This rechargeable battery makes a great replacement or handy spare for your Ring smart security, since it works with the Video Doorbell 2, as well as the Spotlight or Stick up camera. The battery lasts up to 6 months, and when it’s running low you can just pop it on charge, and it’ll be all fuelled up in no time at all. And, you won’t need to get anyone over to fit it in the device, as it’s easy to install yourself.
