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

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

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

Quality product

Easy hook up to permanent battery contact. Just snap in place at both ends.

A nice extension for connecting from the charger to the battery. This allows the charger to placed outside the engine and even away from the vehicle being charged. It is designed to be used with other CTEK Components keeping the + and - leads connected correctly.

Satisfied

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.

This CTEK extension allows me to connect the alligator clips to my battery while having the battery charger inside near the outlet. Very handy in the winter when I need to top off a infrequently driven vehicle while not leaving the garage door open. The wiring is not too thick (which can be good or bad depending on how you look at it) and doesnt appear to effect the current coming from the charger. Although, when using the extension, I have noticed the voltage drops to 14.12 instead of the advertised 14.4 in the owners manual during stage 3.

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

Worked great for storage of car during winter. No need to keep hood up anymore when charging. Able to keep car cover on all the time during winter.
