50 mm² Heavy Duty Booster Cables – LG1900

The LG1900 50 mm² heavy duty booster cables are built for hard starts and large engines. Four metres long, with strong wide-jaw clamps and thick copper-clad aluminium conductors, they deliver the cranking current needed to jump-start large commercial engines, including V8 HGV tractors such as the Scania 770S.

The cables are aimed at professional users – recovery operators, commercial fleets, plant hire and agricultural contractors – where engines are large, batteries are remote and access is awkward.

Heavy Cranking Current for Large Engines

The 50 mm² copper-clad aluminium (CCA) conductors carry high cranking current along the full 4 m length, with low voltage drop. This allows reliable jump starts on HGV, plant and agricultural engines where light-duty leads would overheat or fail to deliver enough current.

Strong Wide-Jaw Clamps

The clamps are designed to bite cleanly onto commercial battery posts and chassis earth points, giving a stable mechanical connection that holds when the engine cranks. Red and black sleeving keeps polarity clear in poor light or bad weather.

4 m Length for Awkward Vehicles

The 4-metre reach allows vehicles to be positioned safely when nose-to-nose access isn't possible, which is common with trucks, buses, tractors and machinery. A zip carrier bag is included to keep the cables tidy in the cab, workshop or service van.

Built for Professional Use

The cables use a thick, flexible outer sheath designed to handle regular handling, dragging and coiling in commercial environments. The build is specified for workshops, recovery trucks and fleet maintenance rather than hobby or occasional DIY use.

Key Features

• 50 mm² copper-clad aluminium (CCA) conductors.
• 4 metre cable length.
• Red and black polarity identification.
• Heavy duty wide-jaw clamps for commercial battery posts.
• Proven to jump-start V8 Scania 770S class engines.
• Zip carrier bag included for tidy storage.
• Thick, flexible outer insulation for daily commercial use.
• Designed for professional workshop, recovery and fleet use.

Ideal Applications

• HGV and articulated trucks including large V8 tractors.
• Bus and coach fleets on depot and roadside call-outs.
• Agricultural tractors, combines and telehandlers.
• Construction and plant including excavators, dumpers and loaders.
• Recovery operators and mobile mechanics.

Important Safety Note

Always follow correct jump-starting procedure: connect positive to positive first, then negative to a clean earth point on the receiving vehicle's chassis. Avoid sparking near battery vents. For best results, use by a competent vehicle electrician or trained operator.
