Parameter
3.1
Normal capacity
3350mAh (at @0.2C discharge)
Minimum capacity
3250mAh (at @0.2C discharge)
Nominal capacity is measured by the discharge at 0.2C to 2.5V end voltage after standard fully
charged according to specification at 25ºC

st
Capacity (25ºC±2ºC, 4.2V-2.5V)
If charged and discharged at high rate and high
temperature (≥35ºC) frequently, cell cycle life will be
shorten. If charged and discharged at high temperature
(>45ºC) frequently, cell safety may be occurred.
