Range
Instruction：
1. Storage time should be counted from the time of Delivery；
2. Test Method & Standard: The battery is charged at ambient temperature (21~25) ℃,
with a constant current CC/CV at 0.2℃ to charge to 4.2V,and constant voltage
charging to final current to 0.02C,then the battery is discharged with CC 0.2C
to final voltage 2.75V, The discharge time is more than 5 hours.
