SUNMORN Battery Terminal Connectors, 0/2/4/6/8/10 AWG, Zinc Alloy

If you are running a high-demand electrical setup with multiple accessories, standard factory battery terminals simply cannot handle the load. These SUNMORN battery terminal connectors are an outstanding upgrade. Not only do they look incredibly sharp and professional under the hood, but they also offer an exceptional range of gauge options, making it a breeze to cleanly connect multiple power inputs directly to your battery.Key HighlightsMassive Multi-Input Capability: With dedicated ports that accept 0, 2, 4, 6, 8, and 10 AWG wire, these terminals allow you to run heavy-gauge amplifier lines, winch power, or secondary charging circuits without a messy stack of ring terminals.Premium Styling: They look great once installed. The clean, machined finish adds a high-end, custom look to the engine bay that instantly replaces ugly, corroded factory hardware.Rock-Solid Clamping: The set screws lock down tightly on the wire conductors, ensuring a highly secure, low-resistance connection that won't vibrate loose over time.Clear Identification: They are clearly marked for positive and negative posts, ensuring a safe, straightforward installation process.Performance & InstallationInstallation is incredibly clean. Instead of crimping multiple large ring terminals together onto a single post, you simply strip your power cables, insert them directly into the correctly sized terminal ports, and torque down the hex screws.The terminal clamp itself grabs the battery post firmly with even pressure, ensuring excellent conductivity for clean power delivery. The versatility of having so many different gauge sizes in one block makes organizing your auxiliary wiring layout simple and professional.

Guilty. I read reviews and still took a chance. But, it was my error. See, these terminal connectors are two sizes and they are labeled (+) and (-). I didn’t realize and I broke one, just like others commented, trying to spread it open to fit it on the terminal. The positive is slightly larger in diameter than the negative. Glad it came with 4 because once I realized, I was fortunate to have two more to correct my incompetence. Once you put the correctly labeled connector on the correct terminal, they fit just fine. Even come with terminal shims to shore up any play or looseness. I’d recommend not trying to spread them open for more room to fit. Just put the correct ones on the correct terminal. Quality is good. Wire connections are really good. They look good and they work. No issues with conductivity. I paired these with upgraded 2 AWG battery cables. Handled it everything.

Great product. Fit my wiring needs and cleaned up the ugly factory connectors

These are great replacement terminals, however make sure you trim the battery cable to size to fit in it snuggly or it could come loose, once you figure it out, they work great, the plastic cover that comes with it, is kinda hard to take off though.

Looks nice but doesn't fit all batteries

I have these on several vehicles, and my boat. The multiple connection points work great for adding electrical accessories and aftermarket car audio components. they've also came in handy to replace bad OEM pre-made terminals, popular on so many vehicles these days, that have enough wire to cut off the old terminal and install these in their place. For marine use, plan on replacing every two years if in freshwater, or once a year in a saltwater application. But they're cheap enough that replacing them is just a drop in the bucket compared to what we spend on our boats. For automotive, they'll last a little longer, but they will start corroding after a couple of years. A little terminal protectant makes them last longer.

Excellent quality and price

Heavy stainless design, needs both Allen and Open End Wrench to install/ remove. Bolt is not captured and will rotate w/ nut. Don't use the plastic protectors- once on, they don't come off by hand. Even with a screw driver they're a pain in the a$$. I suspect they would be a hindrance if you needed a jump on the road in the dark.

Fancy looks nice works ok but i would prefer to get a real tough one

Las terminales están construidas con materiales de excelente calidad, es pesada pero cómoda de poner en la batería, los cables se mantienen fijos y son fáciles de instalar, como extra cuenta con telas antisulfatantes, anillos de metal para terminales muy delgadas y tapas para evitar polvo y agua.

Used them no problem

Easie to install. Keeps post clean and dry

Excelentes terminales, orden y limpieza en los bornes de mi batería. Producto de alta calidad.
