Safety Question What is happening

Post image

Think my battery died and when I popped the case open this is what I saw. Can I still jump it?

Nope bears no relation to battery condition.

They did not test it. They just looked at it. Blue corrosion is no reason to reject a battery. It's the copper terminal that is corroding blue not the lead of the terminal post. It's just a minor leak of battery acid...so what?

I agree it’s not a big deal and where I worked we would have just sprayed it to get the corrosion off then taken the battery out and charged it.
