1.5 Battery Section
1.5.1 General Specification
Description
Specification Standard and Method of
Measurement
Typical Capacity 3000mAH
Charge Voltage 4.2V
Output Voltage Typical : 3.7V Limit : 4.2V No Load Condition
Cut Off Voltage Typical : 3.0V Limit : 2.8V
Standard Charging
Method
0.5C Constant current charge to 4.2V
(+/- 0.05V), then constant voltage
4.2V charge till charge current decline
to <= 0.05C
Charging Time 3 hour (Standard Charging)
Maximum Charge
Current
1.0C
Standard Discharge
Method
Discharge current of 0.5C with 3.0V
cut-off after standard charging.
Maximum Discharge
Current
2.0C
Overcharge Current
Protection
12A
Cycle Life Typical : 80% of initial capacity
Limit : 75% of initial capacity
Continuous standard charge and discharge
for 500 cycles. The capacity is measured at
the end of 500 cycles
Capacity Retention Typical : 90% of initial capacity
Limit : 85% of initial capacity
Fully charge the battery at 23 +/-5°C, then
stored it at an ambient temperature for 60
days. Measured the capacity after 60 days
storage with 0.5C discharge at 23 +/-5°C as
retention capacity.
Continuous Charge
Test
No leakage, no visible evidence of
electrolyte loss, no explosion and no
fire.
The battery discharged at 0.5C 23 +/-5°C,
then fully charged and held at the specified
end of charge voltage for total period of 30
days.
Over Charging
Discharging
No leakage, no visible evidence of
electrolyte loss, no explosion and no
fire.
The battery fully charged at 0.5C 23 +/-5°C,
discharge the battery at constant 0.5C, until
battery circuit terminates discharge or at 0V,
then charge the battery with 0.5C until
battery circuitry terminates charge or at
4.2V. Repeat the cycle for 30 times.
Short Circuit No explosion, no fire, maximum
temperature of battery surface should
not exceed 150°C
The battery to be fully charged with
standard charging condition, and short the
positive and negative terminal with wire
resistance = 30 mOhm.
