What happens if the Smart Chicken Feeder fails or has run out of battery life before I could change them?

The feeder has a failsafe mode that defaults the doors to the open position if the battery level goes below 3% before you have time to change the batteries.

If you're connected to the app you will be able to keep track on the battery level and change the batteries before the level gets too low. Additionally, the LED on the front of the feeder will start flashing red when the battery goes below 10%, prompting you to change them.
