Jumper Cables

Heavy-gauge cables to jump-start a dead battery from another vehicle

Jumper cables let you start a car with a dead battery using power from another running vehicle. The two things that matter most are wire gauge and length: a lower gauge number means thicker wire that carries more current, while longer cables give you flexibility when cars cannot park nose to nose. Solid clamps that grip the terminals firmly round out a dependable set.

For larger engines, heavier gauge cables deliver a more reliable jump, so consider your vehicle size when choosing. We curate top-rated picks on Amazon so you can compare gauge, length, and clamp quality. Keep a set in your trunk and learn the correct connection order, since hooking them up safely protects both vehicles.

FAQ

What gauge jumper cables do I need?
Lower gauge numbers mean thicker wire and more current capacity. Larger engines and SUVs benefit from heavier gauge cables, while smaller cars can use lighter ones.
How long should jumper cables be?
Longer cables make it easier to reach between vehicles that cannot park close together. Keep in mind that very long cables can lose some efficiency.
What is the correct order to connect them?
A common method is connecting positive to both batteries, then negative on the good battery, and the final negative to an unpainted metal ground on the dead car. Always follow both vehicles' manuals.
