Free QuoteBoth scenarios are potentially hazardous. In the first case, the internal resistance in the battery will probably reduce the current sufficiently to prevent damage to the motor, but the battery may be damaged. In the second case, the internal battery resistance will not reduce the motor current sufficiently tp prevent damage to the motor.

Free QuoteIn summary, a battery may display voltage without delivering current due to high internal resistance, sulfation, or physical damage. Addressing these issues requires regular maintenance, timely charging, and monitoring operating conditions. What Are the Common Causes of Voltage Without Current in a Battery?
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.
Yes, a battery can have voltage but no current. This happens in an open circuit. Here, the battery shows voltage, but no load is connected to draw current. Voltage measures the potential difference, while current indicates the flow of electric charge. Thus, a voltage source can exist without current under these conditions.
Internal resistance can increase due to aging, temperature, or damage. A high internal resistance indicates that the battery is not able to deliver current effectively, despite having voltage. Inspect for Corrosion: Inspecting connectors and terminal points for corrosion is vital.
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.
High current leads to increased temperature, leading to increased parasitic internal discharge, which leads to further temperature increase. Batteries store chemical energy. They have a finite amount of it. if you use that energy faster (all other things being equal that is what "higher current" means) then the capacity will be reduced faster.
