ELECTRICAL POWER SYSTEMS SURVEILLANCE REOUIREMENTS (Continued) 2.

The pilot cell specJfic gravity, with electrolyte level within manufacturer's limity and corrected to 770F, is,gl.200 3.

The pilot cell voltage is 12.1 volts, and 4.

The overall battery voltage is 1125 volts.

b.

At least once per 92 days by verifying that:

1.

The voltage of each connected cell is 12.1 volts under float charge; 2.

The specific gravity, with electrolyte level within manufacturer's limits and corrected to 770F, of each connected cell is 1 200 1

and has not decreased more than 0.03 from the value observed during the previous test, and 3.

The electrolyte level of each connected cell is between the minimum and maximum level indication marks.

c.

At least once per 18 months by verifying that 1.

The cells, cell plates, and battery racks show no visual indication of physical damage or abnormal deterioration, 2.

The cell-to-cell and terminal connections are clean, tight, free of corrosion and coated with anti-corrosion material, 3.

The Battery Chargers Nos. 1, 2, and 3 will supply at least 300 amperes at 132 volts for at least 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 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 emergency loads for 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> when the battery is i

subjected to a battery service test.

e.

At least once per 60 months, during shutdown, by verifying that the battery capacity is at least 80% of the manufacturer's rating when subjected to a performance discharge test. This performance discharge test may be performed in lieu of a battery service test when it is scheduled to be performed at the same time as a battery service cest, but battery service tests must still be performed at 18-month intervals.
