Pilot cell. Designate a pilot cell on the basis of the test results for each battery
system's permanent record. With the battery shipped wet, it shall be the cell with
the lowest specific gravity after the battery is charged.
Enter acceptable tolerances in subparagraphs a and b, below. A 40 mV deviation from nominal volts per cell
(Vpc) is the normal maximum tolerance for lead-calcium cells. Lead antimony cell tolerance is normally 20 mV.
Specific gravity tolerance is normally +/- 10 points.
Production tests. Perform the following production tests at the factory:
Cell voltage measurement. The tolerance shall be [40 mV]
mV] from a nominal [2.25] [ ] V/cell.
Electrolyte gravity measurement. The tolerance shall be
( )] specific gravity points from a nominal
[10 (0.010)] [
[1.250] [ ] specific gravity.
Pressure-relief vent operation and reseal. Shall pass
manufacturer's standard test.
Cell-jar leakage test. The cell shall be pressurized with air and the
pressure shall remain constant.
Field tests. The Owner will perform a battery performance test in accordance with IEEE
450 on the fully-assembled batteries at the job site. The test will be based on the battery
manufacturer's ampere-hour rating of the battery. Seller may attend this test as noted in
Appendix B, paragraph 8.
Enter all shipping instructions. Batteries should normally be shipped wet and fully charged. It may be
advantageous to ask for special packing to facilitate handling the components when received, or grouping parts
in a way that facilitates installation. Special shipping instructions may also include a dedicated truck to expedite
Cleanliness. At the time of shipment, the equipment shall be clean inside and outside.
Remove all rust, oil, grease (except corrosion-inhibiting compound on cell posts), chalk,
crayon, and paint marks, and other deleterious material from all surfaces of the equipment.
Touch up any cuts, nicks, or scratches to the coating system.
a. Prepare equipment for shipment to protect it from damage during shipment and
b. Protect all openings to prevent damage, corrosion, and entrance of foreign matter
during shipment and storage.
