So I woke up this morning and my n810 is still charging it says?

Update:
I looked at my charger and I noticed it's bent, but still charges my n810, I am tempted to pre-order a battery online and trying that out, but is there any reason my battery would do this?

Second Update:
I talked to Nokia support to further see if I needed to buy a replacement battery and it was confirmed. Is the mugen power extended battery any good? Now I get to wait for a new battery and usb cable
