Testing method
50% battery SOC state frequency of 1 KHZ ac
resistance tester.
Discharge with the current of 0.33C until it can't
discharge, and then rest it for 1h. Charge the battery
following CC (0.33C)/CV (14.6V) mode to full capacity,
and then rest it for 1h. Repeat above process until full
charged capacity is no more than 80% of normal
value. Accumulated times is defined as cycle life.
At 25±5°C discharge the battery with the current of
0.33C to the cut-off voltage. Store the battery at
various temperatures for 2h and discharge the
battery with 0.33C to the cut-off voltage.
Charge the battery to full capacity and store it for 28
days, and then discharge it with 0.33C to the cut-off
voltage.
