Battery Terminal Corrosion

Car batteries sometimes get white or blue-green corrosion on the terminals and hold-down clamps. This is a semi-common problem. I don’t see it a lot, but I see it enough for it to not surprise me. There’s a lot of chemistry that goes into causing it, stuff involving the different metals used in battery posts and clamps, and what happens when electricity flow through them.

This is one of the worse cases I’ve seen of battery corrosion. It’s typically just a little bit around the base, but this was a whole pile bigger than the positive terminal cover. If I remember right the customer didn’t buy the battery service I recommended. It’s a pretty simple service, we just spray battery cleaner on, scrub it with a wire brush, wash it off with water, blow the water off, and spray it with something that’s supposed to prevent it from happening again.


Thanks for reading, and if you want to get in touch, I’m on Facebook, Twitter, and Instagram!
