How do I figure out which ring doorbell version I have?

We recently bought a house that has a ring doorbell. We want to buy either the extra battery or the solar charger but not sure if we have version 1 or version 2. How do we figure out which version we have of the ring doorbell?

Hey @jennbeme. Could you take a picture of the Doorbell, preferably a front and back photo? Once we see what it looks like, this should help!
