Unique-Bargains Battery Terminal Clamps Copper 13mm 11mm 1 Pair

Copper battery terminal pair

This pair supplies a positive copper clamp with a 13 mm inner diameter and a negative copper clamp with an 11 mm inner diameter. Both terminals are machined from copper for conductivity and corrosion resistance. Threaded posts are pre-cut so no separate nuts are required during installation. The set suits automotive, RV, marine and small-boat electrical systems.

Vehicles needing 13 mm positive

Builders working on cars, trucks, RVs, campers, small yachts or boats that use these two post sizes can install the clamps directly. The copper construction handles battery extension, parallel links and ground connections. Buyers whose batteries use different post diameters or who require a different metal should select another terminal set.

13 mm positive and 11 mm negative inner diameters

The positive clamp accepts a 13 mm post and the negative clamp accepts an 11 mm post, matching the most common automotive polarity sizing. Thread diameters are 6 mm on the positive side and 5.6 mm on the negative side. Overall dimensions are 40 mm × 28 mm × 20 mm. These measurements determine whether the clamps fit the battery posts in hand.
