What type of battery is ni-cd battery?

ni-cd battery is a nickel-cadmium type battery. The full name of ni-cd is Nickel-Cadmiun Batteries, which means nickel-cadmium battery in Chinese. It is a DC power supply battery that can be repeatedly charged and discharged more than 500 times, and is economical and durable. Nickel-cadmium batteries have small internal resistance and can discharge large currents. When they are discharged, the voltage changes very little. As a DC power supply, they are excellent quality batteries. Because they are completely sealed, there will be no electrolyte leakage. phenomenon, there is no need to replenish the electrolyte.

ni-cd battery is a nickel-cadmium type battery.

ni-cd's full name is Nickel-Cadmiun Batteries, which means nickel-cadmium battery in Chinese. It is a DC power supply battery. Nickel-cadmium batteries can be charged and discharged more than 500 times and are economical and durable. Its internal resistance is small, its internal resistance is very small, it can charge quickly, and it can provide large current to the load, and its voltage changes very little during discharge. It is a very ideal DC power supply battery.

Nickel-cadmium batteries are the earliest battery type used in mobile phones, laptops and other equipment. They have good high-current discharge characteristics, strong overcharge and discharge resistance, and simple maintenance. The most fatal disadvantage of nickel-cadmium batteries is that if they are not handled properly during the charging and discharging process, a serious "memory effect" will occur, which will greatly shorten the service life. In addition, cadmium is toxic, so nickel-cadmium batteries are not conducive to the protection of the ecological environment. Numerous shortcomings have caused nickel-cadmium batteries to be basically eliminated from the application scope of digital device batteries.

The most fatal shortcoming of nickel-cadmium batteries is that if they are not handled properly during the charging and discharging process, a serious "memory effect" will occur, greatly shortening the service life. The so-called "memory effect" means that the battery power is not completely exhausted before the battery is charged, which will cause the battery capacity to decrease over time. During the battery charging and discharging process (discharge is more obvious), some traces will be produced on the battery plates. There are small bubbles. Over time, these bubbles reduce the area of the battery plate and indirectly affect the battery capacity. Of course, we can reduce the "memory effect" by mastering reasonable charging and discharging methods. In addition, cadmium is toxic, so nickel-cadmium batteries are not conducive to the protection of the ecological environment. Numerous shortcomings have caused nickel-cadmium batteries to be basically eliminated from the application range of digital device batteries.

Basic features

• ##Nickel-cadmium batteries can be charged and discharged repeatedly for more than 500 times and are very economical;

• The internal resistance is small, and it can discharge large currents. When it is discharged, the voltage change is very small. As a DC power supply, it is an excellent quality battery;

• Because It is completely sealed, so there will be no leakage of electrolyte, and there is no need to replenish the electrolyte;

• Compared with other types of batteries, nickel-cadmium batteries can withstand Charging or discharging, the operation is simple and convenient;

• The performance will not be degraded even if left for a long time, and the original characteristics can be restored after fully charging;

• Can be used in a wide temperature range;

• Because it is made of metal containers, it is mechanically strong;

• Nickel-cadmium batteries are manufactured under very strict quality control and have very excellent quality reliability.

Main Features

• A. High lifespan
  Nickel cadmium battery can provide more than 500 times The charge and discharge cycle is almost equal to the service life of the device using this battery.

• B. Excellent discharge performance
  In the case of large current discharge, nickel-cadmium batteries have low internal resistance and high voltage discharge characteristics, so they are widely used.

• C. Long storage period
  Nickel-cadmium batteries have a long storage life and few restrictions, and can still be charged normally after long-term storage.

• D. High-rate charging performance
  Nickel-cadmium batteries can be quickly charged according to application needs, and the full charge time is only 1.2 hours.

• E. Wide range of temperature adaptability
  Ordinary nickel-cadmium batteries can be used in higher or lower temperature environments. High-temperature batteries can be used in environments with temperatures of 70 degrees Celsius or higher.

• F. Reliable safety valve
  The safety valve provides maintenance-free functionality. Nickel-cadmium batteries can be used freely during charging, discharging or storage. Because the sealing ring uses special materials and the role of the sealant, nickel-cadmium batteries rarely leak.

• G. Wide application fields
  Nickel-cadmium battery capacity ranges from 100mAh to 7000mAh. There are four categories commonly used: standard type, consumer type, high temperature type and high current discharge type, which can be applied to any wireless device.

• H. High-quality, high-reliability products have passed QS9000 quality certification.
