Where would I find my smoke alarm battery? I need to change it because its beeping every 30 seconds. How do I change it?

It's the only 9 volt battery in the back. Good luck.
Batteries are meant to be changed out every 6 months. Fire code suggestion. Take alarm off the wall, turn it around, there it is. Even if you test it and it is good, replace. Your life is not worth the $3 battery.
