High-quality battery pole terminals designed for reliable 12V connections Key benefits Durable, low-loss conductivity: Solid brass contacts provide stable, conductive connections that reduce power transmission losses and help maintain reliable starting and accessory power. Long service life: Brass contacts and a thick ABS housing resist rust and corrosion, improving durability in regular use and harsh environments. Fast, simple attachment: Clip-on cap design allows quick installation and removal for faster battery maintenance or accessory changes. What it does and why you need it Replaces worn or corroded battery terminals to restore a secure electrical connection and reduce voltage drop. Provides a compact, insulated connection point for 12V batteries used in vehicles and portable equipment. Helps prevent flaky starts, dimming lights, and accessory malfunctions caused by poor terminals. Compatibility and dimensions Designed for standard round battery posts on 12V batteries. Positive terminal diameter: approx. 18.0 mm (0.7 inches). Negative terminal diameter: approx. 18.3 mm (0.72 inches). Maximum cable size accommodated: 6 mm (0.24 inches). Overall product size: approx. 6.8 x 4.8 x 2.5 cm (2.68 x 1.89 x 0.98 inches). Suitable applications Cars and trucks: Replace corroded terminals to improve starting reliability and restore accessory power. Recreational vehicles and boats: Securely connect batteries in caravans, motorhomes, and boats for dependable power to lighting, pumps, and appliances. Powersports and small equipment: Use on ATVs, motorcycles, and other vehicles or electrical devices that use standard round 12V battery posts. Installation notes Clip-on design attaches to the battery post by clamping the cap and lifts off for removal, enabling faster maintenance and swaps. Check cable size (maximum 6 mm / 0.24 inches) and post diameter before fitting. Materials and performance Brass contacts for conductivity and corrosion resistance. Thick ABS housing for mechanical stability and insulation. Designed to reduce power transmission loss and provide a longer functional life compared with corroded OEM terminals.
