5.3 Cycle life

5.4 Capacity retention

The charger supplies 1C constant current until battery
voltage reaches 4.2V then be changed at constant
voltage of 4.2V while tapering the charge current to less
than or equal to 0.01 C. Charging time is 3.0 hours in all. Within 1 hour after fully charged, discharged at 0.2C
continuously down to 2.75V. Within 1 hour after fully charged, discharge at 1C
continuously down to 2.75V.
A battery unit shall be repeated 300 charge/discharge
cycles, charged at CC-CV (0.5 C - 4.2V) for 3. 0 hours,
discharged at 0.5C continuously down to 2.75V Cut-off
Voltage. Measure discharge capacity.
HYB guarantee that the residual capacity of 2 cells in
series without circuitry is over than 80% after 300 cycles.
(Capacity testing after 300 cycles will be performed under
condition of 0.5C charging and 0.2C discharging)

After fully charged, stored for 28 days at 20
°C, then for 1
hour between 20
°C to 25°C and continuously discharge
at 1C to 2.75V.

Minimun Capacity
The minimum capacity is in the specifications table. The term refers to the capacity when the charged cells are
discharged to the cut-off voltage for 5 hours at 20
°C±5°C. Typical Capacity
Typical capacity refers to the median value of the capacity when a battery cell is discharged to the cut-off voltage
with the current of 0.2 C at 20
°C±5°C. Limit Charge Voltage
Charged cells with constant current to reach a voltage value, then keep the voltage constant and continue to charge
them. The voltage is referred to as limited charge voltage. The value is 4.2V. Cut-off Voltage
Cut-off Voltage Refers to the end voltage when a battery cell is discharged to reach. The value is 2.75V.

7.1 Short Circuit




7.2 Over charge

The battery cell is to be short-circuited by connecting
the positive and negative terminals of the battery with
an external load of less than 100 m until the surface
temperature decrease 10 degree from the highest
point.
The battery cell charged completely will be charged
continuously for 8hrs with the external power supply of
the limit voltage of 4.6V and the current of 3A.

The battery cell shall be no
fire, somke or explosion.



The battery cell shall be no
fire, smoke or explosion.

7.4 Crush







7.5 Impact




7.6 Heating

After complete charge, the battery cell will be
discharged to end voltage. Then connect with
external load of 30 discharge for 24hrs.

A charged battery cell is to be crushed between two
flat surfaces. The force for the crushing is to be
applied by a hydraulic ram with a 1.25 inch (32mm)
diameter piston. The crushing is to be continued
until a pressure reading of 17.2Mpa is reached on
the hydraulic ram, applied force of 13kN.Once the
maximum pressure has been obtained it is to be
released.
Drop a 10kg hammer from a height of 1m onto the
cell that is placed on a flat surface. (The largest
surface of the battery cell shall be perpendicular to
the flat surface.)

Place the battery cell in an oven. The temperature
of the oven is to be raised at a rate of 5±2/min
to a temperature of 150±2, and remain for
10min at that temperature.
The battery cell shall not
rupture, smoke, catch fire,
vent or leak.

The battery cell shall not
rupture or catch fire.






Deformation of the battery cell
is allowed, but there shall be
no fire or explosion.


The battery cell shall be no fire
