Product Description
This product is a standard D-size nickel-cadmium battery specifically designed for emergency backup power systems, available in two high-capacity specifications: 4000mAh and 5000mAh. Utilizing robust nickel-cadmium electrochemistry, the battery delivers exceptional cycle life and stable discharge performance, operating reliably in temperatures from -20℃ to 70℃.
Supporting rapid charging and deep discharge with low self-discharge rate, it maintains sufficient power even after extended standby periods, making it an ideal power solution for emergency lighting, security systems, and backup equipment.
1. Exceptional Cycle Life: Capable of over 500 charge-discharge cycles, its durability far exceeds that of ordinary batteries, significantly reducing long-term costs and replacement frequency.
2. Remarkably Stable Performance: Delivers a flat discharge voltage curve, ensuring consistent and stable power output throughout the usage cycle, preventing performance issues in devices due to voltage fluctuations.
3. Broad Operating Temperature Range: Can start up and discharge normally even in low temperatures of -20°C, while also maintaining good stability in high-temperature environments, adapting to various harsh conditions.
4. Excellent Fast-Charging & High-Rate Discharge: Supports rapid charging and stable high-rate discharge, providing robust power for devices like power tools and emergency equipment that require instant high current.
5. Superior Tolerance to Overcharge/Over-discharge: Compared to other chemistries, Ni-Cd batteries offer greater tolerance to overcharge and over-discharge, providing higher fault tolerance and reliability in backup or improper use scenarios.
6. Factory direct supply with competitive price and OEM support
