Overcharge test requirements
The cell was tested at an ambient temperature of 20 ± 5 ° C (68 ± 9 ° F) and a supply voltage sufficient to maintain a 10 times C5 ampere rate throughout the test period at a constant charge current of 10 times C5 ampere. During the test, the temperature was measured on the internal battery casing of each sample. A supply voltage sufficient to maintain a 10x C5 ampere rate throughout the test period should be used at a constant charge current of 10 times the C5 ampere rate. During the test, the temperature was measured on the internal battery casing of each sample. The test will continue until the battery or battery explosion, vent or single operating protection device is in operation, and the temperature inside the battery's internal casing has stabilized or returned to ambient temperature. If the PTCor's other resettable protection device is working during the test, it should be reset at least 10 times.
