Discharging: -20°C ~60°C

Storage (At 50% SOC and specified temp,
recoverable capacity in % vs time )

-10ºC~25ºC

(12 months ≥85% )

-10ºC ~45ºC

(6 months ≥85% )

-10ºC~55ºC

(1 month ≥90% )

20±5ºC is the recommended storage temperature

Visual Inspection

There should not be any remarkable scratches, cracks,
bolts, cauterization, deformations, swelling, leakage
and so on the surface of the cell.
