Record the voltages of every cell taken with the digital voltmeter on form
POM-133C. Take the voltages while on float and compare with previous
readings.

Check and record the electrolyte temperature of the pilot cell. Use
only an
alcohol thermometer reserved only for this battery. Mercury thermometers
may break and cause sparking or an explosion. Never insert a thermometer
or any tool ever used for other batteries into a ni-cad cell.

Check for general cleanliness of the battery, mounting rack, and battery
room.
Check for electrolyte leaks and cracks in cells and take corrective action if
found. Check for corrosion at terminals, connectors, racks, and cabinets.
Check the ambient temperature and make sure ventilation devices (fans and
vents) are operable. Check the charger for current and voltage output.

Check for availability and condition of all safety equipment, gloves, face
shields, aprons, etc. Check for a full gallon of labeled neutralizing solution
(20 ounces of boric acid per gallon of distilled water) and operability of body
wash/eyewash station or portable eyewash equipment. Check for availability
of insulated tools so short circuits can be avoided (see section 8).

BATTERY DISCHARGE TESTING
A. Acceptance Testing
A. Acceptance Testing
Acceptance testing may be done at the factory prior to shipping or at the
service location after the battery comes to equilibrium in charge and
temperature. The discharge rate should be constant at the full rated
current for the duration of the test. See the manufacturer's literature for
this information. Most manufacturers recommend a test duration of 3 to 8
hours for this test.

Note:
Temperature affects battery capacity. Take electrolyte temperatures of
individual cells and average them prior to the test. The test discharge
current is equal to the rated discharge current divided by the temperature
