CTEKConnect Eyelet M6, Permanent Connection for Hard-to-Reach Batteries, Durable, Secure, Quick and Easy Connection for Your CTEK Battery Charger, for Cars, Motorcycles & Other Vehicles

Worked great to install in my lawn tractor so I can keep the battery charged when not used for periods of time.

Works great! Love my CTEK

I have enough cars, and now work remote enough that the cars sit and can run down the battery. These are really useful when you have a battery that’s squirreled away in the back of a car or under a bunch of panels. Using Alligator clips for that is a chore. I’m really happy I got one for each car that needed it.

This product is a fantastic find! It's reasonably priced, making it accessible for most budgets without compromising on quality. The product is exactly as described, and its usefulness cannot be overstated. I've found it to be incredibly practical and efficient in meeting my needs. The attention to detail is impressive, and the performance is on par with more expensive alternatives. If you're looking for something reliable, well-made, and at a fair price point, this is the perfect choice. Highly recommended!

I think it will work for my side posts as well but not installed yet.

The M6 eyelet fit the 6mm stud on the negative post clamp that is used to tighten the battery cable to the terminal. It did not fit on the positive side for two reasons. First, the 6mm nut on the positive clamp is rounded on the bottom of the nut (so that it tightens the clamp. Second, if the horizontal bar is pulled off and the eyelet is placed under the bar then the bar wont lay flat because the insulated part of the eyelet is in the way. I worked around that by using an M8 eyelet instead, but it was still quite tight. There is a larger stud (m10 or m12?) on the positive clamp, further back, that might have been a better option, but I don't recall seeing a similar size stud on the negative.I have these connectors installed on all three of my vehicles and they are very convenient. Much nicer than using the alligator type clamps that come with the smart charger. The older connectors came with the inline fuse, but my recent purchase did not.

High-end car manufacturers sell these to their buyers. That says it all! Quality you can trust on!

Be sure not to over tighten the terminal ends it’s soft plated copper.
