Advantages of Ni-Cd battery:
 

1. Ni-Cd battery has high charge and discharge efficiency and good safety performance at high temperature and has long service life under condition of long term floating charge, which makes it very suitable for emergency lighting application.In the case of high current discharge, nickel cadmium battery has low internal resistance and high voltage discharge characteristics, so it is widely used.

2. Working temperature for Ni-Cd battery could be up to 55 degree, and even up to 70 degree, and expected service life could be up to 4 to 5 years.

3. A wide range of applications. The capacity of nickel cadmium battery ranges from 100mah to 7000mah. There are four types commonly used: standard type, consumer type, high temperature type and high current discharge type, which can be applied to any wireless device.

4. More charge/discharge cycles than other rechargeable batteries to extend battery life

5. Higher energy density, lighter and more compact than lead-acid batteries Ni-Cd is preferred when size and weight are critical factors, such as in aircraft
6. Wide range temperature adaptability.Ordinary nickel cadmium batteries can be used in high or low temperature environment. High temperature batteries can be used at temperatures of 70 degrees Celsius or higher.

7. Reliable safety valve. The safety valve provides maintenance free function. Nickel cadmium battery can be used freely in the process of charge discharge or storage. Due to the special material used in the sealing ring and the effect of sealant, the leakage phenomenon of Ni Cd battery is rare.

8. A wide range of applications. The capacity of nickel cadmium battery ranges from 100mah to 7000mah. 

Ni-Cd Battery Cell Performance:

1. Ni-Cd Cell Charge Curve At 0.1C For 16h At 55 Degree

2. Ni-Cd Cell Discharge Curve At 0.25C At 55 Degree

3. Ni-Cd Cell Charge Efficiency At Different Temperature

4. Ni-Cd Cell Capacity Change At Permanent Charge At 55 Degree (0.05C Floating)

5. Ni-Cd Cell Cycle Life Curve
