The overall battery voltage is 2 120 volts.
b.
At least once per 92 days by verifying that:
1.
The voltage of each connected cell is 2 2.0 volts under float charge and has not decreased more than 0.17 volts from the value observed during the original acceptance
- test, 2.
The specific gravity, corrected to 77*F, of each con-nected cell is 2 1.205 and has not decreased more than 0.02 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:

At the completion of either of the above tests, the battery charger shall be demonstrated capable of recharg-ing its battary at a rate of at least 150 amperes while supplying normal D.C. loads. The battery shall be charged to at least 95% capacity in s 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
e.
At least once per 60 months during shutdown by verifying that the battery capacity is at least 80% of the manufacturers rating when subjected to a performance discharge test. This performance discharge test shall be performed subsequent to the satisfactory completion of the required battery service test.
