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.
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.Withstand long periods of deep discharge
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.Lower self-discharge rate than nickel-metal hydride(20% per month
vs. 30% per month)
7. 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.
8. High quality and high reliability. Nickel cadmium battery is
manufactured under very strict quality management and has excellent
quality dependence.
Brief Introduction of Ni-Cd Battery
Ni-Cd Battery is a DC power supply battery, it can be repeated more
than 500 times charge and discharge, economical and durable. Its
internal resistance is small, can quickly charge, but also for the
load to provide large current, and discharge voltage change is very
small. It is the earliest type of battery used in mobile phones,
super instruments, Emergency Lighting Products, it has good high
current discharge characteristics, strong ability of overcharge and
discharge, simple maintenance and so on.
The most fatal disadvantage of Ni-Cad Battery is that if memory is
not handled properly during charging and discharging, serious
“memory effect” will occur, which will shorten service life
greatly. Of course, we can reduce the “memory effect” by mastering
the reasonable charging and discharging method.
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
