Product Specifications– AE8867220PMHRE
Specification Number: AE8867220PMHRE -FPS-Spec1 Version 1 Page 7/13
6.3.10. Cycle Life :
The cycle life shall be conducted as the following procedures：
Step 1 charge the cell with the standard charge (as of section 6.3.1);
Step 2 discharge the cell at 4850mA (0.5C) to 2.75V;
Step 3 repeat Step 1 and Step 2 for 500 times.
The capacity after 300 cycles is expected to be equal to or more than 80% of the rated
capacity. The capacity after 500 cycles is expected to be equal to or more than 60% of the rated
capacity.
6.3.11. Open Circuit Voltage: 3.6V - 4.1V as of shipment.
6.4. Mechanical Performance
6.4.1. Vibration Test 95% (min) of Rated Capacity, No Leakage
After standard charge (Section 6.3.1.), the battery is vibrated with an amplitude of 0.8mm (1.6mm
total maximum excursion) for 60 minutes in three mutually perpendicular directions. The vibration is
performed between 10Hz and 55Hz at a rate of 1Hz per minute.
After the completion of the vibration, the capacity shall be measured at a discharge current of 1940mA
(0.2C) and a cut-off voltage of 2.75V
6.5. Environmental Performance
6.5.1. Thermal Shock Test No Leakage, No Fire, No Explosion
The battery is stored at 75
o
C ±5
o
C for 48 hours, moved to a temperature of -20
o
C ±5
o
C within 5
minutes and stored for 6 hours after standard charge (Section 6.3.1.).
6.6. Safety Performance
6.6.1. Short Circuit Test No Fire, No Explosion
After standard charge (Section 6.3.1.), the battery shall be subjected to a short-circuit condition with a
wire of resistance less than50mΩfor 1 hour.
6.6.2. Overcharge Test No Fire, No Explosion
After standard charge (Section 6.3.1.), the battery shall be charged at 2C (19400mA)/10V for 2.0 hrs.
6.6.3. Thermal Exposure Test No Fire, No Explosion
After standard charge (Section 6.3.1.), the battery is placed in an oven and is heated up at a rate of
5
o
C until the temperature reaches 130
o
C. The oven shall be maintained at 130
o
C for 60 minutes.
7. Delivery Condition: about 50% charged.
