Protect your car's battery the easy way with these simple rubber terminal covers! This 4-pack includes red and black caps so you can easily tell positive from negative. They're made from flame-retardant rubber that insulates up to 2000V and handles temps from -70°C to 105°C—pretty tough stuff. Just pop them onto your battery's top posts after connecting the cables. They'll shield the terminals from dust, moisture, and accidental shorts, which can extend your battery's life and prevent corrosion. The inner diameter is about 0.6 inches, and they fit most standard car, motorcycle, truck, RV, boat, and tractor batteries. But please, check your terminal size and shape before buying to make sure they'll fit! Installation is literally plug-and-play: no tools, no skills needed. Whether you're a DIY car owner or a pro mechanic, these caps are a smart, affordable way to add a layer of safety under the hood. Keep your battery clean, safe, and clearly marked. Driving with peace of mind starts with the small details—grab a set today!
