My ring doorbell is a little over a year old and battery is draining very fast so needs to be replaced. Ring says it is out of warranty and solution is to buy a new ring doorbell for $180. Not a good solution in my opinion. I just spent another $50 for the solar panel option (which is only compatible with the first generation ring doorbell) and this does not help so now I have $230 into this doorbell. If anyone knows where a replacement aftermarket battery can be purchased, I would appreciate this info.
