Frequently Asked Questions

How long do August smart lock batteries typically last?
August smart lock batteries typically last 6-12 months with normal use, depending on usage frequency, temperature, and battery quality. Heavy use or extreme temperatures can reduce battery life to 3-6 months.
Can I use rechargeable batteries in my August smart lock?
No, August recommends against using rechargeable batteries. Rechargeable AA batteries provide 1.2V compared to 1.5V from alkaline batteries, which can cause performance issues and shorter operating life.
Will my August lock stop working completely when batteries are low?
The August app provides low battery warnings when batteries reach 15-20%, giving you several days to weeks before complete failure. However, the lock will eventually stop responding when batteries are fully depleted.
What happens if my August lock batteries die while I'm away?
If you have an August Connect WiFi bridge, you may still receive notifications, but the lock won't respond to app commands. You'll need physical key access or to have someone replace the batteries from inside your home.
How can I monitor August smart lock battery levels?
Check battery levels regularly in the August app under device settings. The app displays percentage remaining and sends push notifications when batteries reach 20% and 15% charge levels.
