20 FT 4 Gauge 500 AMP Booster Cable Set
Heavy-duty booster cables rated for 500 amps and built to handle serious jump-starting demands. The 4 gauge copper wire delivers maximum current flow with minimal voltage drop, while the 20-foot length gives you reach in tight engine bays or dual-battery setups. Insulated clamps grip terminals securely without slipping mid-jump.
Key Features
- 4 Gauge Copper Wire - Lower resistance means faster current delivery and less heat buildup during extended cranking.
- Insulated Clamps - Rubberized grip prevents accidental terminal contact and protects battery posts from corrosion during connection.

Frequently Asked Questions
Will these cables work with my truck's dual-battery setup?
Yes. The 20-foot length and 500-amp rating make them ideal for vehicles with batteries spread across the engine bay or mounted remotely. Test your actual run length before your first jump to confirm clearance from hot engine surfaces.
Do I need to do anything to the clamps before using them?
Just inspect them for corrosion or debris before connecting. If your battery terminals are heavily corroded, clean them off first — this improves contact and reduces resistance during the jump.
Can these handle repeated use without wearing out?
Copper wire and quality clamps hold up well across multiple jump cycles. Store them coiled loosely in a dry space to avoid kinks that can crack the insulation. Check clamps for tightness every season.
