1、 Product Usage:
The test sample battery should be placed on a flat surface. A 15.8mm diameter rod is placed in a cross shape at the center of the sample. A 9.1KG weight fell from a height of 610mm onto the sample. Each sample battery only needs to withstand one impact, and different samples need to be used for each test. By testing the safety performance of the battery with different weights at different heights and different force areas, according to regulations, the battery should not catch fire or explode.
2、 According to standards and testing requirements:
GB 31241-2014 “Safety requirements for lithium-ion batteries and battery packs for portable electronic products”
Standard requirements:
After fully charging the battery according to the prescribed test method, place the battery on the surface of the platform, and place a metal rod with a diameter of 15.8mm ± 0.2mm horizontally on the surface of the geometric center of the battery. Use a weight of 9.1kg ± 0.1kg to freely fall from a height of 610mm ± 25mm and impact the surface of the battery with the metal rod, and observe for 6 hours. When conducting impact tests on cylindrical batteries, it is required that their longitudinal axis be parallel to the surface of the heavy object, the metal rod be perpendicular to the longitudinal axis of the battery, and only the wide surface of square batteries and flexible packaging batteries be subjected to impact tests. When conducting impact testing on button type batteries, the metal rod is crossed across the center of the battery surface. Only one impact test will be conducted on one sample.
Acceptance criteria: The battery should not ignite or explode.

B. The cylindrical or angular shape should have its longitudinal axis parallel to the plane and perpendicular to the center position of the transverse specimen, so that the longitudinal axis of the curved body with a diameter of 7.9mm (5/16 inch) can withstand the impact.

Standard requirements:
The battery is placed on a flat surface and a steel column with a diameter of 15.8mm ± 0.2mm is placed at the center of the battery. The longitudinal axis of the steel column is parallel to the plane, allowing a weight of 9.1kg ± 0.1kg to freely fall from a height of 610mm ± 25mm onto the steel column above the center of the battery. After the test is completed, observe for 6 hours. When the battery undergoes impact testing, its longitudinal axis is parallel to the plane and perpendicular to the longitudinal axis of the steel column. Each battery can only undergo one impact test;
Acceptance criteria: should not ignite or explode.
