Pre-assembled marine battery leads save the work of crimping large terminal lugs, but the ready-made cable still needs to match your electrical system. Ancor offers tinned-copper assemblies in different AWG sizes, lengths, colours and lug-stud hole diameters. Use this chart to compare the specific models carried by NewRVParts.
Three measurements determine the right assembly
The 4 AWG and heavier 2 AWG versions have different conductor cross-sections. Size for the circuit and route.
Choose between an 18-inch or 32-inch assembly in this selection, with enough room for proper routing.
Models with black insulation use 5/16-inch lugs here; red-insulated versions use 3/8-inch lugs. Check both studs.

All six products are pre-assembled with tinned-copper lugs and adhesive-lined heat shrink at the connections.
| MPN | Wire size | Length | Insulation colour | Lug stud size |
|---|---|---|---|---|
| 189130 | 4 AWG | 18 in | Black | 5/16 in |
| 189131 | 4 AWG | 18 in | Red | 3/8 in |
| 189134 | 4 AWG | 32 in | Black | 5/16 in |
| 189135 | 4 AWG | 32 in | Red | 3/8 in |
| 189140 | 2 AWG | 18 in | Black | 5/16 in |
| 189141 | 2 AWG | 18 in | Red | 3/8 in |
Ancor specifies fine-stranded UL 1426 marine battery cable, flame-retardant UV-inhibited insulation and adhesive-lined 3:1 heat shrink on this assembly family.
Installation and cable-size checks
Choose cable cross-section from the equipment's specified current draw, installation length and voltage-drop requirements, not simply the space available around the battery. Then measure the route including bends, strain relief and maintenance access. Verify stud diameter at both ends; do not force a 5/16-inch lug onto a 3/8-inch stud or assume that red and black cables share the same hole size.
Do not interchange the 5/16-inch and 3/8-inch lug arrangements without verifying the terminal connection. Battery leads must also be correctly protected, routed and secured according to the equipment manufacturer's electrical requirements.
