Product Information
Full details
These St Helens Heavy Duty Battery Jump Leads are designed for vehicle owners needing a reliable way to start a car with a dead battery. Their key benefit is robust construction with powerful spring jaw clips and heavy insulation for safe, efficient power transfer. A potential caveat is the maximum power rating of 50A, which may not be sufficient for all heavy-duty vehicles.

FAQs
What is the maximum amperage these jump leads can handle?
These St Helens jump leads have a maximum power rating of 50A.
What length are the jump leads?
The jump leads are 2 meters in length.
Are these jump leads suitable for diesel engines?
While they can be used on some smaller diesel engines, their 50A rating may be insufficient for larger diesel engines that require a higher cranking amperage. Always check your vehicle's manual.
How do I ensure I connect the leads correctly?
Always connect the red (+) lead to the positive (+) terminals and the black (-) lead to the negative (-) terminals. For the final connection of the black lead, attach it to an unpainted metal surface on the chassis or engine block of the dead car, away from the battery.
Can I use these jump leads to charge a battery?
No, these jump leads are designed solely for jump-starting a vehicle with a dead battery, not for charging it.
What should I do if the battery terminals are corroded?
Gently clean the battery terminals with a wire brush or a dedicated terminal cleaner before attaching the jump leads to ensure a good electrical connection.
How should I store the jump leads when not in use?
It is recommended to store the jump leads neatly coiled, preferably in their original packaging or a protective bag, in a dry place away from direct sunlight and extreme temperatures to preserve the insulation and clips.
Troubleshooting
Vehicle still won't start after connecting jump leads.
Ensure the clamps have a firm connection on both batteries. Check that the donor vehicle's engine is running. Verify the polarity connections are correct. The battery in the dead vehicle may be beyond jump-starting or there might be another issue with the vehicle's starting system.
Sparks when connecting the final black clamp.
This is often normal due to completing the circuit. However, ensure the final black clamp is connected to a solid, unpainted metal surface away from the battery to minimize the risk of igniting hydrogen gas. If sparks are excessive, check clamp connections and ensure they are not touching each other.
Jump leads feel hot during use.
This can occur if the vehicle requires a sustained high current for starting. Ensure the clamps are making good contact. If the leads become excessively hot, disconnect them immediately and allow them to cool. The vehicle's starting system may be drawing more power than the leads are rated for, or the battery may be failing.
Clips are difficult to attach securely.
Ensure the battery terminals are clean and free from corrosion. Wipe away any dirt or debris that might be preventing a good fit. Apply firm pressure when attaching the clips to ensure they grip the terminals effectively.
Pros and Cons
Pros
- Secure and strong grip from crocodile clips.
- Easy to identify correct polarity with color-coding.
- Enhanced user safety due to heavy insulation.
- Sufficient length for convenient connection between vehicles.
- Durable build for reliable performance.
Cons
- Maximum power rating of 50A may be insufficient for some heavy-duty trucks or large engines.
- The cable thickness, while insulated, might be less flexible in very cold temperatures.
- Requires careful handling to avoid damaging the insulation or clips.
- Not suitable for charging batteries, only for jump-starting.
Setup, Compatibility & Care
Setup:
- Ensure both vehicles are turned off and parked close enough for the leads to reach.
- Connect the red positive (+) clamp of the jump lead to the positive (+) terminal of the dead battery.
- Connect the other red positive (+) clamp to the positive (+) terminal of the donor battery.
- Connect the black negative (-) clamp of the jump lead to the negative (-) terminal of the donor battery.
- Connect the final black negative (-) clamp to an unpainted metal surface on the engine block or chassis of the dead vehicle, away from the battery (this is a safety precaution to prevent sparks near the battery).
- Start the donor vehicle and let it run for a few minutes.
- Attempt to start the dead vehicle.
- Once the dead vehicle has started, carefully remove the leads in the reverse order: black from the chassis, black from the donor battery, red from the donor battery, and red from the formerly dead battery.
Compatibility:
These jump leads are suitable for most standard 12V passenger vehicles and light commercial vehicles with a maximum power requirement up to 50A. They are not recommended for heavy-duty trucks, industrial machinery, or vehicles requiring higher amperage for starting.
Care:
- After each use, wipe the clamps and cables clean with a dry cloth.
- Store the leads in their original packaging or a designated bag to protect the insulation and clips.
- Inspect the cables and clamps for any signs of damage, wear, or corrosion before each use. Do not use if damaged.
- Keep the leads away from excessive heat, sharp objects, and corrosive substances.
