The primary difference between 1.5 V and 1.2 V AAA batteries lies in their chemistry and voltage output. 1.5 V AAA batteries are typically alkaline or lithium-based, offering higher initial voltage and are commonly used in household devices. In contrast, 1.2 V AAA batteries are usually rechargeable nickel-metal hydride (NiMH) or nickel-cadmium (NiCd) batteries, which have a slightly lower voltage but are environmentally friendly due to their reusability.
