These Battery Booster Cables are heavy‑duty jumper leads intended to transfer current between 12V vehicle batteries to restart a flat battery or provide temporary power. They consist of two insulated conductors terminated with robust spring‑loaded clamps and are designed for use in roadside recovery, workshops and vehicle maintenance where a rapid, reliable connection to conventional car, van or leisure batteries is required.

Each cable is constructed from multi‑strand electrolytic copper conductor to maximise flexibility and minimise voltage drop under load. Typical conductor cross‑sections available are 16 mm² and 25 mm², with PVC outer insulation rated for general automotive use and a working temperature range appropriate to engine‑bay environments. The clamps are steel with a copper‑plated contact surface and insulating handles; serrated jaws ensure a secure grip on standard top‑post and side‑post battery terminals. These leads are intended for 12V systems only and are not suitable for continuous use on 24V commercial systems.

Manufacture complies with relevant automotive cable practice and material regulations, including ISO 6722 for road vehicle single‑core cables, and components are supplied in accordance with RoHS/REACH chemical restrictions where applicable. Thread type, head type and drive type are not applicable to this product as it is a cable and clamp assembly rather than a threaded or driven fastener.

Typical applications include jump‑starting cars and light commercial vehicles, emergency roadside assistance, garage and workshop battery work, and use on leisure vehicles and small agricultural machinery. Industries that commonly use these cables include automotive repair, fleet maintenance, motorsport support, agricultural services and DIY enthusiasts.

Key benefits of these booster cables include good corrosion resistance provided by plated clamp contacts, a flexible stranded copper core for reliable current transfer and low internal resistance, and broad compatibility with standard 12V battery posts. The availability of different conductor cross‑sections means you can choose a set that balances portability with peak current capability for your needs.

Duchy Fasteners stocks a range of booster cable lengths and sizes, typically from 2.5 metres to 4 metres and in 16 mm² and 25 mm² cross‑sections, supplied in single sets or bulk packs—please contact us for current stock and pack options.
