High energy density: Energy density is more than 1.5 times that of nickel-cadmium batteries. Fast charge-discharge capability: Performs excellently in low-temperature environments.
This characteristic makes them very popular in devices with high usage frequency. No memory effect: Unlike nickel-cadmium batteries, NiMH batteries are not affected by the memory effect, allowing users to charge them at any time without waiting for a complete discharge.
Environmentally friendly: NiMH batteries do not contain toxic metals (such as cadmium), making them environmentally friendly and capable of meeting modern society’s demand for clean energy. Long cycle life: Under good charge-discharge conditions, NiMH batteries can last for more than 500 cycles, with some products reaching even 1000 cycles.
Safety and maintenance: Compared to lead-acid and nickel-cadmium batteries, NiMH batteries offer better safety. While their high energy storage characteristics pose risks in specific cases, they are generally safe for daily use. Moreover, their fully sealed design reduces maintenance frequency, further enhancing user experience.
