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

Great product. Makes it much easier to charge the battery in my car. I no longer have to worry about parking my car close enough to an electrical outlet for the charging cords to reach my car!

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

A must have for any CTECK user! This is on my 68 GTO and I have it wired so the comfort connector stays on the battery terminals and comes out of the grill. All you need to do is route it away safely down and through the front grill. I have it secured in such a way I can easily disconnect my car from the wall charger unit and tuck the comfort connector away until I pull the car back in the garage. My only gripe is that this unit didn’t come with a rubber end cap. Easy fix though because I took the one off the wall charger unit. The car is going to see more of the elements than the charger in my garage so it only makes sense that the comfort connector would be capped off. All in all, one of the best investments for any classic car owner/collector. Thanks Jay(Leno) for putting me on to CTEK!

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.

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

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

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

This extension enables me to charge my battery and safely run the cord away from foot traffic.

I own 2 of these cables. Neither one works right. I have a CTEK MXS 5.0 charger that I use to maintain my 2 AGM car batteries. In fact, I like the charger so much I bought a second one. I dont know if its the connectors or the cable itself, but when its used with this charger, the charger will get stuck in DESULFATION mode at the beginning of the program and take nearly forever to progress, if at all. Maybe theres some resistance or a bad connector faking out the chargers voltage sensing, but I just cant use this cable with it. Ive tried snugging up the connectors and using an anti-ox compound to help with resistance, but no luck. I dont recommend anyone purchase this item if you use a CTEK MXS 5.0 at least. I just hook it up straight to the comfort pigtails that are installed on both my auto batteries with no issues, so theres something wrong with this particular extension cable.

I like these comfort connects over the old school sae connector. When I swapped to my lithium battery I wanted it to be obvious so I remember not to use my old battery tenders with my lithium battery so this is perfect. This extension could be longer but it will do I suppose.
