This cell also uses a zinc can for the anode and its outside casing.
The cathode post is made of manganese dioxide (MnO2). The electrolyte paste
is potassium hydroxide (KOH). The cost of the materials is generally higher
than the zinc-carbon cell but the major benefits are the longer operational
life and longer shelf life. As the cell nears its end-of-life it may start
to leak. Be cautious when working with any leaking cell because the
potassium hydroxide is caustic. This cell is not re-chargeable. This means the
chemical reaction can not be reversed by using electricity.
