That’s interesting. I had a bad battery leakage issue recently. It was in an Apple Magic Trackpad and was so bad I could not get the battery cover unscrewed at all. I broke the glass trying and so I just threw the whole thing out. I don’t know for sure if it was Costco Duracells but we often buy those so most likely it was.
