Sealey Booster Cable Jump Leads with Electronics Protection

This 16mm x 3m booster cable set offers an excellent balance of power delivery and manoeuvrability for standard jump-starting applications. The 16mm cable gauge provides ample current capacity for most passenger vehicles, whilst the 3-metre length gives you sufficient reach between vehicles without excess cable to manage in tight spaces. The PVC-sheathed copper-coated aluminium construction ensures these cables remain flexible even in cold conditions, resisting oil, grease and most acids encountered in typical automotive environments. Insulated heavy-duty clamps reduce heat buildup during power transfer, protecting both the cables and vehicle electrical systems. The intelligent LED display unit continuously shows battery voltage, helping you diagnose charging system issues, whilst the reverse polarity indicator with audible alarm prevents potentially catastrophic connection errors. Additional built-in diagnostics allow you to check alternator charging performance and assess overall battery condition, making these cables a valuable diagnostic tool as well as emergency equipment. The in-line surge protector guards sensitive vehicle electronics against voltage spikes during the starting process. Everything stores neatly in the included protective case.
