Laptop won't detect battery's charge

Mornin' everyone,

I bought a new battery for my macbook pro in January since the old one wasn't holding a charge anymore, and it had been working great up until yesterday where it now won't charge and the laptop refuses to run off the battery.

Pressing the button still shows that the battery has a charge, however if you unplug the computer it will shut off, and in the tool bar it says (Not Charging) and Condition: Replace Now

As said, the battery is only about 2 months old with 47 cycles on it. From the system profiler...

Battery Information:

Model Information:
Device name: ASMB012
Pack Lot Code: 0000
PCB Lot Code: 0000
Firmware Version: a41b
Hardware Revision: 0000
Cell Revision: 0000
Charge Information:
Charge remaining (mAh): 0

Charging: No
Full charge capacity (mAh): 0
Health Information:
Cycle count: 47
Condition: Replace Now
Battery Installed: Yes
Amperage (mA): -3
Voltage (mV): 11221

Since my wifi card seems to have randomly died yesterday and this is a pretty new battery, I'm wondering if all the hardware on my computer is messed up and it just is having a problem communicating with the battery, or is the battery actually dead?
Thanks!

That is probably the reason for it not working properly. Get an Apple battery in order to assure a proper working battery and getting a warranty with it. While the battery you bought is cheaper, it probably also comes with less "perfect" or matching components, thus it frells up. The Apple battery is more expensive due to the use of higher specced components and a little profit Apple wants to make.
The cheap battery probably costs around 10 to 20 USD to make, the Apple battery probably costs around 50 or 60 USD to make.
 
There may be a lot of reasons to why it's not charging. For instance, your adapter is broken. If it says replace now then it's very likely the battery issue. Contact the seller if there's warranty. If not then get another one.

I wouldn't trust or recommend any non-Apple battery, due to the number of problems reported with "knockoff" batteries. Also, there is no assurance that knockoff batteries have the same charging technology that Apple uses, involving the battery, the MagSafe adapter and the Mac's logic board.
