4. Electrical Characteristics
Item Test Method Criterion
4.1 Charge
Full Charge
The charger supply 1.75A constant current until
battery voltage reaches 4.20V, then be changed at
constant voltage of 4.20V while tapering the charge
current. Charging time is 3.0 hours in all.
①Within 1hour after fully charged, discharge at
0.2C(=0.50)A continuously down to 3.0V end
voltage.
more than 300min.4.2 Capacity
②Within 1hour after fully charged, discharge at
1.0C(=2.5)A continuously down to 3.0V end
voltage.
more than 54min.
4.3 Cycle Life A battery unit shall be repeated 300
charge/discharge cycles, charged at CC-CV
(1.75A-4.20V) for 3.0hours, discharged at 2.5A to
3.0V end voltage. After 300cycles, discharging
time is measured as specified in paragraph 4.2
②.
more than 38min.
① Within 1hour after fully charged at 20 ℃ , a
battery unit is stored at 0℃. Discharge time is
measured by discharging at 2.5A continuously
down to 3.0V end voltage.
more than 35min.4.4 Temperature
②Within 1hour after fully charged at 20℃,a battery
unit is stored at 60 ℃ . Discharge time is
measured by discharging at 2.5A continuously
down to 3.0V end voltage.
more than 50min.
①After fully charged, stored for 10days at 60℃
and rested at room temperature for 1hour.
Discharge time is measured by discharging at
2.5A continuously down to 3.0V end voltage.
more than 35min.4.5 Full Charged
State Storage
Then next discharge time is measured as
specified in paragraph 4.2 ②.
more than 45min.
