The Ancor 255101 Marine Grade® Battery Lug Kit is a professional-grade, 100-piece assortment of tinned copper battery lugs engineered for reliable, corrosion-resistant electrical connections in demanding marine environments. Built from heavy-duty pure copper and finished with a tin coating, these lugs deliver maximum current flow and long-term durability — even in saltwater and high-humidity conditions. The closed-end barrel design seals out moisture, preventing oxidation at the crimp point.
This kit covers the most common AWG wire gauges and stud sizes used in marine battery and power distribution wiring, making it an ideal all-in-one solution for new builds, rewires, and service work.

Parts Desk Insights
This kit is our top recommendation for marine electricians and serious DIYers who want a single, organized assortment covering the full range of heavy-gauge battery lug sizes. The tinned copper construction is the correct choice for any saltwater or coastal application — bare copper lugs oxidize quickly and increase resistance over time. The closed-end barrel is a meaningful upgrade over open-barrel lugs, as it prevents moisture wicking up the wire strands. Best used with a quality ratcheting lug crimper for a gas-tight, code-compliant crimp. Pair with Ancor 90° Tinned Copper Battery Lugs #2/0 5/16" or Ancor 90° Tinned Copper Battery Lugs #2/0 3/8" when angled terminations are needed in tight engine compartments.
