[spark21]

Hello. I have a 2021 Chevy spark with 3,500 miles. I was filling my washer fluid the other day and noticed this orange spot on the negative battery terminal, but no green corrosion. It looks to me like a discoloration in the metal. Can anybody tell me what they think and would it be considered an issue or leave it alone? Thanks. Attached is a photo.

Looks like the anti-corrosion spray that is sprayed on battery connectors. If it just showed up on there, I would have no idea without looking at the other terminal as well. See if its on the other one too, or under the terminals itself if you feel comfortable removing them.

It's only on the negative. There is no chalky corrosion, and if you wipe the orange spot wet nothing comes up on the paper towel. It looks like it wasn't dipped properly.

It looks to me like the batttery clamp may be copper, with anodizing on it (the silverish stuff). That spot just looks like copper to me.
