Test Conditions
Temperature: 45 ± 2℃ Leakage Characteristics Relative Humidity: ≤75% Storage: 30 Days Shall Be Inspected By Visual Means 4.1 Testing Condition (1) Temperature and Relative humidity Unless otherwise specified elsewhere, tests shall be conducted at ordinary temperature (20±2℃) 、Relative humidity (45%-75%). (2) Storage of test specimen batteries Specimen batteries to be tested shall be kept at the ambient temperature of 23 ±5℃、the relative humidity of 45%-75%. 4.2 Measuring instruments and devices (1) Measuring instruments Outer micrometers or dial gauges specified not less than 0.01mm, and vernier calipers specified not less than 0.02mm or those having equal or better accuracy shall be used. (2) DC voltmeters The tolerance shall be not less than 0.25% and the input resistance rating shall be 1MΩ or more. (3) Load resistance Load resistance shall include resistance throughout external circuits, and its tolerance shall be±0.5%.

4.3 Test methods Appearance of batteries shall be inspected by visual means. Dimension shall be measured with instruments specified in Subparagraph 4.2(1) above, provided that either one or both sides of such instruments shall be insulated in measuring the overall height of the batteries. (3) Open-circuit voltage Test specimen batteries shall be kept for 4 hours or longer at the ambient temperature specified in Table 1, and then the voltage between both terminals shall be measured at the same ambient temperature with a voltmeter as specified in Subparagraph 4.2(2). (4) Closed-circuit voltage Test specimen batteries shall be kept for 4 hours or longer at the ambient temperature specified in Table 1, and then the voltage between both terminals shall be measured with a voltmeter as specified in subparagraph 4.2(2) while the specified load resistance 4.2(3) is connected between both terminals at the same ambient temperature as specified above; provided that the measured value shall be based on meter reading taken 0.8 seconds after the circuit is closed. (5) Service life Test specimen batteries shall be kept for 8 hours or longer at the ambient temperature specified in Table 2.and shall then be continuously discharged at the same ambient temperature and through the specified load resistance. The discharge shall be continued until the terminal voltage of the test specimens falls below the discharge end-point voltage of 2.0V, and the time during which the terminal voltage has been maintained equal to and above the discharge end-point voltage shall be taken as the service life. (6) Service life at high temperature Test specimen batteries, stored at the temperature in Table 3, shall be kept for 4 hours or longer at ordinary temperature and at ordinary humidity (45 75%RH) and shall then be continuously discharged through the specified load resistance. The discharge shall be continued until the voltage falls below the discharge end-point voltage of 2.0V, and the time during which the terminal voltage has been maintained equal to and above the discharge end-point voltage shall be taken as the service life. Tests specified below shall be conducted as required. Except as specified in this paragraph. Test methods be in accordance with the provisions of Paragraph 4.4. (1) Electrolyte leakage test Test specimen batteries shall be examined for electrolyte leakage while they are kept at ordinary temperature and at ordinary humidity after having been stored at the temperature, humidity and period specified in Table 4.
