I don't think that it's labeled wrong. I can't find a image of the EZ-flash PCB but I think the + side is the top connector and the - is on the bottom. On the battery the side with the text would be +.Oh! Maybe my battery is upside down!?! I have that battery in your amazon link. I never even thought about that. I mean, when is polarity labeled wrong??
If you look at the battery from the ebay link the + leads is on the bottom when the text is facing up.
