I replaced both of my Optima YELLOWTOP batteries in my Chevy/Duramax 3500 Crew Cab the other day (diesel engines require dual starting batteries) and realized that I was badly needing a clean up of my 12v wiring under the hood. I have added many accessories over the years, including an onboard air compressor for my Grover air horn, a new stereo system with a high output amplifier, front and rear cameras, HID headlights, a 1200 piece starlight headliner, etc., etc., etc. You get the idea. 🤣 I found these battery terminals while searching for a solution to the obscene cluster of wiring that was attached to my old battery terminals, as well as to multiple grounding points throughout the engine bay. I compared the design, build quality and customer reviews of many different types of terminals before deciding upon these. These puppies are very well made! Solid aluminum blocks with multiple attachment points for a variety of wire gauges. And, they have well designed terminal clamps that you can actually securely tighten without fear of them snapping in two when applying enough torque to make a tight, complete contact connection with the battery posts. About an hour’s worth of work, some heat-shrink tubing and some quality ring connectors, a few (actually, quite a few) nylon tie-wraps and a roll of wire looming tape and my engine bay is looking (and actually working) MUCH, MUCH better!!! 😄 I’ve noticed that my stereo system is actually sounding considerably better than when I was using a chassis ground connection instead of a terminal ground connection. Furthermore, I’m no longer ashamed to open my truck’s hood! 😂 Although these are slightly more expensive than some of the other brands out there that offer similarly designed products, I honestly believe these are far and away superior. They’re honestly worth every single penny, and then some!!! 😉 I highly, highly recommend these battery terminals! Your engine bay, your battery and even your electronic accessories will ALL thank you!!! 😀 Read more

Picked these you to replace my worn out KnuConcepts terminals. 2015 Tacoma w/ 27F battery. Plenty of room in all directions for mounting orientation. Very functional and easy to use in comparison to my old terminals. The listing pictures don't quite do these justice. There is a nice pocket machined on the back around the clamp to accommodate battery posts that may have a lip or shoulder. As well on the back side of the screw block there is a piece of thick plastic attached to mitigate the blocks from shorting out on any metal that may be below them. Lastly there is a bag of star type locking washers for the side screws. The hardware is metric, nuts were 13mm and the hex cap screws are a 5mm Allen. The terminal clamps fit perfectly and are extremely easy to remove and reposition if needed. All in all these are a great value for the money, even compared to the slightly cheaper SHCA blocks.

Working great so far. The only issue I had was I could not find terminal covers to fit these anywhere. Finally came across The Artisan Garage (Lumberjack Engineering) and Alex custom designed a 3D printed set for me. Highly recommend them, they are high quality and fit perfectly, with cutout slots for customizing your wiring setup. Now I don’t have to worry about a short-circuit. Read more

Looks great. Damages and scratches easily. Expected in a engine bay. Excellent quality, worked for my setup. Terminals could be spaced a bit more, wide terminal ends might overlap. Slipped off easily with tapered end at first. Secure and press down tightly, it fit. Overall expensive price but worked as expected. Read more

I purchase hundreds of items per year on amazon . I never leave a review. I made an exception for this product. This is truly the best battery terminal that has ever been made. Well machined single piece of aluminum and you can attach a variety of guages of wire in multiple ways. Truly ingenius producg Read more

This is an excellent battery connector. It has lots of options, and is remarkably well made. It has lots of options for attaching different gauge cables, and locks everything down nice and tight. You'll need a couple different hex wrenches to tighten everything up. Read more
