Sea-Dog 6 AWG Red Battery Cable 25 ft | Tinned Copper
Sea-Dog 6 AWG Red Battery Cable 25 ft | Tinned Copper — Product description
Sea-Dog's 6 AWG red battery cable is the tinned copper positive lead you reach for when wiring a battery bank or feeding a panel. Twenty-five feet on the spool, built to ABYC and UL standards, and finely stranded so it bends into tight battery boxes without a fight.
Sea-Dog's 6 AWG battery cable is the red positive lead you reach for when you're wiring up a battery bank, running power to a panel, or replacing a tired cable that's been sweating green under the terminal. It's 25 feet on the spool, tinned copper through and through, and it's built to ABYC and UL standards so it'll pass a survey and hold up in the bilge.
The tinning is the part that matters out here. Bare copper looks fine the day you install it, then salt air and moisture creep into the strands and you get that green corrosion wicking up under the lug. Tinned copper puts a thin coat of tin on every strand, so the cable shrugs off the damp and keeps a clean connection for years. That's why ABYC calls for it on boats, and it's why we don't stock bare copper for battery work.
Six gauge is a real workhorse size. It's right for battery-to-battery jumpers in a house bank, feeding a distribution panel on a mid-size boat, or wiring a windlass or small inverter where the run isn't too long. The conductor is finely stranded, so it bends around bulkheads and into tight battery boxes without fighting you. Red marks it as your positive run. Pair it with the matching black for the negative side and your DC system stays easy to trace.
Twenty-five feet gives you room to do a job right, with enough left over to redo a cut if you fumble the first crimp. Strip it, crimp a tinned lug, add adhesive-lined heat shrink, and you've got a connection that'll outlast the boat. Keep in mind this is single-conductor cable, so you'll buy the red and black separately and size your runs to keep voltage drop in check on longer pulls.
If you're not sure whether 6 gauge is enough for your amperage and distance, give us a shout. Voltage drop math isn't hard, and we'd rather help you size it right than sell you a cable that runs warm.

Frequently asked questions
What's this cable used for?
It's marine battery cable. Use it for battery-to-battery jumpers in a house bank, feeding a distribution panel, or wiring a windlass or small inverter where the run isn't too long. Red marks it as your positive lead.
Why tinned copper instead of bare copper?
Bare copper corrodes in salt air. Moisture wicks into the strands and you get green corrosion creeping up under the lug, which kills the connection. Tinning coats every strand in tin so the cable stays clean and conductive for years. It's what ABYC calls for on boats.
Is red the positive or negative side?
Red is the positive convention on a DC system. Run the matching black cable for the negative side so your wiring stays easy to trace later.
Does 25 feet cover both my battery leads?
No. This is single-conductor cable, so 25 feet is one run of red. You'll buy the black separately for the negative side and size each run to your boat.
Is it ABYC compliant?
Yes. It's tinned copper, stranded, and built to ABYC and UL standards, which is exactly what a surveyor wants to see on battery wiring.
How should I terminate it?
Strip it clean, crimp a tinned copper lug, and finish with adhesive-lined heat shrink over the barrel. That gives you a sealed connection that shrugs off the damp.
Is 6 gauge enough for my run?
Depends on your amperage and the length of the run. Longer pulls need a bigger conductor to keep voltage drop in check. Check the ABYC ampacity tables or give us a call and we'll help you size it right.
