Allstar Performance ALL76140 Red Battery Charger Post - Heavy Duty Car Battery Terminal Connector for Automotive, Marine & RV - Perfect for Jump Starting & Maintenance Charging

The quality is just as good as the positive reviews that I read before purchasing them. I was motivated to purchase these after I had to jump the engine battery on my boat. It was located in a difficult place to access with little room to work. After I saw these installed on my neighbor's boat, I absolutely had to have a set. To jump your battery, you simply pop the insulator caps off, attach your jumper cables, and you have an easy, instant, access point to jump-start your battery. You don't even have to get your hands dirty.Be sure to use a heavy gauge battery cable between the rear connection on these lugs and your battery post. Also be sure that nothing can touch and/or short between the rear connections on these lugs. The only thing that I would like to see changed on this product, are the threaded fastener rings that thread on the rear side, to hold the lug assembly in place. They used a typical, galvanized, conduit type nut that one sees inside electrical boxes. These would be better for boats if this threaded fastener ring, were made of stainless steel. One might want to spray paint that part for extra rust protection, before installation.Great Product
