T.6 collision test
       9.1kg weight from 61 ± 2.5cm height have put down in a 15.8mm rod cells, the detection surface of the battery temperature.
T.7 overcharge test
       2 times the maximum continuous charge current and two times the maximum charge voltage conditions, the battery charge 24h.
T.8 forced discharge test
       Battery linked 12V DC power, the maximum discharge current to forcibly discharge.
 
Testing to determine eligibility criteria
 
(A) in the test T.1 to T.6, no fire or disintegration.
(B) in the test T.1, T.2 and T.5, the effluent is not toxic, flammable or corrosive substances.
    
(A) visual observation not seen or exhaust leakage.
(B) not lead to weight loss than those shown in 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 not seen or exhaust leakage.
(B) not lead to weight loss than those shown in 38.3.4.7.1 or exhaust leakage
 
Packing

1, unless the installation of the device (such as installation in mobile phones, cameras, radios, laptop computers, etc.), cells and primary batteries must be packed separately to prevent short circuits and packed in strong outer packaging.
2, unless installed in equipment, each package containing more than 24 if the primary battery or batteries 12, must also meet the following requirements:
      1) Each package must be marked with a legend containing lithium batteries and special measures should be taken by the broken pieces of packaging.
      2) Each consignment must have random file will be described lithium batteries and special measures should be taken by the package damaged package is equipped.
      3) Each package must be able to withstand any of the 1.2m drop test without damage to the battery or battery element within the package, which does not change the location of the battery as well as battery and battery (or primary cells and primary batteries) each contacts, there is no leakage from the battery package.
      4) Unless the lithium battery is installed in the device, or the gross weight of each package must not exceed 30kg.
 
Conditions

Delivery of lithium batteries and lithium batteries if they meet all of the following conditions may be non-restricted items (non-dangerous goods) transport. If any of the following conditions can not be met, it should UN3090 or UN3091 dangerous goods transport operators request
(A) restrictions on lithium content
1, for primary lithium metal or lithium alloy batteries, lithium content shall not exceed 1g; for lithium-ion primary battery equivalent lithium content is not more than 1.5g.
      Note: The original batteries do the battery, also known as the core.
2, lithium metal or lithium alloy batteries, lithium content is not more than a total 2g, lithium ion battery lithium-equivalent content is not more than 8g.
     Note: The above "lithium content" means the amount of lithium metal or lithium alloy cell having an anode of metallic lithium. As for the lithium-ion battery, "lithium equivalent content" is calculated in grams multiplied by 0.3 is based on the rated capacity in ampere-hours.
             For example: a cell phone lithium-ion battery is rated capacity 800mah (800 mAh), then the "equivalent lithium content" as: 0.3 X 0.8 (ampere-hour) = 0.24 g.
(B), in line with UN testing requirements
Each type of primary cells and batteries, has been tested and found to comply with "UN Transport of Dangerous Goods Manual of Tests and Criteria" all the requirements of section 3 of paragraph 38.3.
