MIL-PRF-8565/6B(AS)
"a. Perform the test of 4.5.32. Examine the battery for the requirements of 3.8.18.
Constant potential charge the battery in accordance with 4.4.2 for 5 hours at room temperature
(see 4.4.1).
"b. Stabilize the samples (see 4.4.1) at -18° C (-0°F) for sample 1, 15° C (59° F) for
sample 2, and 55° C (131° F) for sample 3. Perform 4.5.29.1.c through 4.5.29.1.g with the
battery in the environmental chamber at the specified temperature.
"c. Discharge each sample at the 1.0C-rate to a cutoff voltage of 20.0 volts.
"d. Examine the battery for the requirements of 3.8.17.1.
"e. Stabilize the samples at room temperature (see 4.4.1). Constant potential charge the
battery for 5 hours in accordance with 4.4.2.
"f. Stabilize the samples (see 4.4.1) at the temperatures of 4.5.29.1.b. Discharge each
sample at the 1.0 C-rate to remove all but 0.75 ampere-hours from each sample as determined by
4.5.29.1.d.
"g. Stabilize the samples (see 4.4.1) at the temperatures of 4.5.29.1.b. Constant potential
charge the battery for 30 minutes in accordance with 4.4.2.
"h. Immediately after completing 4.5.29.1.g, place the samples in a room temperature
environment (see 4.4.1). Discharge the samples at the 1.0 C-rate to a cutoff voltage of 20.0
volts.
"i. Examine the battery for the requirements of 3.8.17.1.
4.5.29.2 One-hour charge test. This test consists of the following steps.
"a. Perform the test of 4.5.32. Examine the battery of the requirements of 3.8.18.
Constant potential charge the battery for 5 hours in accordance with 4.4.2.
"b. Stabilize the battery (see 4.4.1) at -40° C (-40° F), Perform 4.5.29.2.c and 4.5.29.1.d
with the battery in the environmental chamber at the specified temperature.
"c. Discharge the battery at the 1.0 C-rate to a cutoff voltage of 20.0 volts.
"d. Stabilize the battery (see 4.4.1) at -40° C (-40° F). Constant potential charge the
battery in accordance with 4.4.2 for 1.0 hour.
