Sea-Dog 2/0 AWG Black Tinned Copper Battery Cable, 100 Ft Spool
Sea-Dog 2/0 AWG Black Tinned Copper Battery Cable, 100 Ft Spool — Product description
Sea-Dog's 2/0 AWG black negative battery cable on a 100-foot spool. Tinned copper conductor stands up to salt air, and it ships without terminals so you can cut every run to length and crimp the lugs your install needs. UL listed and ABYC compliant.
This is Sea-Dog's 2/0 AWG battery cable, sold by the 100-foot spool so you can cut runs to length and crimp your own lugs. It's the black negative conductor, the return side of your DC system, and it's built for the kind of high-amperage loads you find between a battery bank and a windlass, inverter, or bow thruster.
The conductor is tinned copper, not bare copper, and out on the water that matters. Tinning shrugs off the corrosion that eats into plain copper strands after a few salty seasons, so your connections stay low-resistance and your voltage drop stays where you designed it. The cable ships without terminals, which is what you want for a clean, custom install. Cut it, strip it, crimp the lug that fits your stud.
It's UL listed and it meets ABYC standards, so it'll pass a survey and do the job right. Pair it with the matching red positive spool for a complete run, and you're set.
Key Features

Frequently asked questions
Is this the positive or negative cable?
This is the black negative conductor, the ground return side of your DC system. For the positive leg you'll want the matching red 2/0 AWG cable.
Does it come with terminals or lugs?
No. It ships as bare cable on a 100-foot spool. You cut it to length and crimp on the lugs that fit your battery studs and posts.
Why tinned copper instead of plain copper?
Tinning coats each copper strand so salt air and moisture can't corrode it. That keeps resistance low and your connections reliable over years on the water.
What is 2/0 AWG cable used for?
It's heavy gauge built for high-current runs, things like battery bank interconnects, windlasses, inverters, and bow thrusters. Size the gauge to your amperage and run length using the ABYC tables.
