## Description

doorbell battery

Review: Great 2nd battery - Works great. Nice to have a 2nd battery so there's no downtime.
Review: A great video doorbell - I really like that you don't need a subscription and all the videos you want are saved locally. It was easy to install and the image quality is excellent. The added feature of a second camera that looks down is great for checking for packages. It connected smoothly to my Echo Show so I can see who is at the door even if my phone is not handy. It is a great value and well made, as all the products I have used from Anker. I am running with a battery since the wiring for my old doorbell went bad. So far, battery life is ok, and it is easy to recharge. I would recommend a spare battery to minimize down time.

- Easy to Install and Remove: Intuitive clasp is designed to be simple and quick to use.
