Draper Retractable Booster Cables, 3.5m x 29mm²

Never be stranded with a flat battery again — the Draper BCS11 retractable booster cables deliver professional-grade jump-starting performance in a compact, organised package. Combining heavy-duty cables with smart diagnostic technology, the BCS11 is a must-have for any vehicle toolkit, garage, or glove box emergency kit.

Smart LCD Display for Instant Diagnostics Unlike standard jump leads, the BCS11 features a built-in LCD display that shows real-time battery voltage and alternator charge rate — giving you valuable insight into your vehicle's electrical health before and after a jump start. Know instantly whether your battery is holding charge or your alternator needs attention.

8 Illuminating LEDs for Low-Light Use Breakdowns don't always happen in daylight. The eight integrated illuminating LEDs light up the engine bay so you can connect and disconnect cables safely, even in poor visibility — whether that's a dark car park, a country road at night, or an underground garage.

Heavy-Duty 29mm² Retractable Cables The 3.5-metre PVC-insulated cables are wound onto a built-in retractable reel with a winding handle, keeping them tangle-free and ready to deploy at a moment's notice. At 29mm² cross-section, the cables deliver the high current capacity needed for reliable engine starting, while the heavy-duty handles with PVC covers ensure a secure, safe connection every time.

Anti-Surge Protection Built-in anti-surge protection guards both vehicles' sensitive electronics against potentially damaging voltage spikes during the jump-start process — an essential feature for modern vehicles packed with ECUs and onboard computers.

Wide Vehicle Compatibility The BCS11 is compatible with both 12V and 24V electrical systems, making it suitable for petrol engines up to 5.5 litres and diesel engines up to 3 litres. Ideal for use with cars and light commercial vehicles.

What vehicles are the Draper BCS11 booster cables compatible with? The BCS11 is compatible with 12V and 24V electrical systems. It is suitable for petrol engines with a maximum capacity of 5.5 litres and diesel engines up to 3 litres, covering the majority of cars and light commercial vehicles.

What does the LCD display show on the BCS11? The built-in LCD displays real-time battery voltage and alternator charge rate, allowing you to assess the condition of your vehicle's battery and charging system — a useful diagnostic feature beyond basic jump-starting.

Why do the BCS11 booster cables have LEDs? The eight illuminating LEDs provide localised lighting around the engine bay, making it easier and safer to connect and disconnect cables in poor light conditions — ideal for night-time breakdowns or dimly lit garages.

What is anti-surge protection and why does it matter? Anti-surge protection limits voltage spikes that can occur during jump-starting. Modern vehicles contain sensitive electronics, ECUs, and onboard computers that can be damaged by power surges — this feature provides important protection for both the donor and recipient vehicle.

How long are the Draper BCS11 booster cables? The cables are 3.5 metres long and 29mm² in cross-section, offering ample reach between two vehicles while delivering the high current capacity needed for reliable engine starting.

Are the BCS11 jump leads easy to store? Yes — the cables retract onto a built-in reel using the integrated winding handle, keeping them neatly stored inside the plastic carry case with no tangling. Perfect for keeping in the boot of a car without the usual cable mess.
