Sea-Dog 4/0 AWG Red Battery Cable, Tinned Copper, 100-Foot Spool
Sea-Dog 4/0 AWG Red Battery Cable, Tinned Copper, 100-Foot Spool — Product description
Sea-Dog's 4/0 AWG battery cable is a heavy-gauge, tinned-copper run for the high-amperage jobs on your boat. The red jacket marks the positive side, and it comes as a 100-foot spool with no terminals, so you cut and crimp to your exact length. UL and ABYC certified for marine work.
When you're running the main positive feed from a battery to a big load, thin wire won't cut it. This is Sea-Dog's 4/0 AWG battery cable, a heavy-gauge conductor built for the high-amperage jobs on a boat. Think windlass runs, inverters, bow thrusters, and big-engine starting circuits where voltage drop matters and the cable has to carry serious current without heating up.
The conductor is tinned copper, not bare. That tin coating is what keeps it from corroding in the damp, salty air below deck, and it's the reason this cable carries UL and ABYC certification for marine use. The red jacket marks it as your positive side, so your rigging stays clean and color-coded.
It ships as a 100-foot spool with no terminals attached. You cut it to the exact length you need and crimp on your own lugs, which is how most of us prefer to do a clean, custom run anyway. Buy the spool once and you've got cable on hand for the next few projects too.

Frequently asked questions
What gauge is this cable?
It's 4/0 AWG, a heavy conductor sized for high-amperage runs like windlass, inverter, bow thruster, and main engine starting circuits.
Is the copper tinned?
Yes. The conductor is tinned copper, which resists corrosion in the marine environment and is why it carries UL and ABYC certification.
Does it come with terminals?
No. It ships as a bare 100-foot spool without terminals, so you cut it to length and crimp on your own lugs.
What does the red color mean?
Red marks the positive conductor. Keeping positive runs red keeps your wiring color-coded and easy to trace.
How long is the spool?
It's a 100-foot spool, so you've got plenty of cable on hand for a run and future projects.
