The Ultimate Guide to Battery Voltage – LiTime-US

So, when a battery is not connected to a circuit, it can still maintain a voltage across its terminals, but no current will flow until a complete circuit is formed by connecting the positive and negative terminals of the battery with a conductor, such as a wire. Once the circuit is complete, current will flow from the battery through the circuit.
