Sea-Dog 2 AWG Red Battery Cable, 25 ft Tinned Copper
Sea-Dog 2 AWG Red Battery Cable, 25 ft Tinned Copper — Product description
This is Sea-Dog's 2 AWG battery cable in red, sold as a 25 foot spool of tinned copper. It's built for the positive side of your marine power runs, from the house bank to a windlass, inverter, or main bus. UL and ABYC certified, and it ships without terminals so you can crimp it to your own layout.
When you're running heavy DC current on a boat, the cable matters as much as the battery behind it. Sea-Dog's 2 AWG battery cable gives you a 25 foot spool of tinned copper in red, sized for the big loads: house banks, windlasses, inverters, bow thrusters, and main battery-to-bus runs. Two gauge is serious copper, so it handles the amperage without heating up or dropping voltage over a long run.
The tinning is the part that earns its keep out on the water. Every strand is coated in tin, which is what keeps salt air and bilge moisture from creeping into the copper and turning your connection green. Bare copper corrodes from the cut end inward and slowly chokes off current. Tinned copper doesn't. That's why UL and ABYC both want to see it in a marine electrical system, and it's why this cable carries both certifications.
Red marks it as the positive conductor, so your color coding stays clean and the next person who opens the panel can read the run at a glance. It ships without terminals, which is exactly what you want for a real install. You measure the run, cut to length, and crimp on the lug that fits your stud. No fighting a pre-made cable that's six inches too short or a foot too long.
A 25 foot spool covers most single runs with cable to spare, or splits into a few shorter jumps between batteries and switches. Pair it with the black 2 AWG for the negative side and you've got a matched pair for a full power circuit. Whether you're rewiring a battery bank, adding an inverter, or just replacing a tired old cable that's gone stiff and corroded, this is the wire that does it right. Buy a little more than you think you need. It's always easier to trim a run than to splice one, and leftover 2 gauge never goes to waste on a boat.

Frequently asked questions
What gauge is this cable?
It's 2 AWG (2 gauge), a heavy conductor sized for high-current DC runs like house banks, windlasses, and inverters.
Is the copper tinned?
Yes. Every strand is tinned copper, which resists the salt-air and moisture corrosion that eats bare copper on a boat.
How much cable do I get?
You get a 25 foot spool. That covers most single power runs with length to spare, or splits into several shorter jumps.
Does it come with terminals or lugs?
No, it ships without terminals. You cut it to length and crimp on the lug that fits your studs, which is the right way to size a run.
Why is it red? Can I use it for the negative side?
Red marks it as the positive conductor to keep your DC color coding clear. For the negative side, use the matching black 2 AWG cable.
Is this cable certified for marine use?
Yes. It's both UL and ABYC certified, so it meets recognized marine electrical standards for construction and safety.
