How long do the batteries last?

The Birdi Smart Detector is powered by long-lasting AA batteries, which are certified to last more than 1 year. Depending on use, they can last even longer. When your batteries start to run low, we'll give you a heads-up via our app so you can avoid triggering low battery beeping.. And, if you've subscribed to our Security Concierge, we’ll send you a new set of batteries before they run out.
