of discharge and every minute during discharge test.
d.
Record minutes and seconds when battery voltage drops below
minimum discharge voltage of 291 volts DC. On initial discharge
test, a battery may be expected to deliver 95 percent of its rated
capacity. This will increase to 100 percent after several
complete discharge cycles or after 12 months of float charge
service.
e.
Should battery fail to meet the requirements of the first
discharge performance test, open the inverted output breaker.
Then put battery on equalizing charge, with rectifier adjusted to
normal equalizing voltage of [424] [_____] volts DC. Equalize for
a minimum of [100] [_____] hours. Measure and record time and
battery voltage. Run a second discharge performance test.
3.5
FINAL ADJUSTMENTS
a.
Remove load bank and reconnect system for normal operation.
b.
Equalize battery at [424] [_____] volts for a period of [72]
[_____] hours.
**************************************************************************
NOTE: Delete this test if battery is sealed (valve
regulated) type.
**************************************************************************
c.
Bring electrolyte level of all cells up to the bottom of the high
level line by adding original filling gravity electrolyte.
d.
Resume charging battery at normal float voltage of [411] [_____]
volts DC.
e.
Check battery connections are properly torqued to manufacturer's
specifications. Take and record, for cell-to-cell and terminal
connections, detailed micro-ohm resistance readings. Remake
connections having a resistance of more than 10 percent above the
average.
f.
All manufacturer's data and operation manuals, which are an
integral part of, and shipped with UPS, shall be delivered to
Contracting Officer.
3.6
DISPOSAL
Upon completion of UPS installation and testing, Contractor shall remove
and dispose of empty, partially full and excess acid drums, including
shipping containers, obsolete batteries, and obsolete UPS modules. Removal
shall be accomplished off-base and in conformance with local laws and
regulations regarding disposal of hazardous material.
