Toshiba Heavy Duty batteries use manganese dioxide for the positive active material, zinc for the negative active material, neutral salt solutions such as zinc chloride ammonium chloride for electrolyte. These materials are the same as those of the Super Heavy Duty, with slight difference in formula or components.
The Heavy Duty series batteries, like the Super Heavy Duty series, are suitable for a wide range of applications. They are particularly suited for slightly heavy duty to light duty applications such as flashlights, radio cassette recorders, and clocks.
A unique sealing structure assures excellent shelf life and resistance to leakage over a long period of time.
