1.2 V C6000 mAh C Size Rechargeable Nickel Metal Hydride Battery for Torch, Radio

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. NiMH batteries can have two to three times the capacity of NiCd batteries of the same size, with significantly higher energy density, although much less than lithium-ion batteries.

The C size Ni-MH secondary battery ranges in capacities from 2500 mAh to 6000 mAh and measures 26 mm in diameter and 50.5 mm in height. This type of 1.2V Ni-MH battery is very common and is usually used in electric torches, multimeters, and radios.
