Yes, a weak hybrid battery can contribute to engine sputtering in the Prius:

Increased Strain on Gasoline Engine: If the hybrid battery is failing o r not holding charge, the gasoline engine will have to work harder to compensate, causing rough idling and sputtering.
Poor Battery Performance: A failing hybrid battery can cause the gasoline engine to turn on more frequently, which can lead to engine hesitation and sputtering due to the additional load.

Monitoring the health of the hybrid battery and replacing it when necessary can help prevent engine sputtering.
