New battery always at 50% charge

I recieved an iPhone 3GS from work that had a bad battery. I unlocked it with ATT, and then replaced the battery using your guide (thank you very much).
Once back together I has some issues getting the digitizer to work, but was finally sucessful. It appears that the phone is completely operational.
However When I first powered the phone up with the new battery, the battery showed about 50% charge. I left the phone to charge over night, and in the morning it still showed 50% charge.
Do you have any suggestions as how to diagnose where the problem lies?
