At 4 AM this morning I learned there was a smoke alarm in my office. Also that the beep it makes when the battery is dead is loud as fuck. Loud enough to wake me from a dead sleep in another room.

It's always at 3-4am. Every fucking time

That's because battery voltage drops with temperature, and most houses are coldest around that time.

It had always been so with me. First time it was 1sm, second was 4am.

I had it go off recently, but it was about 7:30am! I was surprised.

That's the right amount of loudness, considering its purpose. Hope you were able to replace the battery with a minimum of misery.

I suppose that's a good point. I definitely would prefer that to burning to death. I just wish the dead battery noise could be set at a different volume to the "wake the fuck up, you're about to die!" noise.
