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

The cables that are connected to my CTEK battery maintainer were long enough to reach from a power outlet to the car, but the CTEK ended up on the floor of the garage. This cable enabled me to get the charger off the floor where it wont get stepped on etc. The quality of the connections is very good. Nice cable.

***See update at end*** I have my CTEK battery tender on a shelf and use this extension to reach into my car, via a CTEK cigarette lighter adapter. About every other day I find the lights blinking indicating a poor connection. I have tracked down the problem to the coupling between the main unit and this cable. The clips fasten tightly, everything is clean and firm, yet when the fault occurs the slightest touch will restore connection, only to fail again sometime later. Its unknown what causes it to break connection as this runs through a completely undisturbed location in a very clean garage. The convenience of the extra length is great, but the reason for being is to maintain a battery and its not doing its job. Relying on this to keep your battery topped up will result in disappointment if its prone to random failure such as this. I cannot recommend it. UPDATE: I unclipped the Comfort Connect cable and very carefully applied a conductive paste (Ox-Gard) with a toothpick inside each of the two barrels of the female side of the connector, then reconnected. This has solved the problem and the connection is now stable, device working properly. Sloppy build quality but easy fix.

Buy extension and you wont have to move bikes

The plug fits perfectly into the existing CTEK charging cable as expected. Not much more to add. If you need additional length in your charging cord, then this is the extension cable to buy.

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

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

Works great. Clicks nicely and securely. It extends the battery connection to outside the trunk space so the charger can be more conveniently located. The cable did not affect how the charger senses the voltage or charges the battery. I highly recommend this product.

Very helpful due to the layout of the power outlets in my garage. Excellent.

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.

Ctek battery maintainers are a must have if you store a summer ride. The extension plug allows flexibility in where you place the unit. Most people that I know that use one do not want to store the unit on the car in case it were to malfunction and heat up. The extension cord is built with the same standard for quality.
