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

Works perfectly with charger as an extension cable.

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

Car charging

Perhaps a bit pricy but if you need to extend your CTEK charger this is what you need. As other reviewers mentioned it should come with a rubber cap on the connector but besides that its great.

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.

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.

Works as it should. The extra length allows more options to hook up the ctek.

Batteries die in the cold and rainy weather, my old charger had 3 foot leads and a 6 foot AC cord that required me to try to waterproof the cord and charger during use. This extension cable allows me to place the charger in the garage and charge the batteries while the cars are in the driveway. Perfect solution and addition to a great battery charger

Seems like this is very old stock. Item packaging was in good condition, but wire inside was very brittle and wire inside of the insulation made a cracking noisy while straightening it from the packaged wire-tied coil. For an item intended on carrying consistent current from a complex charging unit to an expensive automotive battery in a Porsche, this seems very cheap. When attempting to return, the only displayed option was bought wrong part which seems suspicious and not accurate. Not happy!

Why would CTEK allow the extension to be made from such low grade wire? This component demeans the CTEK line-for the sake of pennies. Imagine the behavior of cheap line in cold temps.
