It is non-rechargeable and has a short shelf life due to the acidic paste. The mercury button cell produces a voltage of 1.3V‚ which remains fairly constant until the end of its life. Although it produces a lower voltage than the dry cell‚ the button cell can handle greater drain rates without a rapid drop in output voltage and has
