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

This worked perfectly for our seldom used 2002 Mercury Mountaineer which is only driven on those rare occasions when we have our other car in the shop.

Great chord for my CTEK 3300 for a good extension to the battery maintainer. Well insulated against moisture as well.

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

Buy extension and you wont have to move bikes

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

The product is perfect for keeping the battery on my 599 fully charged. Anyone who knows; you don’t want a dead battery on a 599. Easy to attach clips to battery for temporary use. But for long term use the hard wiring is easy to attach to the battery using a wrench. Then just plug it in and leave it alone. Very easy disconnects allows for driving without accessing the battery. I also bought the 8’ extension for extra length around the exhausts and I have the unit wall mounted using the mounting holes on the unit. I have my other Ferrari’s on theses units as well. I highly recommend them for use with the high energy draining modern Ferrari’s. Plus, they extend battery life significantly.

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 extension is a great accessory for the CTEK battery charger I purchased. Make the reach from the charger to the car battery more versatile!

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!

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.
