B2.1.1.4 As a result of the short circuit, the cell shall not explode or catch fire.B2.1.2 Cell abnormal charging B2.1.2.1 Two as received fully charged cells and two fully charged cells previously subjected to charge/discharge cycling outlined in B2.1.1.2 shall comply with the abnormal charging test of B2.1.2.2 –B2.1.2.4. B2.1.2.2 Cells shall be discharged to the manufacturer’s specified end of discharge conditions. Each test sample, at its specified operating temperature, is to be subjected to a constant current charging at the specified maximum charging current Ic until the maximum (abnormal) charging voltage as specified by the manufacturer is reached. Then the charging is continued using constant voltage charging at the maximum (abnormal) charging voltage for 7 h.B2.1.2.3 When an overcurrent device operates during the test, the test is repeated on samples with a charging inputs below the trip point of the protective device.B2.1.2.4 As a result of the abnormal charging, there shall be no fire or explosion
