Full details
The Ring Automotive RBC250A jump leads are designed for car owners and roadside emergency kits, offering a reliable solution for jump-starting petrol and diesel engines up to 5.5L. With their generous 3.5-meter reach and heavy-duty 25mm cross-section, these cables provide the durability needed for frequent use, though their robust construction means they take up more storage space than lightweight alternatives.

FAQs
Can I use these cables on a 5.5L engine?
Yes, these jump leads are specifically rated for engine sizes up to 5.5L.
Are these cables safe for modern cars with sensitive electronics?
Yes, as long as you follow the correct connection sequence, they are suitable for standard 12V vehicle systems.
Why is the cable length important?
The 3.5m length allows you to connect batteries even when vehicles are parked nose-to-tail or at awkward angles.
Do I need to leave the donor vehicle running?
It is recommended to have the donor vehicle running to provide a stable charge to the depleted battery.
How should I store these cables?
Coil them loosely and store them in the included nylon bag in a dry area of your vehicle.
Troubleshooting
Engine still will not start after connecting
Ensure the clamps have a solid metal-to-metal connection on the terminals and that the donor vehicle engine is running.
Cables are stiff in cold weather
While the PVC coating is designed for flexibility, bring the cables inside to warm up if they have been stored in freezing conditions for an extended period.

Setup, Compatibility & Care
To use these cables, ensure both vehicle ignitions are off before connecting. Connect the red positive (+) clamp to the positive terminal of the dead battery, then the other red clamp to the positive terminal of the donor battery. Connect the black negative (-) clamp to the negative terminal of the donor battery, and the final black clamp to a grounded metal part on the dead vehicle's engine block, away from the battery. When finished, disconnect in the exact reverse order. Keep the cables clean by wiping the clamps after use, and store them in the provided nylon bag to prevent moisture build-up.
