Battery Clamps/Battery Connectors

Battery connectors tend to get corroded due to the battery venting sulfuric acid vapors. If the corrosion is severe enough, it eats away the metal of the clamp that connects between the battery cable and the battery terminal. When replacing these, we generally use a marine style clamp that comes with an upright stud to bolt the cable ends to.

Alternatively we use a connector like the original connectors from Toyota. A kind of clamp that I hate to see is the style with a “clam-shell” portion that clamps onto the naked wire-end of the cable. I hate these, because they seem to be a magnet for hidden corrosion that leads to starting problems where the starter won’t crank.
