7.5 Cycle Life
Charge cells per 7.1.2. Rest 15 minutes. Discharge per 7.2.3. Rest 15 minutes before recharge. The
test environmental temperature is 25℃±2℃. A cycle is defined as one charge and one discharge.
Discharge capacity shall be measured after 500 cycles.
Discharge capacity (500th Cycle) ≥70% of 1st Cycle Capacity
7.6 Storage Characteristics
7.6.1 After charge as per 7.1.1, store the testing cells at 25℃±2 ℃ for 28 days. Then discharge as per
7.2.2. Then the same cell is fully charged as per 7.1.1 again and discharged a second time and
measured as per 7.2.2.
The recovery discharge capacity（2
nd
discharge capacity ）≥90% of initial capacity.
7.6.2 After charge as per 7.1.1, store the testing cells at 55℃±2 ℃ for 7 days. Then discharge as per
7.2.2. Then the same cell is fully charged as per 7.1.1 again and discharged a second time and
measured as per 7.2.2.
The recovery discharge capacity（2
nd
discharge capacity ）≥90% of initial capacity.
7.7 Temperature Characteristics
Cells shall be charged per 7.1.1 and discharged per 7.2.3. Cells , fully charged, shall be stored for 3
hours at the test temperature .The capacity of a cell at each temperature shall be compared to the
capacity achieved at 25℃ and the percentage shall be calculated. Each cell shall meet or exceed the
requirements of Table 2.

8 SAFETY
8.1 External Short-circuiting Test at 25℃±2℃
Cell fully charged per 7.1.1, is to be short circuited by connecting the positive (+) and negative (-)
terminals with a total external resistance of 80±20mohm. Stop the test when the cell voltage falls to
below 0.1V and the cell case temperature has returned to a value within 10 ºC of the original testing
temperature.
Criteria: No Fire, No Explosion
8.2 Overcharge Test
Cell fully discharged per 7.2.1, is to be overcharged with 3C to 4.2V while tapering the charge current.
Monitoring change of cell temperature during testing. The charge duration is 7 hours. Stop the test when
cell temperature decays to room temperature.
Criteria: No Fire, No Explosion
