Sea-Dog 6 AWG Black Tinned Copper Battery Cable, 500 ft Spool
Sea-Dog 6 AWG Black Tinned Copper Battery Cable, 500 ft Spool — Product description
This is Sea-Dog's 6-gauge battery cable on a full 500-foot spool, tinned copper under black insulation. It's the heavy wire you pull for battery banks, windlasses, and inverter runs where voltage drop matters. Tinned strands shrug off the salt air and bilge damp that corrode bare copper, and it carries ABYC and UL certification so your survey and insurance stay happy.
When you're wiring a battery bank or running power to a windlass, 6-gauge is the size you reach for. This Sea-Dog cable comes as a 500-foot spool of black, tinned-copper conductor, so you can cut exactly the runs your boat needs and keep the leftover on the reel for the next project.
The reason it's tinned matters. Bare copper corrodes fast in the damp, salty air down in a bilge or an engine room, and that green crust adds resistance right where you don't want it. Every strand here carries a tin coating, so the wire stays bright and conductive for years. The fine-strand construction also flexes around tight corners without fighting you.
It's rated to ABYC and UL standards, which is what a surveyor or insurer wants to see on primary DC wiring. Use it for battery cables, inverter and charger leads, bow thruster feeds, and any high-current run where a little voltage drop turns into a real problem.
Key Features
- 6 AWG gauge handles high-current DC runs like battery, windlass, and inverter feeds with minimal voltage drop
- Tinned copper strands resist the corrosion that eats bare wire in damp, salty bilges
- 500-foot spool lets you cut every run to length and keep the remainder for later jobs
- Fine-strand construction stays flexible for routing around tight corners and through conduit
- ABYC and UL certified for primary marine DC wiring that passes survey

Frequently asked questions
What gauge and length is this cable?
It's 6 AWG (6-gauge) and ships as a single 500-foot spool of black cable. You cut it down to the runs your boat needs.
Why tinned copper instead of plain copper?
Tinned strands hold up to the salt air and moisture in a bilge or engine room. Bare copper corrodes and builds resistance right where your high-current runs can't afford it.
Is it approved for marine use?
Yes. It's certified to both ABYC and UL standards, which is what surveyors and insurers look for on primary DC battery and charging wiring.
What can I use 6-gauge cable for?
It's sized for high-current DC circuits: battery cables, inverter and charger leads, windlass and bow thruster feeds, and similar runs where voltage drop matters.
