What are the differences between NiMH batteries and NiCAD batteries | WEIJIANG

question,“What are the differences between NiMH batteries and NiCAD batteries?”

All in all, the main difference between NiMH and NiCd is capacity, memory effect, life and environmental issues.

The capacity of NiMH is higher than that of NiCd, and the capacity is several times that of NiCd, indicating that the use of NiMH can effectively prolong the working time of the equipment.

NiCd was first used in cell phone and laptop device batteries. The disadvantage is that there will be a serious "memory effect", which can be repeated about 500 times of charge and discharge, and the lifespan is greatly shortened. Compared with NiMH, the "memory effect" has a longer life, generally more than 500 charge-discharge cycles, compared to our company's NiMH battery cycle life can reach 1200 times.

Cadmium is toxic, so NiCAD is not conducive to the protection of the ecological environment. NiMH battery is an alternative to earlier NiCAD battery, no longer use toxic cadmium, can eliminate the pollution problem caused by heavy metal elements to the environment.

Through this article, I hope to help introduce the difference between nickel-metal hydride batteries and nickel-cadmium batteries, and help you which battery suits your needs. If you have any questions, please feel free to contact us.

Shop NiCAD battery
Between the two, first outline the advantages and shortcoming of NiCd

NiCAD batteries Advantage:

NiCd cheap
Lightweight, easy to transport and store
Works at low temperatures

NiCAD batteries shortcoming:
NiCd is not as powerful as other rechargeable batteries
Self-discharge is relatively large and unstable
NiCd batteries pollute the environmen.
Nickel metal hydride (NiMH) battery
The nickel metal hydride battery was developed at the Battle-Geneva Research Center in 1967 and was successfully completed in 1987.

NiMH battery consists of nickel hydroxide positive electrode, hydrogen storage alloy negative electrode, separator paper, electrolyte, steel shell, top cover, sealing ring, etc.

Common uses: including model aircraft, medical equipment, pagers, wireless charging mobile phones, video cameras, digital cameras, electric toothbrushes, gamepad batteries and other equipment

Shop NiMH battery
NiMH advantage:
Ultra-low energy consumption, save power for a long time,Efficient conversion, no memory effect,Environmentally friendly and safe.

Compared with the nickel-metal hydride batteries in the market, our company has common advantages. The difference lies in the fact that the actual capacity is not false, the factory supply, double-layer protection, explosion-proof and anti-leakage, high-cold resistance, normal use at minus 20 degrees, and 80% electricity when leaving the factory. Ready to use

Disadvantages of NiMH:
The price is relatively expensive.

Understand the difference between NiCad and NiMH in detail
If you have any questions about NiCad and NiMH nickel-cadmium or NiMH batteries, our team can help.

We have been working in this field for nearly 30 years, and have a group of NIMH patent teams, which have relatively rich experience in answering questions about nickel-cadmium batteries and NIMH batteries.

We look forward to your reply to discuss NiMH and NiMH issues together.
