The AllSpark Battery Terminal Nut Cover is a practical, no-fuss safety accessory designed to protect exposed battery terminal nuts and bolts from accidental short circuits, corrosion, and contact damage. Made from durable, insulating plastic, each cover snaps firmly over the terminal nut to create a protective barrier — keeping bare metal away from tools, wiring looms, and conductive surfaces in tight engine bays, battery compartments, and dual-battery setups. Whether you're running a single cranking battery or a full auxiliary system, properly covered terminals are a simple but critical safeguard against costly electrical failures in the field.
Built for Australian caravan, camping, and 4WD enthusiasts who know that reliable 12V electrics are the backbone of any serious off-road or touring setup, these terminal nut covers are ideal for use on caravan battery boxes, camper trailer battery trays, motorhome auxiliary banks, and 4WD dual-battery systems. They're equally at home protecting the cranking battery under the bonnet as they are securing AGM, lithium, or deep-cycle batteries in your power system. Lightweight and easy to fit, they're an affordable way to maintain a tidy, safe, and compliant 12V installation — whether you're heading out on a weekend bush camp or a months-long remote Australia adventure.
