Guide Current flow in batteries?
The easiest way to think of it is this: Current will only ever flow in a loop, even in very complex circuits you can always break it down into loops of current, if there is no path for current to return to its source, there will be no current flow. In your battery example, there is no return current path so no current will flow.

6 Frequently Asked Questions about “Can the battery produce low current ”
Why does a battery have no current?
No Current Flow: A battery may have voltage but not deliver current due to internal resistance or damage. High resistance can prevent current from flowing even if a voltage exists. No Load: If no electrical device is connected, the current remains at zero. A battery can still show voltage as long as it has not been drained or damaged.
Why do batteries have a low amperage?
It's the opposition within the battery to the flow of current. As batteries age or undergo multiple charge-discharge cycles, their internal resistance increases. This increase can lead to a situation where, despite showing adequate voltage, the battery can't deliver enough current, resulting in no effective amperage.
What happens if a battery fails to produce current?
When a battery shows voltage but fails to produce current, it means that while it can generate an electrical potential, the flow of electricity is restricted. This lack of current flow could stem from damaged cells or poor connections, preventing the battery from delivering its stored energy.
Does a battery have a voltage vs current?
Key Takeaways Voltage vs. Current: Voltage can be present in a battery without significant current (amps). Battery Health Indicators: Voltage alone is not a reliable indicator of a battery's ability to deliver power. Internal Resistance: High internal resistance can lead to a situation where a battery shows voltage but no current.
Why does a battery display voltage without current?
In summary, a battery may display voltage without delivering current due to high internal resistance, sulfation, or physical damage.
