The voltage rating of a typical nickel-metal hydride (NiMH) battery is approximately 1.2 volts per cell. This is slightly lower than the voltage of a standard alkaline battery, which is 1.5 volts per cell. Therefore, NiMH batteries are often used as direct replacements for alkaline batteries in devices that can tolerate the slightly lower voltage. NiMH batteries are commonly available in configurations of 1.2V, 2.4V, 3.6V, and so on, depending on the number of cells connected in series. For example, a 2-cell NiMH battery pack would have a voltage rating of around 2.4 volts, and a 3-cell pack would be around 3.6 volts.
