A textbook I'm reading tells me that in a battery ( which is not hooked up to anything ) maintains a potential difference ( the cell potential difference, determined entirely by the chemical's redox potentials ).

The standard cell potential for reaction ( 2 ) is-0.158 V at 298.15 K, compared to-1.229 V for the electrolysis of water ( with oxygen evolution as the anodic reaction ).

Cells using water-based electrolytes are usually limited to cell potentials less than about 2.5 volts, because the very powerful oxidizing and reducing agents that would be required to produce a higher cell potential tend to react with the water.

The standard hydrogen electrode ( SHE ) is the reference from which all standard redox potentials are determined and has been assigned an arbitrary half cell potential of 0.0 mV . However, it is fragile and impractical for routine laboratory use.

Where E cell is the cell potential measured in volts ( V ) and C trans is the cell current integrated over time and measured in coulombs ( C ); C trans can also be determined by multiplying the total number of electrons transferred ( measured in moles ) times Faraday's constant ( F ).

During stage 4 of an action potential, the inside of a cardiac muscle cell rests at " 90 mV . As the inner muscle cell potential rises towards " 60 mV, electrochemical changes begin to take place in the voltage-gated rapid sodium channels, which permit the rapid influx of sodium ions.

Here " ?G " is change in Gibbs free energy, " ?G?" is the cell potential when " Q " is equal to 1, " T " is absolute temperature ( Kelvin ), " R " is the gas constant and " Q " is reaction quotient which can be found by dividing products by reactants using only those products and reactants that are aqueous or gaseous.
