    If the battery need be stored for a long time, the voltage should be 13.2V(50%SOC), and stored in the condition as storage proposal. It need at least one charge & discharge cycle every six months

    3. Test Conditions

    3.1 Standard Test Conditions

    3.1.1 Unless otherwise specified, all performance tests is required conducted at temperature 25℃±2℃, Humidity less than 45%~75%RH.

    3.1.3 Unless otherwise specified, the tested product is required unused within two month after outgoing.

    3.2 Standard Charge Mode

    "Standard Charge" means at 25±2℃ charge to limit voltage with 0.33C constant current, then charge with constant voltage until current less than 0.02ItA.

    3.3 Quick Charge Mode

    " Quick Charge" means at 25±2℃ charge to limit voltage with 0.5 C constant current, then charge with constant voltage until current less than 0.02ItA.

    3.4 Standard Discharge Mode

    "Standard Discharge" means at 25±2℃ discharge to the cut-off voltage with 0.33C current.

    3.5 Quick Discharge Mode

    "Quick Discharge" means discharge to the cut-off voltage with 0.5C current.
