Late last night (naturally), my battery-powered smoke detector started beeping. I got up at 3 a.m. and removed the battery so I could get some sleep, but the thing kept beeping! This makes no sense to me and has been bugging me all day. I'm going to replace the battery tonight so I can sleep, but why would it keep beeping when I had removed the power source?

Please note that this smoke detector is not hard-wired into the house, it is battery-powered.

It's made to do that, with an internal reserve power source.
Would you rather have a smoke detector that sits quietly with dead batteries?
Solution: Put in new batteries...today!

The smoke detector is most likely wired into the power of the house, and the battery is only a backup for the power running to the unit. It will beap however, either when the battery is dying, or if there is no battery in it. Take the smoke detector off the ceiling, and see if a wire is attached to it from the ceiling. Most likely, you can unplug the wire easily, which will stop the beeping.

Well, it sounds as if your smoke detector is hard-wired to the house (the battery must have been in case of power outages) and that it is in "silenced" mode. This is usually triggered by your alarm going off and you pressing the button to silence it. Once this happens, it will give a little beep every now and then to let you know that it can not be triggered (fire or no fire) in this time. The good news is that this usually only lasts for about 10 mins and then it should go back to normal assuming there is nothing to trigger it again! If it does not go back to normal after a while, check to see if there is a reset button of some sort, and if not, disconnect the power to reset it (there should be a couple of wires attached to a little plug that can simply be unplugged and plugged back in)

it beeps like that because it is connected to the wiring that goes through the house. Detectors are manufactured to have a small power conduit installed. Once you change the batteries o remove them the beep is more frequent as it is alerting you to the fact that you need to add batteries. Add them then push the test button you should be good.

Because it is a smoke detector that was put in to save your life if there should be a fire in your house. When you took the battery out you prevented it from doing its job. It was beeping to remind you that you should really put the battery back.

Some are also supplied by the mains, but that would mean it wouldn't need the battery...hmmm strange. Perhaps it has a smaller battery in it to create a beep when the larger main source battery has been removed, to annoy you and force you to replace the battery quick.

To let you know the battery is dead so you can replace it. They are designed this way so that you do not have a fire without it going off and then sue the smoke detector company for a bad part.

It's trying to warn you and let you know that it needs a new battery, so you can be safe. Interesting though, it would need some source of power to beep, maybe it has another tiny watch-type battery just in case the regular one fails.

the battery might just be a back up.
if it is linked to the security system if will beep until you put a new battery or unplug the whole unit from the system, you will see a small wire with a modular connector on it, look for that.
but relace the battery

I think smoke detectors have some sort of back up power source but I really have no idea how it works.
