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

The cables that are connected to my CTEK battery maintainer were long enough to reach from a power outlet to the car, but the CTEK ended up on the floor of the garage. This cable enabled me to get the charger off the floor where it wont get stepped on etc. The quality of the connections is very good. Nice cable.

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.

Adds additional length and flexibility the charging unit. Quick connect and release...just squeeze and push together or pull apart.

Worked great to extend the charging connector on my motorcycle. The battery on my BMW R1200CL is under the gas tank and this extension makes it very easy to hook up the charger.

The connectors work well, just wish it would have had the specs in the listing. It is only 16AWG and can support 10A Max. I was planning on splicing it into my 12AWG, 50A system, but cant now.

Once the extension cable was connected to the CTEK eyelet or CTEK clamp it did not work. I purchased two different extension cables and both were inoperable. Unfortunately, l had to return both extension cables. When I connected CTEK charger directly to eyelet or clamps NO issues.

The idea is great if the cable would keep working. It failed after minor use since purchased December 9 2020. I dont see anyway to get a replacement on my order page. Im not asking for a refund, Im asking for a warranty replacement for this extension cable. It will not work when used. The CTEK MXS 5.0 works fine when not connected to the extension cable otherwise it goes into a flashing green light which indicates no connection to the battery. Bad Extension Cable . I would give CTEK a good review if they would warranty their product but I see any way here on Amazon to get this cable replaced. Its only $12.00 but it should work longer than 2 months. Ben UPDATE CHANGED FROM 1 STAR TO 3: I added some CRC Technician Grade Dielectric Grease to the ends of the cable connections. It has been working fine now. Could it be that simple? Yes it could. I have used the CRC product many times on electronic connections with great success. Time will tell. Still a little disappointed that the cable failed in the first place. They need to review the end connectors and if necessary note the need for a dielectric grease if the cable fails. Back to one star. I know it has been a while but I really dont use this extension much. Over the past several months this product has been working on and off. It seems to have some sort of short or the connectors are becoming defective. I cant say this product is good.

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.

Not too much to say here other than if you need an extension cable for your CTEK battery tender this will do the trick. If you appreciate the quality of the CTEK battery tender you will likewise be happy with the cable. I works wonderfully for us.

Wanted to get the wiring for my CTEK 3300 cleaned up and reclaim a 50 heavy duty extension cord Id been using on the AC side of the battery maintainer, so I pulled the trigger on this Comfort Connect (aka 12V/cigarette lighter) extension cable. As always, it arrived in two days thanks to Prime. What can I say? Its an extension cable and it works like a champ. If youre currently using the Comfort Connect adapter for your CTEK maintainer and need an extension cable, this is the item for you.
