Buying Guide

Choose the correct gauge

Match cable AWG to your application: heavier starts (starter motors, inverters) typically require low AWG (4 AWG or 4/0 AWG) for safe current flow and minimal voltage drop

Check conductor material

Copper conductors offer superior conductivity; select copper battery cables when maximum current capacity and corrosion resistance are important

Match lug size and type

Confirm lug stud diameter (eg. 3/8 in or 5/16 in) and terminal compatibility with your switch, starter or inverter to ensure a secure, low-resistance connection

Consider length and routing

Choose cable length that accommodates routing from switch to starter or battery without excessive bending; longer runs increase voltage drop, so pick the shortest practical length

Prefer marine-grade or insulated options for exposure

For boats or exposed installations, select marine-grade or insulated cables with corrosion-resistant lugs to withstand moisture and salt environments
