e. At least once per 60 months during shutdown by verifying that the battery capacity is at least 80X (83.4X for the 250 Volt battery) of the manufacturer's rating when subjected to a performance discharge test. At this once per 60-month interval, this performance discharge test may be performed in lieu of the battery service test.

f. At least once per 18 months during shutdown performance discharge tests of battery capacity shall be given to any battery that shows signs of degradation or has reached 85K of the service life expected for the application. Degradation is indicated when the battery capacity drops more than 10K of rated capacity from its average on previous performance tests, or is below 90K (93.4X for the 250 Volt battery) of the manufacturer's rating.
