Sea-Dog 4 AWG vs 2 AWG Tinned Marine Battery Cable Spools
Sea-Dog offers tinned-copper battery cable in both 4 AWG and the thicker 2 AWG size. These marine-grade cables come as bulk spools with bare ends, so they are suitable for custom-length battery leads when properly sized and terminated. Compare the exact black, red and yellow spool part numbers before ordering; an AWG designation alone does not tell you how many feet are supplied.

The exact MPN determines the wire size and the length supplied. All products listed are bulk, unassembled marine cable, not completed battery leads.
| Sea-Dog MPN | Wire gauge | Jacket colour | Spool length | End style |
|---|---|---|---|---|
| 8004010 | 4 AWG | Black | 25 ft | Unterminated bulk cable |
| 8004011 | 4 AWG | Black | 50 ft | Unterminated bulk cable |
| 8004012 | 4 AWG | Black | 100 ft | Unterminated bulk cable |
| 8004017 | 4 AWG | Black | 500 ft | Unterminated bulk cable |

| 8002022 | 2 AWG | Red | 100 ft | Unterminated bulk cable |
Gauge selection matters. 4 AWG and 2 AWG are not interchangeable solely because both use tinned copper. In American Wire Gauge, a lower gauge number indicates a larger conductor. The 4 AWG selections shown here include a 500-foot black spool, while the available 2 AWG products include shorter black and red lengths.
Common marine cable construction
Sea-Dog specifies annealed, finely stranded tinned copper for corrosion resistance and flexibility in marine installations. Its battery cable is oil-resistant, UL-listed boat cable, made in the USA, with a published 600V insulation rating and temperature ratings of 105°C dry / 75°C wet. This is bulk cable without fitted battery lugs, clamps or auxiliary wires.
The Sea-Dog battery cable manufacturer's chart identifies the gauges, colour combinations, spool lengths and standard packs.
Choosing cable for the intended electrical circuit
- Determine the required AWG size from the equipment specifications and the circuit's conductor-sizing calculation. Gauge alone does not establish a safe universal amp rating.
- Measure the complete routing length, including slack and service loops; select the manufacturer-listed spool length that will cover the installation.
- Use the correct insulation colour for the intended circuit and applicable marine wiring conventions, while verifying the actual polarity independently.
- Choose compatible lugs, correct crimping tools and adhesive heat shrink for the cable gauge and stud diameter. These bulk cables are supplied with bare, unterminated ends.
- Verify cable protection, overcurrent devices, abrasion prevention and approved routing before energizing the battery circuit.
