         A variety of battery (such as the alkaline manganese batteries, lithium manganese batteries, etc.) 

UN38.3 test 
T.1 a high degree of simulation 
   Pressure ≤ 11.6kPa, temperature 20 ± 5 ℃ conditions. 
T.2 heat test 
    In 75 ± 2 ℃ and -40 ± 2 ℃ under the conditions of low temperature high-impact test, the temperature in the storage time limit ≥ 6h, high and low temperature conversion time ≤ 30min, the impact of 10 times at room temperature (20 ± 5 ℃) storage 24h, The total test time of at least a week 
T.3 vibration test 
    7Hz within 15min from 200Hz to complete a sweep back and forth on a number of sinusoidal vibration, 3h to complete three-dimensional direction of vibration 12; 
T.4 impact test 
150g, 6ms or 50g, 11ms and a half sine shock, installed in each direction 3 times, a total of 18 times; 
T.5 foreign short-circuit test 
In 55 ± 2 ℃, foreign resistance <0.1Ω short-circuit conditions, short-circuit the battery temperature until time to return to the 55 ± 2 ℃ after 1h. 


T.6 collision test 
9.1kg weight from 61 ± 2.5cm height 15.8mm have put down in the rod cells, the detection of cell surface temperature. 
T.7 charge-off test 
2 times the maximum charge current in a row and 2 times the maximum charge voltage conditions, the battery charge over 24h.
T.8 mandatory discharge test 
     12V DC power supply battery linked to the maximum discharge current mandatory discharge. 

Testing to determine eligibility criteria 

(A) in the test T.1 to T.6, there was no fire or disintegration. 
(B) the test T.1, T.2 and T.5, the effluent is not toxic, flammable or corrosive substances. 
     
(A) visual observation did not see or exhaust leakage. 
(B) not lead to weight loss than those shown in the table 38.3.4.7.1 or exhaust leakage. 
(C) in the test T.3 and T.6, the effluent is not toxic or corrosive substances. 
(A) visual observation did not see or exhaust leakage. 
(B) not lead to weight loss than those shown in the table 38.3.4.7.1 or exhaust leakage 

Packaging requirements 
1, unless the equipment installed on (for example, installed in mobile phones, cameras, walkie-talkie, laptop, etc.) 
Original batteries and battery must be individually packaged to prevent short circuits, and installed in the outer solid inside. 
2, unless the equipment installed in each package, if equipped with more than 24 or 12 of the original cell batteries, 
Must also meet the following requirements: 
1) Each package must be marked that contains lithium batteries and broken pieces of packaging to be taken special measures 
Shi. 
2) per ticket goods must be random pieces of paper to illustrate the packaging of lithium batteries and packaging with broken pieces that should be taken 
The special measures. 
3) Each package must be capable of sustaining the direction of any of the 1.2m drop test, rather than damage to the package within 
The battery or battery million, of which there is no change in the location of the battery and the battery and battery (or the original battery power 
Chi) contact with each other, there is no battery in the package from leaking. 
4) Unless the lithium batteries installed in equipment, or the gross weight of each package can not exceed 30kg. 

Conditions 
The delivery of lithium batteries and lithium batteries if all the following conditions may be in line with the non-restricted items (non-hazardous 
Goods) transport. If any of the following conditions can not be met, it should be UN3090 or UN3091 resumption of dangerous goods transport operators request 
(A), the lithium content restrictions 
1, the original lithium metal or lithium alloy batteries, lithium content of no more than 1g; for the original lithium-ion batteries when lithium 
Volume content of no more than 1.5g. 
Note: The original battery cells, also known as core to do. 
2, for lithium batteries or lithium alloy, the total lithium content of no more than 2g, for lithium-ion batteries containing lithium-equivalent 
Amount not to exceed 8g. 
Note: The above-mentioned "lithium content" means the lithium metal or lithium alloy anode of the battery with a capacity of the lithium. 
As for the lithium-ion battery, in grams of "equivalent lithium content" is calculated by multiplying 0.3 rating 
Amp-hour capacity. For example: a cell phone lithium-ion battery is rated capacity 800mah (800 mA hours), 
Then the "equivalent lithium content": 0.3 X 0.8 (ampere hours) = 0.24 grams. 
(2), in line with UN demands to test 
Each type of primary cells and batteries, have been tested to prove in line with its "transport of dangerous goods to the United Nations and Test 
Standard Handbook, "Part 3 of all the requirements of paragraph 38.3.
