Absolutely the best

I'm not sure about the other guy's quantity problem, but these are not only the best terminal protectors, in my shop I've found they are the ONLY terminal protectors that actually work. I just received another new jar from a local auto parts house (at a considerably higher price than Amazon), and while I'm not going to count them, the jar is full.

Don't waste your money on other brands, especially the ones that are red for positive and green for negative. This NOCO product with the thick oozy red material prevents all corrosion from forming on battery terminals. The battery tie-down bar will still corrode, but there will be NO corrosion on the actual terminals or cables.

Yes, I recommend this product.

Best Battery Accessory You Can Buy

My dad started using the washers 30+ years ago back when the packaging was a metal screw top and I've continued to put them on every battery we've worked on and I've never had a corrosion issue. I'm well into my 4 can of 50 so maybe 80+ batteries I've put them on. Marine, Farm, Lawn & Garden, Truck, Car, Top or Side post, Family, Neighbors, never seen one develop corrosion after they're installed. They last longer than the batteries do, I've reused them in a pinch without issue. These are not the red/green blister pack felt washers you see at the parts stores. They are a dark maroon color and they are impregnated with a greasy red colored chemical. Pair it with the NCP-2 spray on the terminal and the battery is totally protected against corrosion for the life of the battery.

Yes, I recommend this product.
