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

Works as expected. One thing with high amp products, it might spark sending be surprised. I was in my dry garage during the rain when plugged it in and there was a small spark and noise but I was expecting this. I wish there was a ground on the wall side but understand they attempted to make this country agnostic and wide support.

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.

It allows me to charge the battery in the engine compartment with the hood closed and the charger outside of the engine compartment to better dissipate heat from the body of the charger

Worked perfect

Easy hookup & just the right length in my garage. Purchased with 12 v adapter & CTEK charger.

Works perfectly with charger as an extension cable.

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.

I recommend this extension. Your power outlet may not always be as close and you may not have a power extension box. Due to the length of the cable that attached to the tender, this makes it easier to run your cabling from you hood such that you close the hood while the battery is being charged.

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

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.
