Commonly used rechargeable batteries
Commonly used rechargeable batteries include Lead Acid battery,Ni-Cd battery,Ni-MH battery,Li-ion battery,Li-polymer battery and LiFePO4 battery.
Ni-Cd battery(Nickel Cadmium)
Voltage: 1.2V
Cycle life: 500 times
Discharge termperature range: -20℃~60℃
Charge termperature range: 0℃~45℃
Remark: Excellent over charge performance.
Ni-MH battery(Nickel Metal Hydrid)
Voltage: 1.2V
Cycle life: 500 times
Discharge termperature range: -10℃~60℃
Charge termperature range: 10℃~45℃
Remark: Currently the AA size highest capacity is approx. 2500mAh.
Li-ion battery
Voltage: 3.7V
Cycle life: 500 times
Discharge termperature range: -20℃~60℃
Charge termperature range: 0℃~45℃
Remark: Its weight is lighter 30%~40% and its capacity is higher 60% compare with Ni-MH battery.
Li-polymer battery
