products is judged to be nonconformity.
6.4.3 According to the method specified in GB/T 23365, make 6 test batteries.
3 of them are randomly selected for the inspection of first discharge specific
capacity and first charge-discharge efficiency. If the performance of 2 batteries
fails to meet the requirements of this Standard, it is allowed to take another 3
batteries for repeated tests. If there are still 2 batteries whose performance does
not meet the requirements of this Standard, the lot is deemed nonconformity.
7 Marking, packaging, transportation, storage and quality certificate
7.1 Marking
A label card shall be affixed on the outer packaging, which shall indicate.
7.2 Packaging

product shall be stored in a dry and non-corrosive environment. From the date
of production, the product has a shelf life of 2 years.
7.4 Quality certificate
Each lot of products shall be accompanied by a quality certificate, which shall
indicate.
8 Contract (or order form) content
The contract (or order form) for ordering the products listed in this Standard
shall include the following.
