A nickel–metal hydride battery (NiMH or Ni–MH) is a type of rechargeable battery. The chemical reaction at the positive electrode is similar to that of the nickel–cadmium cell (NiCd), with both using nickel oxide hydroxide (NiOOH). However, the negative electrodes use a hydrogen-absorbing alloy instead of cadmium.

Primearth EV Energy Co., Ltd. (abbreviated as PEVE) is a Japanese manufacturer of prismatic nickel–metal hydride (NiMH) and lithium-ion battery packs for hybrid electric vehicles, located in Shizuoka Prefecture, Japan. PEVE's products had been solely based on NiMH until early 2011 when the company has started mass production of Li-ion battery.
But Chevron Corp. held the patent US6969567 for the NiMH multi-cell battery pack for cars [37] until its expiration on August 23, 2018. [38] This particular patent's maintenance fees for the 4th (2008) and 8th (2012) years were paid. [39] As of December 2019 the status was "2019-12-04 Application status is Expired - Fee Related".

A nickel–hydrogen battery (NiH 2 or Ni–H 2) is a rechargeable electrochemical power source based on nickel and hydrogen. [5] It differs from a nickel–metal hydride (NiMH) battery by the use of hydrogen in gaseous form, stored in a pressurized cell at up to 1200 psi (82.7 bar ) pressure. [ 6 ]
Panasonic's fourth-generation Eneloop batteries, in AA and AAA sizes Panasonic Eneloop Smart & Quick Charger BQ-CC55 Sanyo Eneloop battery charger. Eneloop (Japanese: エネループ, Hepburn: Enerūpu), stylized as eneloop, is a brand of 1.2-volt low self-discharge nickel–metal hydride (NiMH) rechargeable batteries and accessories developed by Sanyo [1] and introduced in 2005.
The nine-volt battery, or 9-volt battery, is an electric battery that supplies a nominal voltage of 9 volts. Actual voltage measures 7.2 to 9.6 volts, depending on battery chemistry. Batteries of various sizes and capacities are manufactured; a very common size is known as PP3, introduced for early transistor radios.
