CTEK (56-304) Comfort Connect Extension Cable, 8.2 Feet

Car charging

Nice addition to the charger. Better than playing with extension cords. Very good quality wire and connectors.

Bought this together with a NOCO GC004 X-Connect extension cable. After some DIY grafting, the CTEK charger can hook up to some NOCO accessories and vice versa. The CTEK extension wire is a thinner gauge compared to the NOCO wire though, and this CTEK extension cable does warm up slightly under a full 10A charging current.

It does exactly what I wanted, not have to lift the cover to get to plug it in. It would be nice if it can shorter, nothing zip ties cant fix.

needed extension cable for battery charger/maintenance...no problems...extension cable doesn’t impede charger/maintenance process.....

Works perfectly with charger as an extension cable.

Does what it’s supposed to do. Quick and easy to connect. Ctek’s Comfort Connect System click is as reassuring as it is mistake proof. I do wish the shielding was thicker or at least matched the quality of the Chargers themselves which would make for a truly seamless extension. As it is, I would still buy it again.

Just what I needed, purchased a CTEK 560352 to connect to the car battery, mounted the CTEK Battery Tender on the wall close to the AC outlet, and used the extension cord to connect the two. Made cable management a breeze, the added resistance load due to the longer cable was a concern but the Battery Tender so far has been able to cycle through its various charging/tender modes without any issues. Will keep an eye on the tender to see if the longer cable has any effects in regards to longevity.

I bought two of these cables so I can charge my battery while my truck sits in my driveway. I use one extension when I can get close enough to the overhead door, I add the second when it is a little further back (leaving room to get my trash / recycling cans and other stuff in and out of my garage). So far both work as intended, and no problems when using two extensions together.

Works for me flawlessly for about 4 to 5 months when it’s suddenly stopped working. After reading several other posts and questions on this product and see if like you have a certain type of mechanical grease you apply it to the metal ends, and the project will start working again flawlessly. If you don’t own mechanical grease, then that’s another added cost. They should’ve included a small tube of the mechanical grease with this product or the original product instead of getting mechanical grease for this product. I went ahead and got another type of extension cord for battery minders, that’s attached to my vehicle, which worked flawlessly for several years without meat of mechanical Greese. I will save this product in a drawer, hoping to get mechanical grease one day until then it will not work. Only way I would increase my rating from a two star to a five star would be if they do include some type of mechanical grease which is needed or put in bedded lettering. That should only be used indoors.
