Battery not Charging

Hello,

I have a 5 months old battery (GREENBOX - A1322) that was charging fine. Now, I don't know what happened that it no longer charges.

The magsafe power cable has the green light on indicating it's fully charged, but it isn't.

Charge Information:

Charge Remaining (mAh): 4187

Fully Charged: No

Charging: No

Full Charge Capacity (mAh): 4189

Health Information:

Cycle Count: 37

Condition: Service Battery

Battery Installed: Yes

Amperage (mA): 0

Voltage (mV): 12382

AC Charger Information:

Connected: Yes

ID: 0x0100

Wattage (W): 60

Revision: 0x0000

Family: 0x00ba

Serial Number: 0x002b46f4

Charging: No

If I unplug the power cable, my mac will power off in 2 minutes or so.

I already searched for solutions, and reset the NVRAM and PRAM. It didn't help.

I want to know if this is a hardware problem on my motherboard or it's the battery. I know the "Systems Information" is showing "Condition: Service Battery" which I believe tell you to replace with a new battery. However, I don't want to spend money buying a new battery and still have the same issue.
