New battery, no blue light

We have several Ring doorbell cameras in our businesses, with the removable/rechargeable batteries. I have 1 that needed the battery changed, however, when I changed it, no light came on. Not the blue spinning light or the white spinning light when you press the reset button. I have tried several different batteries, so that isn’t the case. I plan on replacing the camera itself thinking that since its several years old it was at the end of its lifespan. Then this week, at another business location, I have a different and much newer camera (same generation)with the same issue. Is there a fix for this?
