Sealey Booster Cable Jump Leads with Electronics Protection

Sealey's professional booster cables combine superior electronics protection with robust construction for safe, reliable jump-starting. Available in sizes from 16mm to 25mm, these intelligent jump leads feature PVC-sheathed copper-coated aluminium cables that deliver maximum power transfer whilst remaining flexible in all conditions. The cables are engineered to resist oil, grease and most acids, making them ideal for demanding workshop environments.

At the heart of these booster cables is an advanced LED display unit that provides real-time battery voltage monitoring, ensuring you can assess the situation before attempting a jump-start. The integrated electronics protection system includes reverse polarity indication with audible alarm to prevent potentially damaging connection errors, plus an in-line surge protector that guards against electrical spikes. Additional diagnostic features include alternator charge checking and battery condition assessment, giving you comprehensive electrical system insights. Insulated heavy-duty clamps minimise heat transfer during high-current operations, whilst the included storage case keeps everything organised and protected between uses.
