12AWG Heavy Duty Battery Power Cord 2-Pair M3–M10 O Terminal
Upgrade your vehicle, RV, camper, or marine electrical system with the Quake 12AWG Heavy Duty Battery Power Cord — a 2-pair set engineered for robust, long-lasting power connections. Featuring universal M3–M10 O-ring terminals and a high-purity copper core, this wire delivers stable, high-current transmission for 12V and 24V systems with minimal voltage drop and maximum conductivity.
Made in Mainland China.
Core Features
Superior Corrosion & Oxidation Resistance
The outer insulating sheath and O-ring terminals both feature upgraded anti-corrosion treatment. The thickened sheath resists oil, water, high temperatures, and aging, while precision electroplated metal terminals guard against rust and oxidation. Designed to thrive in engine compartments, humid outdoor settings, and marine environments, this cord maintains stable electrical performance year-round and significantly extends service life.
Standard 12AWG Thick Gauge — Stable High-Current Transmission
Built with a pure high-conductivity copper core at a standard 12AWG gauge, this cable features ultra-low resistance and fast current conduction. Unlike thin, undersized wires, it supports continuous high-current operation without overheating or voltage drop — reducing power loss and ensuring steady output for all your vehicle electrical equipment.
M3–M10 Universal O-Ring Terminal — Wide Compatibility
Precision-machined O-ring terminals cover M3, M4, M5, M6, M8, and M10 screw hole specifications. They fit snugly with battery poles, inverter interfaces, solar system wiring studs, and automotive electrical connectors. The integrated crimping process ensures a firm, rattle-free connection with no wire pullout or loose contact — compatible with the vast majority of vehicle power accessories on the market.
Heavy-Duty & Safety-Optimized Construction
The flexible yet tough wire body resists pulling, bending, and abrasion — ideal for complex vehicle installation layouts. A high-insulation, flame-retardant outer layer effectively isolates current and guards against leakage and short circuits, fully meeting automotive electrical safety standards to keep your vehicle circuit system protected at all times.
2-Pair Value Set — Quick Plug-and-Play Installation
Each package includes 2 complete pairs of battery power cords, covering both positive and negative pole connections in one purchase. The pre-crimped, integrated-molding design requires no additional crimping tools or welding. The flexible wire body is easy to route and trim, allowing fast, hassle-free installation that saves time during modification or maintenance.
Wide Application Scenarios

Frequently Asked Questions
Q: What terminal sizes are compatible with this 12AWG battery power cord?
A: The Quake 12AWG battery power cord comes pre-fitted with universal O-ring terminals that are compatible with M3, M4, M5, M6, M8, and M10 screw hole specifications. This broad range makes it suitable for most vehicle battery posts, power inverter studs, solar wiring terminals, and automotive electrical connectors without any modification.
Q: Is this battery cable suitable for both 12V and 24V systems?
A: Yes. This heavy-duty battery power cord is rated for universal 12V and 24V low-voltage DC systems, making it compatible with a wide variety of vehicles and setups including cars, RVs, campers, trailers, marine vessels, ATVs, UTVs, and solar battery banks or power inverters.
Q: Does installation require any special crimping tools or soldering?
A: No special tools are needed. The cords feature a pre-crimped, integrated-molding design — the terminals are already professionally crimped onto the wire, so installation is a straightforward plug-and-play process. Simply connect the terminals to the appropriate studs or posts and secure with the matching bolt size.
Q: How does the corrosion-resistant coating hold up in outdoor and marine environments?
A: Both the insulating sheath and the metal O-ring terminals feature upgraded anti-corrosion treatment. The sheath resists oil, moisture, UV, and high temperatures, while the electroplated terminals resist rust and oxidation even in humid marine or engine-bay conditions. This ensures stable electrical contact and a long service life regardless of the operating environment.
