Carbon-zinc batteries have long been used around the world as a simple but reliable technology. These batteries are economical to use but also provide reliable operation for our low-power devices.
They can be used for low-power devices such as flashlights, radios, wall clocks and toys.
Panasonic's carbon-zinc batteries are much less harmful to the environment, as they do not contain added mercury, cadmium and lead, which are harmful to our natural environment.
