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.
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
