NiCd battery, known as NiCd, are one of the most widely used battery types in consumer electronics. Their biggest feature is that they can be recharged. They can provide high discharge current. They also have a wide operating temperature range. They provide low self-discharge during storage. In addition to all these advantages, they have a disadvantage such as memory effect. Memory effect is the most limiting feature.
Ni-Cd batteries are generally preferred in backup energy systems. The most important reasons for this are their ability to store high energy in low volume and low cost. Their ability to store high energy in low volume is due to their very low internal resistance.
The average lifetime of NiCad batteries is approximately 5 years and this maintenance cost should not be forgotten for the system they are used in. Their average charge-discharge life is about 500 cycles.
Characteristics of Ni-Cd Batteries
Cell Voltage: usually 1.2V
Cut-off Voltage: usually 1.0V
Capacity: usually 600-1000mAh
What are NiCd batteries used for?
Ni-Cd batteries can provide high current instantaneously. For this reason, they are frequently used in tools that need to provide high torque instantaneously.
Nickel Cadmium batteries are frequently used in applications requiring emergency lighting due to their long storage time.
As mentioned before, Ni-Cad batteries are frequently used in RC vehicles due to their high instantaneous discharge rates.
