b. At least once per 92 days and within 7 days after a battery discharge with battery terminal voltage below 105 volts, or battery overcharge with battery terminal voltage above 150 volts, by verifying that:

1. The parameters in Table 4.8-2 meet the Category B limits,

2. There is no visible corrosion at either terminals or connectors, or the connection resistance of these iteas is less than

~

150 x 10 ohms, and

3. The average electrolyte temperature of six connected cells is above 64'F.

c. At least once per 18 months by verifying that:

1. The cells, cell plates, and battery racks show no visual indication of physi~el damage or abnormal deterioration,

2. The cell-to-cell and terminal connections are clean, tight, and coated with anticorrosion material,

3. The resistance of each cell-to-cell and terminal connection is less than or equal to 150 x 10 ohms, and

4. The battery charger will supply at least 400 amperes for batteries A and 8 and 300 amperes for batteries C and D at 125 volts for at least 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />.

d. At least once per 18 months, during shutdown, by verifying that the battery capacity is adequate to supply and maintain in OPERABLE status all of the actual or simulated emergency loads for the design duty cycle when the battery is subject"d to a battery service test.

e. At least once per 60 months, during shutdown, by verifying that the battery capacity is at least 8% (Exide) or 90'I (ATIIT) of t.he manufacturer's rating when subjected to a performance discharge test.

This performance discharge test may be performed in lieu of the battery service test required by Surveillance Requirement 4.&.2.ld.*

f. Annual 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 lOX, (Exide) or 5'X (ATILT) of rated capacity from its average on previous performance tests, or is below 90'X (Exide) or SSX (ATILT) of the manufacturer's rating.
