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

This cable extension is a must have if you have a late model corvette and you want to be able to close the rear hatch completely. The cable that comes with the Ctek charger is to thick and causes the rear trunk on the corvette to pop up and I think long term storage on fiberglass that would be bad. The extension cord lies flat and you can actually slide it in the gap even with the rear hatch fully closed. Well worth the good price.

Product As expected. Could be a little longer since I have a big garage and got this to avoid using an extension cord.

Completely happy. Needed to charge Porsche in carport as not driven often as I am retired. Keeps the battery fully charged and ready to go.

Quality product

I was a little disappointed that the wire used is pretty stiff for the duty. Im a little concerned that flexing in service here will lead to premature failure. It hasnt failed yet (too early to tell). I was expecting the wire conductors to be the same more flexible materials used for the maintainers, and its definitely different. It may never be an issue, depending on how many disconnect, hang the cable, then reconnect cycles it has to endure in my service. Immediate product performance: The extension cable plugs into the maintainer connectors and the mating connector at the battery harness. It functions as advertised, allowing me to place the maintainer on the wall near and the wiring to more easily reach and connect to the car battery on the other side. *** This item is a regular purchase, outside the Amazon Vine review program. ***

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.

Works with both of my CTEK chargers and makes them more convenient to connect in the garage. The wire, however, is unusually stiff and almost awkward in this application. It is much stiffer that typical stranded copper or stranded copper-clad wire, almost like solid wire as it holds shape when bent or coiled.

As described

Got this to go with new Ctek for my NSX with connections under front hood. Easier to connect using this & keep Ctek up away from ground & car.

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.
