not a substitute for heavy-duty industrial cabling, it is built to the same connector standard as CTEK chargers for consistent, safe performance.

• Weatherproof connector housings protect contact points from moisture
• High-quality cable construction resists wear from regular handling
• Quick-connect design reduces risk of loose or incorrect connections

How do I use and store the extension safely?

Connect the extension between your CTEK charger and the accessory or battery lead, ensuring connectors click securely. After use, keep the cable dry and coiled without tight kinks to prolong service life.

• Attach firmly until the Comfort Connect latch engages

• Store in a cool, dry place out of direct sunlight
