Projecta BT620-N10 Negative Saddle With Dual Auxiliary Brass Battery Terminal, Bag of 10

Quick answer

The Projecta BT620-N10 is the Negative Saddle With Dual Auxiliary Brass Battery Terminal, Bag of 10. Two auxiliary outlets take 5 to 15 mm², 10 to 6 B and S cable, handy for a fridge feed, isolator or charger lead without stacking lugs.

Bag of 10 negative saddle with dual auxiliary terminals, so this one is aimed at workshops restocking the drawer rather than a single car. Two auxiliary outlets take 5 to 15 mm², 10 to 6 B and S cable, handy for a fridge feed, isolator or charger lead without stacking lugs. The main cable clamps under the saddle while the auxiliary outlets handle lighter accessory wiring.

Material is forged brass, a solid choice for battery connections. Positive posts are slightly larger than negative posts, so fit this one only to the negative side.

Before fitting, clean any corrosion off the post so the terminal seats properly. Main cable range is 20 to 35 mm², 4 to 2 B and S.

Measure the post and the cable before ordering; a terminal that is too big for the post will never clamp properly. After fitting, a thin smear of terminal grease or spray protector slows corrosion. If the old terminal was badly corroded, cut the cable back to clean copper before fitting the new one.
