Car Battery Voltage Fluctuation While Running -Solution 2024

Battery voltage keeps going up and down? When the bat t ery''s charge is low, the voltage is slightly jumped to return the charge quickly. When the charge level is high, the voltage is reduced somewhat to stop the battery from getting too charged. The voltage may go up or down if the car has a tester. This is fine. Why is my car battery voltage fluctuating? Car

Why does battery voltage slowly return to the open voltage?

This causes a drop in the terminal voltage. Active ions from electrolyte at a distance from the electrode will then diffuse from more concentrated regions to the active region but that only occurs slowly within time scales of minutes. As the concentration returns to normal the open-circuit voltage recovers.
