Many enterprises in export lithium battery before, all need to the third party testing institutions and grant the dangerous goods transport conditions. Will take samples to test, because lithium lithium ion batteries are very active element. In transit, if improper reinforcement, isolation, collision is too large, often causing incalculable disaster. The shipment before the test is to simulate various aspects environmental conditions, to detect the finished the safety of lithium-ion batteries. The test is very necessary.

So include those kind of test? The key, including acupuncture, impact and extrusion

Prick test is 18650 batteries will be recharged, use phi 3 mm of steel nails from in vertical direction through the battery on the surface of the longitudinal (steel needle to stay in the battery 1 min), don't fire explosion can be convicted as qualified.

Impact tests are will turn electric batteries, 9.1 KG weight from 0.61 m high free fall to 15.8 mm diameter steel bar (steel bar on the test battery). Don't fire explosion can be convicted for qualified.

Batteries with electricity, backlog test is be placed in between two flat extrusion of extrusion equipment, gradually increase the pressure to 13 kn, keep pressure for 1 min. Don't fire explosion can be convicted for qualified.
