Sealey Booster Cable Jump Leads with Electronics Protection

This heavy-duty 25mm x 3.5m booster cable set delivers professional-grade performance for larger vehicles and demanding applications. The substantial 25mm cable gauge provides maximum current-carrying capacity for jump-starting commercial vehicles, 4x4s, or vehicles with larger displacement engines, whilst the 3.5-metre length offers extended reach for awkward parking situations or when assisting larger commercial vehicles.

Constructed with PVC-sheathed copper-coated aluminium cables, this set combines superior conductivity with practical flexibility and resistance to oil, grease and most acids. The insulated heavy-duty clamps are engineered to handle high currents whilst minimising heat transfer that could damage cable insulation or vehicle components. The sophisticated LED display unit provides real-time battery voltage readings, enabling proper assessment before attempting a jump-start, whilst the reverse polarity indicator with alarm prevents dangerous connection errors.

Integrated diagnostic features include alternator charge checking and battery condition assessment, allowing you to identify underlying electrical problems rather than simply providing a temporary jump-start. The in-line surge protector safeguards modern vehicle electronics from voltage spikes during the starting process. Complete with a robust storage case to keep these professional cables organised and protected.
