Degradation is indicated when the battery capacity drops more than 10% of rated capacity from its average on previous performance tests, or is below 90% of the manufacturer's rating. 2D-11 has had one test performed prior to 10/12/99.

The capacity at that time was recorded to be 116.25% (JO-873102, microfilm

1. 64101381) and 106.5566% recalculated under CR-2-97-0444(JO-956320 on IDEAS). The measured capacity of the test being performed must be compared to the average of the tests previously accomplished. Should the measured capacity fall MORE THAN 10% below the 111.4033%, then the 2403.001 surveillance must be rescheduled to be accomplished every refueling outage 9.12 Battery capacity as measured during this test have been compared with the measured capacity observed during previous tests The capacity average or battery condition does warrant the performance of this test every refueling outage in the future.
