What is the best metal for battery terminals?
Brass battery terminals are much harder than either copper or lead, and should be soldered when possible, but they will hold up best in a corrosive environment. Lead battery terminals are easiest for the layman to work with, and can often be installed using just basic tools.
What is the best battery terminal material?
Brass and stainless steel construction resistant to corrosion from both weather and battery acid. Compatible with most standard post-style batteries. Better electrical conductivity than lead or zinc-plated terminals.6 Oct 2021
Why does positive battery terminal have cover?
the battery terminal covers can protect you and your battery's terminals from moisture and dust. Which may lead to rusting or short circuits. the battery terminal covers can protect your battery terminals from corrosion about the Saline and alkaline environment, Prevent your battery terminals from aging quickly.

Is brass or lead better for battery terminals?
In terms of battery terminals, brass is ideal because it does not rust unlike lead terminals that leave a powder like green substance when in contact with acids that the batteries have. Brass battery terminals also retain the connections better than lead terminals because of resistance to rust and plating choices.11 Aug 2017
