- 1. Degradation is defined as a decrease in battery capacity of more than 10%
l of capacity from its previous performance test, or the battery capacity is less than 90% of the manufacturer's rating.
- 2. Once per 60-month interval, this performance discharge test may be i
l' performed in lieu of the battery service test required by Specification 4.8.2.ld.
l l
- 3. The battery can be restored to a 60-month test interval by cell replacement if performance test results indicate that cell replacement will restore the battery to a minimum of 90% of rated capacity with no degradation.
Replacement cells must be tested to demonstrate a minimum capacity of 100% of the manufacturer's rating prior to installation.
l
- 4. Once per 24-month interval, a modified performance discharge test may be performed in lieu of the battery service test required by Specification 4.8.2.ld.
A modified performance discharge test is a test of the battery capacity and its ability to provide a high rate, short duration load (usually the highest rate of the duty cycle).
- 5. When battery life is greater than 85% of the expected life of the battery and degradation is indicated, cell replacement shall not be used to restore the capability of the battery for more than one year, and the battery shall be replaced within one year of the date of the discovery of the cell degradation.

Amendment No. 50 (Unit 2)
ELECTRICAL POWER SYSTEMS BASES A.C. SOURCES. D.C. SOURCES. and ONSITE POWER DISTRIBUTION (Continued)
The Surveillance Requirement for demonstrating the OPERABILITY of the station batteries are based on the recommendations of Regulatory Guide 1.129,
" Maintenance Testing and Replacement of Large Lead Storage Batteries for Nuclear Power Plants," February 1978, and IEEE Std 450-1975, "IEEE Recommended Practice for Maintenance, Testing, and Replacement of Large Lead Storage i
Batteries for Generating Stations and Substations," and 484-1975 " Recommended Practice for Installation Design and Installation of Lead Storage Batteries for Generating Stations and Substations."
Verifying average electrolyte temperature above the minimum for which the battery was sized, total battery terminal voltage on float charge, connection resistance values, and the performance of battery service and discharge tests ensures the effectiveness of the charging system, the ability to handle high discharge rates, and compares the battery capacity at that time with the rated capacity.
Table 4.8-2 specifies the normal limits for each designated pilot cell j
and each connected cell for electrolyte level, float voltage, and specific gravity. The limits for the designated pilot cells float voltage and specific gravity, greater than 2.13 volts and 0.015 below the manufacturer's full charge specific gravity or a battery charger current that had stabilized at a low
^
value, is characteristic of a charged cell with adequate capacity.
The normal limits for each connected cell for float voltage and specific gravity, greater than 2.13 volts and not more than 0.020 below the manufacturer's full charge specific gravity with an average specific gravity of all the connected cells not more than 0.010 below the nanufacturer's full charge specific gravity, ensures the OPERABILITY and capability of the battery.
Operation with a battery cell's parameter outside the normal limit but within the allowable value specified in Table 4.8-2 is permitted for up to 7 days. During this 7-day period:
(1) the allowable values for electrolyte level ensures no physical damage to the plates with an adequate electron transfer capability; (2) the allowable value for the average specific gravity of all the cells, not more than 0.020 below the manufacturer's recommended full charge specific gravity, ensures that the decrease in rating will be less than the safety margin provided in sizing; (3) the allowable value for an individual cell's specific gravity, ensures that an individual cell's specific gravity will not be more than 0.040 below the manufacturer's full charge specific gravity and that the overall capability of the battery will be maintained within an acceptable limit; and (4) the allowable value for an individual cell's float voltage, greater than 2.07 volts, ensures the battery's capability to perform its design function.
