Product performance:
1. High life. The Ni Cd battery can provide more than 500 charge
and discharge cycles, and its service life is almost equal to the
service life of the equipment using the battery.
2. Excellent discharge performance. In the case of high current
discharge, nickel cadmium battery has low internal resistance and
high voltage discharge characteristics, so it is widely used.
3. Long storage period. The Ni Cd battery has a long storage life
and few restrictions, so it can be charged normally after long-term
storage.
4. High rate charging performance. The nickel cadmium battery can
be quickly charged according to the application needs, and the full
charge time is only 1.2 hours.
5. 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.
6. 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.
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.
Application:
1. Lighting: emergency lighting, emergency power supply, solar
lights, searchlingts, flashlights
2.Power tools: electric drills, planers, saws, power granted
3. Electronic toys: remote control car, remote control boats,
aircraft, model aircraft
4. Communication equipment: cordless phones, walkie-talkie
5. Other uses: electric shavers, massagers, electric tooth brush
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)
