Just as the question says. It occured to me while tightening a terminal up today (Didn't strip it, don't worry) that lead is an awful material to use for that purpose. It isn't overly conductive, it's strength is pathetic and the cherry on top is that it's a health concern. So why use it? I could see if it was a resistance to the lead acid, but sure a lead "cover" could lead to a stronger, more conductive metal at the terminal itself? Between aluminum, copper and steel, I can think of much better candidates for terminals. Anybody know? ------------- Never shift into reverse without a back-up plan. |

I think because it corrodes very slowly and it's easy to cast into any shape. It's already part of the battery so why not go all the way to the terminals. Dawg ------------- You dream it up....I'll make it |

I had no idea, but I was curious so I searched Google and ended up finding http://www.kimballmidwest.com/catalog/MarketingText/BI-METAL%20BATTERY%20TERMINALS.pdf - this . ------------- 88 Formula 5 speed |

That's a cool find, Colby. Kinda seems to satisfy most of my concerns with lead. I guess the mallibility does make sense, in retrospect. For our side-posts though, I still feel like that's a flaw more than an advantage though. The side terminals are never 100% snug fits anyways, so the soft lead doesn't help there. All is does is damage easily.
I suspect you're likely right, Damien. Cheap and easy. ------------- Never shift into reverse without a back-up plan. |
