Sealey Booster Cable Jump Leads with Electronics Protection 25mm 3.5mm

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.
