T.6 crash test
9.1kg weight from 61 ± 2.5cm height falls on the battery with a 15.8mm round rod, the battery surface temperature.
T.7 overcharge test
Under 2 times the maximum continuous charging current and 2 times the maximum charging voltage, the battery overcharge 24h.
T.8 forced discharge test
Battery 12V series DC power supply, the maximum discharge current forced discharge.

Determine the test eligibility criteria

(A) In tests T.1 to T.6, no disintegration or fire occurred.
(B) In tests T.1, T.2 and T.5, the effluent is not a toxic, flammable or corrosive substance.

(A) Visual observation did not see the exhaust or leakage.
(B) Exhaust or leakage that did not result in a weight loss exceeding that shown in Table 38.3.4.7.1 has occurred.
(C) In tests T.3 and T.6, the effluent is not toxic or corrosive.
(A) Visual observation did not see the exhaust or leakage.
(B) Exhaust or leakage that did not result in a weight loss exceeding that shown in Table 38.3.4.7.1 did not occur

Packaging requirements

1, unless installed in the device (such as the installation of mobile phones, cameras, walkie-talkie, notebook computers, etc.), the battery and the original battery must be packaged separately to prevent short circuit, and packed in a solid package.
2, unless installed in the device, if each package contains more than 24 primary batteries or 12 batteries, you must also meet the following requirements:
1) Each package must be marked with a description of the lithium batteries and packaging should be taken to break the special measures.
2) Each ticket must have a random document to explain the special measures to be taken when the lithium ion battery is contained in the package and the package is damaged.
3) Each package must withstand a drop test of 1.2 m in any orientation without damaging the battery or cell in the package, without changing the position of the cell in such a way that the cell and the cell (or the cell and the cell) Contact, no battery leakage from the package.
4) Unless the lithium battery is installed in the equipment, the gross weight of each package should not exceed 30kg.

Conditions limit

Delivered lithium batteries and lithium batteries can be shipped as non-limiting items (non-hazardous) if all of the following conditions are met. If any one of the following conditions is not met, the UN3090 or UN3091 Dangerous Goods Receipt Requirements should be operated
(A), the limit of lithium content
1, for lithium metal or lithium alloy primary batteries, lithium content shall not exceed 1g; for lithium-ion batteries lithium equivalent content does not exceed 1.5g.
Note: The original battery is also called the battery core.
2, for lithium metal or lithium alloy battery, the total content of lithium does not exceed 2g, for lithium-ion battery lithium equivalent content does not exceed 8g.
Note: The above "lithium content" refers to the amount of metallic lithium that is present on the anode of a lithium metal or lithium alloy battery. For Lithium-ion batteries, the "lithium equivalent content" in grams is calculated by multiplying by 0.3 ampere hours of rated capacity.
For example: a cell phone lithium-ion battery rated capacity 800mah (800 mAh), then its "lithium equivalent content": 0.3X0.8 (amp hours) = 0.24 grams.
(B), in line with UN test requirements
Each type of primary battery and battery has been tested and found to comply with all requirements of Part 38.3 of the UN Handbook of Tests and Criteria for the Transport of Dangerous Goods.
