Ring doorbell 3 pro won’t turn on after new battery

I have re charged the battery of my ring doorbell 3 pro (not for the first time) and when fitting back to the doorbell it did not power up. I purchased a new battery from RING and fully charged that and when plugging this into the doorbell same thing happens. One flash of light full circle and then nothing, no response when pressing and holding either the orange button for the main button. help please
