4.4 Tests.
4.4.1 Verification. Verification of tests shall be determined by review of test records and data. Results of prior testing of cells or batteries selected in accordance with 4.3 and tested in accordance with 4.4.6, capacity test; 4.4.7, retention of charge test; and 4.5, cycle life shall be acceptable to demonstrate conformance of batteries being furnished on current acquisition orders.
4.4.2 Conditioning of samples. If supplied in a charged-and-wet condition, the cell or battery may be brought to a fully charged state before discharging. If supplied in a charge-and-dry condition, the battery shall be initially conditioned in accordance with the manufacturer's instructions.
4.4.3 Electrical breakdown test. To determine conformance with 3.7, jars shall be tested in accordance with BCI-I-5. The voltage applied shall be 100 volts per mil of wall thickness.
4.4.4 Impact resistance. To determine conformance with 3.7.1, samples from jars shall be tested in accordance with BCI-I-5. The area of impact shall be the geometric center of the test specimen.
4.4.5 Acid-resistance test. To determine conformance to 3.7.4, jars and covers shall be tested in accordance with BCI-I-5.
4.4.6 Capacity test. To determine compliance with 3.15.1, cells or batteries shall be subjected to capacity tests in accordance with BCI-I-2.
4.4.7 Retention of charge test. To determine conformance with 3.15.3, the cells or batteries shall be fully charged with the specific gravity of each cell corrected to 77 °F (25 °C). The cell or battery shall then be allowed to stand on open circuit in an ambient temperature of 75 °F to 90 °F (24 °C to 32 °C) for a period of 14 days. At the end of the 14-day period, the specific gravity shall be measured and corrected to 77 °F (25 °C).
4.4.8 Electrolyte. The impurity values specified in O-S-801 (except organic matter) shall be determined by any recognized analytical test method (see 3.4).
4.4.8.1 Organic matter. Heat 200 milliliters of electrolyte in a clean beaker until the acid begins to fume strongly. To pass the test, there shall be no perceptible charring; a slight yellow color that appears when the acid is hot but disappears on cooling should be disregarded.
4.5 Cycle life. To determine conformance with 3.15.2, the cycle shall be determined in accordance with BCI-I-3. The cells shall be cycled two times a day but not less than 10 cycles per week. Verification shall be determined by review of acceptable test records and data showing compliance with the cycle requirement.
4.6 Non-conforming product. The contactor shall withhold non-conforming products from acceptance and initiate corrective action in accordance with MIL-STD-1916.
