Frequently Asked Questions
Can I use these cables for my diesel truck?
Yes. The 400 amp rating and 6 gauge construction handle the higher amperage draw of diesel cold starts. Make sure both vehicles have compatible battery terminals before connecting.
How do I store these to prevent corrosion?
Keep them dry and coiled loosely in a cool place. Copper wire resists rust, but store away from direct moisture. Periodically inspect the clamps and terminals for any buildup and wipe clean if needed.
Are 16 feet long enough for my setup?
Sixteen feet covers most vehicle-to-vehicle jump scenarios. If your engine bay is deep or you're jumping between vehicles parked far apart, measure the distance you need before relying on these. Longer cables give more flexibility.
