How does voltage affect battery performance?

Age and the frequency of charging cycles also play a role, as batteries naturally lose voltage capacity over time due to degradation. While voltage pushes the current through a device, current measures the flow rate of electrons. Both are essential for performance, as voltage ensures the flow, and current provides the power needed by the device.
