![]() After charging 1C for 6 hours, the battery is allowed to have alkali crawling and leakage, but not allowed to have explosion and deformation. Charge the batteries with qualified capacity for 105 minutes (1C), and test the batteries with phenolphthalein test solution for alkali crawling and liquid leakage.ĭischarge(1C) the battery to 1.0V/ CE11 for normal (For NI-CD)ī. Charge the batteries that pass the capacity test continuously for one month, and then discharge them to 1.0V/ CE11 for more than 56 minutes.Ī. If the actual capacity of the battery is subtracted from the capacity of the battery used for discharge, the capacity decrease shall not be more than 10%.Ĭ. Charge the battery for 90 minutes and leave it for 72 hours before discharging it to 1.0V/ CE11 to calculate the discharge capacity.1C1Cī. ![]() The internal resistance of a premium AA battery must not be greater than 22mΩ, and that of a common AA battery must not be greater than 25mΩ.Ī. The internal resistance of superior SC batteries shall not be greater than 8 mΩ The internal resistance of ordinary SC batteries should not be greater than 10 mΩ, and the second level: 12mΩ.Ĭ. After charging for 90 minutes for the third time, the battery should be used for 30 minutes to measure its internal resistance with the battery internal resistance tester.ī. 5.Detection of battery internal resistance:Ī. Cycle three times to calculate the last discharge capacity. Charge the battery for 90 minutes and record the highest voltage when charging, set aside for 30 minutes and then discharge to 1.0V/ CELL. Before the first charge, the battery should be discharged to a single 1.0V, and then the battery should be charged for testing 0.2C.ī. ![]() redness around the positive electrode cap) and record the open circuit voltage. Before the test, the battery should be numbered on the battery first, and phenolphthalein should be used to test whether the battery has alkali crawling, liquid leakage (i.e. The open-circuit voltage of ni-MH batteries must be greater than 1.25V when all batteries in stock are shelved for more than 15 days.1.0-1.24V is grade TWO, and below 1.0V is waste.Ī. Battery voltage greater than 1.15V/ CELL is qualified, 0.8V-1.14V/ CELL is second grade, 0.8V-0.5V is defective, and 0.5V is waste (applicable to Ni-CD battery).Ĭ. All incoming battery open circuit voltage must be greater than 1.2V/ CELL (not charged) or greater than 1.25V CELL (charged) (for NI-CD batteries).ī. ![]() Batteries placed in the inspection area are sampled at the AQL-J1 level specified in the sampling standard.The minimum sample quantity of each lot shall not be less than 30 PCS.Ī. All incoming batteries must be packed in accordance with the requirements of the order, no damage or mismarked or unclear ī. Printing contents of all battery jackets must meet the requirements of the order, no printing error, backjet, jacket breakage and other undesirable phenomena are allowed.Ī. ![]()
