-SAMSUNG SDI Confidential Proprietary –
Spec. No. ICR18650-26A Version No. 1.0
7.8 Cycle Life
Each cycle is an interval between the charge (charge current 1300mA) with 2.5h or
100mA cut-off and the discharge (discharge current 1300mA) with 2.75V cut-off.
Capacity after 299cycles and plus 1 day, measured under the same condition
in 7.2
Capacity ≥ 1785mAh(70% of the capacity at 25℃)
7.9 Storage Characteristics
Capacity after storage for 30days at 25℃ from the standard charge,
measured with discharge current 1300mA with 2.75V cut-off at 25℃.
Capacity retention(after the storage) ≥ 2040mAh (80% of the capacity at 25℃)
7.10 Status of the cell as of ex-factory
The cell should be shipped in 50% charged state. In this case, OCV is from 3.65V to
3.85V.
8. Mechanical Characteristics
8.1 Drop Test
Test method: Cell(as of shipment or full charged) drop onto the oak-board
(thickness: ≥ 30mm) from 1.5m height at a random direction 6 times.
Criteria: No leakage
8.2 Vibration Test
Test method: Cell(as of shipment) is vibrated along 2 mutually
perpendicular axes with total excursion of 1.6mm and with
frequency cycling between 10Hz and 55Hz by 1Hz/min.
Criteria: No leakage
9. Safety
9.1 Overcharge Test
Test method: To charge the standard charged cell with 12V and 2.6A at 25℃
for 2.5 hours.
Criteria: No fire, and no explosion.
9.2 External Short-circuit Test
Test method: To short-circuit the standard charged cell by connecting positive and
negative terminal by less than 50mΩ wire for 3hours.
Criteria: No fire, and no explosion.
9.3 Reverse Charge Test
Test method: To charge the standard charged cell with charge current 2.6A
By –12V for 2.5 hours.
Criteria: No fire, and no explosion.
