The battery is tested at an ambient temperature of 20 + 5 ° C (68 + 9 ° f). Under a constant charging current of 10 times the C5 ampere rate, it is enough to maintain 10 times the C5 ampere rate throughout the test. The voltage is 6V in a single string multiplied by the number of strings. During the test, the temperature shall be measured on the internal battery shell of each sample. A supply voltage sufficient to maintain 10 times the C5 ampere rate throughout the test shall be used at a constant charging current of 10 times the C5 ampere rate. During the test, the temperature shall be measured on the internal battery shell of each sample. The test will continue until the battery or battery explosion, vent or single operation protection device works, and the temperature of the internal shell of the battery reaches a stable state or returns to the ambient temperature. If other resettable protective devices of ptcor work during the test, they shall be reset at least 10 times.
Result: no fire, no explosion.
