Quick answer

The Projecta BT21-10 is the Split Barrel Brass Battery Terminal, Box of 10. Size the cable first: this one is listed for 50 to 70 mm², 0 to 00 B and S. The split barrel lets you solder or crimp the cable straight into the terminal.

This is the 10 piece box of universal split barrel terminals, handy for workshops restocking the drawer. Size the cable first: this one is listed for 50 to 70 mm², 0 to 00 B and S. The split barrel lets you solder or crimp the cable straight into the terminal.

Forged brass conducts well and copes with the heat and vibration of an engine bay. Projecta electroplates these brass terminals with a nickel coating.

Listed as universal, so it is not tied to the positive or negative side. Before fitting, clean any corrosion off the post so the terminal seats properly.

Keep the positive covered so a spanner cannot bridge it to the body. If the old terminal was badly corroded, cut the cable back to clean copper before fitting the new one. Tighten firmly but do not crush the post; a lead post deforms easily. After fitting, a thin smear of terminal grease or spray protector slows corrosion.

Projecta lists 50 to 70 mm², 0 to 00 B and S for the main cable.
