FAQs
Can these be used on small cars?
Yes, they are compatible with small cars, though they are specifically engineered for higher capacity demands.
Are the clamps insulated?
No, these are professional-grade un-insulated brass clamps, which require careful handling.
Will these work for a diesel engine?
Yes, the 35mm² core is specifically suited for the higher current draw required to crank large diesel engines.
How should I store these cables?
Store them in a cool, dry place and avoid tight kinks or sharp bends in the cable to protect the internal copper strands.
Are these suitable for 24V systems?
These cables are designed to handle the current of various systems, but always verify your specific vehicle's voltage requirements before connecting.
Troubleshooting
Vehicle still won't start after connection
Ensure the brass clamps are making direct metal-to-metal contact with the battery terminals and not grabbing onto plastic covers or heavily corroded surfaces.
Cables are getting hot during the attempt
Immediately disconnect the cables. This indicates a high resistance or a potential short circuit in the dead vehicle's starting system.
Pros and Cons
Pros
- Generous 4.5m length provides excellent flexibility in tight spaces
- Heavy-duty 35mm² cable core prevents voltage drops
- Solid brass clamps ensure a secure and conductive grip
- Suitable for high-demand engines like trucks and tractors
Cons
- Un-insulated clamps require extreme caution to avoid accidental shorts
- Larger cable diameter makes them bulkier to store than standard car cables
- No integrated surge protection mechanism
Setup, Compatibility & Care
To ensure longevity, always inspect the cable insulation for nicks or abrasions before each use. To connect, attach the red positive clamp to the positive terminal of the dead battery, then to the positive of the donor battery. Follow with the black negative clamp to the donor, and finally to a solid metal ground on the engine block of the dead vehicle. Keep the cables clean of oil and grease to prevent degradation of the casing. When finished, wipe the brass clamps with a dry cloth and store them coiled loosely to prevent internal wire breakage.
