A “positive spin test” always results in a warranty replacement of the battery, but I don’t think it’s a requirement. You have the same symptoms of a bloated battery, so I’d guess you get it replaced even if it’s not really bloated.
They might ask you to try some other things first, e.g. maybe a hard reset. So it’s a good idea to make a backup e.g. with Titanium Backup while you wait for their reply.
Btw currently it may take longer than usual to get a replacement battery due to the move.
