Apply 150% of the rated voltage for 1000±12 hours at the
maximum operating temperature ±3°C. Let sit for 24±2 hours at
room temperature, then measure.
The charge/discharge current is less than 50mA.
•Initial measurement
Perform a heat treatment at 150+0/–10°C for one hour and
then let sit for 24±2 hours at room temperature. Perform the
initial measurement.
•Measurement after test
Perform a heat treatment at 150+0/–10°C for one hour and
then let sit for 24±2 hours at room temperature, then measure.
