Ring Video Doorbell comparison

Hello, I'm new to Ring and I wanted to buy a new Ring Doorbell in substitution of my old one, but I have a question. With my budget, I was thinking about getting a [Ring Video Doorbell (2nd generation)](https://www.amazon.it/dp/B09324G52L/) or the [Video Doorbell Wired](https://www.amazon.it/dp/B08LR3G17D/), which are both on offer, but I don't quite understand the difference between them. (The idea was to wire them to a **24VAC** transformer). Are they the same, except that one has an internal battery? How long does the battery last? Thanks
