Nickel-Metal Hydride (NiMH)
makerA rechargeable battery type utilizing nickel oxide hydroxide and a hydrogen-absorbing alloy for its electrodes.
expanded
NiMH batteries are rechargeable energy storage units widely utilized in portable electronics and power tools, offering a higher energy density compared to nickel-cadmium (NiCd) batteries. They have practical applications in situations requiring moderate power consumption with a conventional voltage output of approximately 1.2 volts (V) per cell, which makes them suitable for consumer-level applications, reducing environmental impact compared to disposable batteries.
