What are the advantages and disadvantages of NiMH batteries?

The advantages of nickel-metal hydride batteries 1. Outstanding safety performance and stability record 2. The power density is 30-40% higher than standard nickel-cadmium batteries. Allow longer operating time or reduce the size of the battery pack. Ni-MH battery systems have higher development potential. 3. High power density. 4. Green and environmental protection without adding heavy metals. 5. Concise and clear storage and logistics transportation The preconditions of logistics transportation will not be inhibited by safety supervision. 6. It is easier to remember than nickel-cadmium batteries. 7. A variety of unit sizes can be issued. 8. Standard-specified consumer structure types and unique types, such as low self-discharge, high-rate and ultra-high-rate discharge, continuous high temperature and wide temperature structure types. 9. 2VPC means that the battery pack voltage is relatively easy to change. 10. Provide a simple and clear solution for battery charging. 11. Charge a single battery without complicated PCBs. Reinstall electronic products. The defects of nickel-metal hydride batteries. 1. New organic chemical antioxidants improve self-discharge, but at the cost of lower power density. . 2. If stored under continuous high temperature, the performance will decrease. NiMH should be stored in a cool place, and the battery charge state is about forty%. 3. It is 20% more expensive than nickel-cadmium storage batteries. Ni-MH storage batteries, which are designed for high current consumption, are more expensive than general-purpose ones.
