We replaced the batteries in the APC Matrix 5000 Smartcell but the light still says "bad battery". The microprocessor chip has been reset by jumpering # 17 and # 20 ,which usually works to reset "bad battery" but not this time. The battery monitor board was moved to another pack and the problem moved with it. Can we still buy these boards? We bought several 4 years ago from Pro Source for $80.00 each. In an unrelated problem the Estimated run time stays at zero even with new batteries and passing battery tests and battery calibration test. The book indicates the battery calibration test would be used until run down the batteries 25% to check calibration but they didn't seem to. Any advice and a lead on circuit board source would be much appreciated
