New 2032 battery has reversed polarity

Yes, they are cheap china bulk pack but I've never seen this before.
Glad no damage was done. Kind of makes me want to check these small lithiums before installing in sensitive electronics.

Wow that's crazy. If they are new you should be able to get some replacements.
