Replaced battery not charging!

Hi

I've just replaced my dead battery with a brand new one.

Oh my god I was happy when the phone I thought was dead booted up! The battery indicator were at 80% with the new battery. I were quite excited that I got it work so I didn't try charging it.

Later same day I plugged the phone into the wall for charging. The big green battery showing "Charging" came up as usual. 30 minutes later when I grab my phone I see that the phone has drained 10% battery instead of charging?

The battery indicator says it charging, I see the flash.

So I thought it would be a good idea to let it totally drain so I can charge fully to set a new chargingcycle.

When it was totally drained I put it in the wall charger again. The red battery image came up, as it use to do when the iphone is drained.

The problem is, the red image is still there, after 60 minutes in wallcharger.

What happend?

Bad replacement battery?

Hardware damaged during install of new battery?

Notice: The iphone indicates that it's connected to a charger, and it says that it's charging, but it will not charge.

Frustrating, couple of hours ago I was celebrating my achievments, but now im just crying ;-(
