Product performance:

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.

2. 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.

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. Lower self-discharge rate than nickel-metal hydride(20% per month vs. 30% per month). The rate and intensity at which it happens is influenced by the environment. Colder temperatures are generally better, since the cold slows down the chemical reaction, thereby reducing any unwanted battery self-discharge.

Something to know about Ni-Cd battery

1.What is a Ni-Cd battery?

A nickel-cadmium battery (Ni-Cd or Ni-Cad) is a rechargeable battery used in portable computers, rigs, video cameras, and other small battery-powered devices that require uniform discharge. Ni-Cds use electrodes made from nickel oxide hydroxide, cadmium metal, and potassium hydroxide alkaline electrolyte.

2.Ni-Cd Battery Pack
Two or more Ni-Cd battery cells combined to form a battery pack. Because they are typically similar in size to primary cells (non-rechargeable batteries), Ni-Cds may have lower terminal voltages and smaller ampere-hour capacities. However, unlike primary cells, Ni-Cds provide a nearly constant terminal voltage during discharge, which can result in an almost undetectably low charge. During discharge, Ni-Cds convert chemical energy into electrical energy. During charging, Ni-Cds convert electrical energy back into chemical energy.

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
