Frequently Asked Questions

What is included in the set?
Each set includes two (2) premium 24-inch 4 AWG battery cables: one red (positive) and one black (negative). Both cables are professionally assembled in the USA and come with pre-installed heavy-duty tinned copper ring terminals.
The cables feature high-grade EPDM (Ethylene Propylene Diene Monomer) rubber insulation. This material is preferred for its extreme flexibility—making it easy to route through tight spaces—and its resistance to heat, oil, abrasion, and chemicals.
Yes. The cables use tinned copper lugs and are sealed with adhesive-lined clear heat shrink tubing. This creates a moisture-proof and airtight seal that protects the connection from corrosion, which is essential for marine, boat, and outdoor environments.
How flexible are these wires?
Because they are made with a high strand count of fine copper, these cables are significantly more flexible than standard industrial wire. They can easily be bent and routed around engine components or inside battery boxes without kinking.
The cables are rated for DC systems up to 1000V, making them safe for a wide variety of high-voltage DC applications.
Yes, the DFNA True® 4 AWG Battery Cables include a 1-year warranty against defects in materials and craftsmanship.
