Ring Doorbell 2 hardwired and battery life draining

I too have a Ring Doorbell 2 that decided to just not charge anymore. While mine is from Nov 2018, I find it suspicious so many people are having this problem now…even in Florida. The cold weather, while true for these batteries, does not completely hold water and it would appear Ring is using that has a convenient excuse. I mean, you already have my subscription fee, is buying a new device just a money grab?
