Battery with 27 cycles NOT charging - stuck on 62% with Amperage (mA): 0

Question

Hi All,
I replaced a 312 cycles bulging battery last October with a third party one that has been fine until last night. My son was playing WOW (which was running from his external firewire HDD) and also watching a DVD while running on the battery ONLY. It suddenly shut down with the battery at 62% and now will not run off the battery. When the magsafe charger is connected it starts up OK, but the LED on the plug remains green, and battery info says -
Battery Information:
Battery Installed: Yes
First low level warning: No
Full Charge Capacity (mAh): 5957
Remaining Capacity (mAh): 3719
Amperage (mA): 0
Voltage (mV): 11610
Cycle Count: 27
AC Charger Information:
Connected: Yes
Charging: No
I have searched this part of the forum for possible solutions, and reset the SMC, with no change to the situation. I have not yet tried resetting the PRAM. This morning I was able to try a battery from another MacbookPro, and it started up and ran fine, and the charger when connected went orange and charged correctly. This would seem to confirm that all is OK with my MacbookPro's SMC and that the problem lies with the battery status not now being correctly "seen" by the MacbookPro. I read somewhere in my searches that the battery has its own microchip controller, and so am wondering if the sudden shutdown was due to the battery current capacity being exceeded by the demands of the fully worked processor running WOW, and the external firewire drive plus DVD running - and the software running the battery's controller becoming corrupted. If this was the case, can the battery controller be fixed, "re-booted" or re-installed somehow? Anyway, any advice will be gladly received at this point, even if the news is that my son's actions have now "killed" the battery and its time for another one!

Thanks Michael and Rod for your responses, and thanks Rod for suggesting the local battery specialist who I will contact tomorrow. In the meantime, casting my search wider through Google, looking for information on how to possibly re-condition MacbookPro batteries, I found some information in another forum that stated:
+sudden shutdown is a very clear symptom of a failed internal cell.+

+sure. the cell can be charged, it just doesn't hold the charge for very+
+long. That cell is first to discharge and then it might reverse charge+
+from the other healthy cells. The output voltage of the battery pack+
+drops, and if it drops below the minimum to run the computer, it+
+suddenly shuts down with no warning.+
. . . so I am now wondering if the battery may have one cell that is not as good as the others, and the intensive drain caused the sudden shutdown when the battery voltage dropped when that cell was depleted. If that was the case, the battery may be fine for normal use for many cycles yet if the depleted cell can be given a kick start possibly by a battery re-condition expert such as you suggest. I will follow this course and report their findings.
Thanks!
