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

This specialized slender extension cord works perfectly. The ends are idiot-proof and can only mate one way with the charger unit or with other cables. These cables latch securely, but disconnect immediately when pressing a thumb plate. Note that the extension cords are only usable with CTEK chargers and cables. This cord can be slender, because it is carrying a relatively small current from the charger to your car, boat, generator, etc. battery. The less desirable alternative is to use a heavy, thick extension cord from the wall outlet to the charger. This would be necessary because of the greater current going the cord.

Very helpful due to the layout of the power outlets in my garage. Excellent.

awesome product

Its obviously easy to use because it clicks right into the CTEK connectors. But its pricy and the material is stiff and inflexible. They get the job done for me but Id be happier if I felt I had gotten a better value.

Great product. Makes it much easier to charge the battery in my car. I no longer have to worry about parking my car close enough to an electrical outlet for the charging cords to reach my car!

The plug fits perfectly into the existing CTEK charging cable as expected. Not much more to add. If you need additional length in your charging cord, then this is the extension cable to buy.

These extension wires are JUNK. The wire is very stiff and not flexible or pliable. Extension wires are an essential component of any battery tender system. These wires are a deal breaker for any CTEK product. How can CTEK produce such garbage? I have no confidence in the company.

I wish the listing would have noted that the quick connect part of the charging was included AND how long it was. There was only mention of the cable that temporarily clamps to the battery posts, which in most instances I would only need to use on rare occasions. The included quick connect with the charger is plenty long enough and this was not really needed. Having said that, it is nice to know that I can reach the quick connect on my motorcycle from just about anywhere in the garage and dont need to move the charger to different power outlets. It will also attach to the previously mentioned clamps as an extension, so if I want to clamp onto my 4x4 pickup truck battery I can easily reach it and connect to the charger so that I can place it and see the state of charging/reconditioning. Easily worth the nominal price for much added convenience.

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.

it makes it longer so you can plug it in more conveniently. exactly as you would expect. both ends water sealed just as the others so you can plug it in outside and trust it wont short out. i would argue 1 of these should come in the kit, but its all good still a great product
