Extended Product Information
FAQs
Are these cables suitable for a 3.0-liter engine?
No, these leads are rated for engines up to 2500CC. Using them on larger engines may cause the cables to overheat.
Do I need to leave the donor car running?
Generally, it is safer to keep the donor engine off while making the initial connections to prevent electrical surges, though some procedures suggest running it briefly before attempting to start the dead vehicle.
How do I identify the positive and negative terminals?
Positive terminals are typically marked with a '+' sign and often have a red cover, while negative terminals are marked with a '-' sign.
Can these be used on electric vehicles?
No, jumping electric vehicles or hybrids is generally not supported by standard lead sets and can damage the vehicle's electrical systems.
How should I clean the clamps if they get dirty?
Wipe them down with a dry, clean cloth after use. Avoid using water or harsh solvents directly on the cable insulation.
Troubleshooting
Vehicle still won't start after connection
Ensure all four clamps have a firm, direct metal-to-metal connection on the battery terminals and that the recipient vehicle's grounding point is free of paint or grime.
Clamps are getting very hot
Immediately disconnect the leads as the engine size may exceed the 400AMP rating, or there may be a severe short-circuit in the recipient vehicle's battery system.
Pros and Cons
Pros
- Resistant to common automotive fluids like oil and acid
- Easy to store with the included zip-up bag
- Fully insulated clamps improve operator safety
- Anti-tangle cable design simplifies the connection process
Cons

Setup, Compatibility & Care
To ensure the longevity of your cables, always clean the metal clamps after use to remove any potential corrosion or battery acid residue. Store the leads in the provided zip-up bag in a dry environment to prevent moisture buildup on the terminals. Before each use, inspect the cable insulation for any nicks or cuts. These leads are compatible with most standard passenger vehicles up to 2500CC; however, avoid using them on larger commercial vehicles or heavy-duty machinery as the 400AMP rating may be insufficient, potentially causing the leads to heat up dangerously.
