What is a Ni MH battery?

1. Low-temperature NiMH Batteries

Low-temperature NiMH batteries offer superior charge and discharge performance and longevity compared to other batteries in low-temperature environments. Therefore, they are often used in electronic devices operating in low-temperature environments. 

2. High-rate NiMH Batteries

High-rate NiMH batteries support discharge currents several times or even dozens of times higher, offering high-power, stable discharge capabilities. Therefore, they are often used in applications requiring high current discharge at a certain voltage level. 

3. Wide-Temperature NiMH Batteries

Wide-temperature NiMH batteries can operate in temperatures ranging from -40°C to 80°C. They are particularly suitable for use in harsh environments where high current discharge is not required. For example, the battery used in the vehicle's T-BOX is a wide-temperature NiMH battery. This battery offers excellent performance and can operate normally in harsh environments. The reason for such stringent battery performance requirements is that the vehicle's T-BOX functions as a vital device, much like an airplane's black box. It automatically sends a distress signal after a vehicle accident, allowing rescuers to quickly locate the accident site and maximize the effectiveness of the rescue effort. 

4. Conventional NiMH Batteries

Conventional NiMH batteries are commonly found in consumer electronics, such as AAA 7 and AA5 batteries, and are often used in remote controls and similar products.
