The test sample battery should be placed on a flat surface. A rod with a diameter of 15.8 mm is placed in the center of the sample in a crisscross pattern. A 9.1kg weight dropped onto the sample from a height of 610mm. Each sample battery only needs to withstand one impact, and a different sample should be used for each test. The safety performance of the battery is tested by different weights and different force areas from different heights, and the test is carried out in accordance with the regulations. The battery should not catch fire or explode.
