The Zinc Air Battery
Works through a chemical process using oxygen-activated zinc and an alkaline electrolyte. The advantages of a zinc air battery include a steady delivery of voltage, good shelf life, and low cost. In addition, zinc air batteries have a high level of energy compared to their size.
Zinc air batteries produce electrochemical energy by using oxygen straight from the air. The cathode is compact yet at the same time has an almost unlimited capacity and achieves high energy densities due to the additional volume available for the zinc anode.
All of our batteries are Mercury Free for your protection.
