I have an electrical smoke alarm with back up battery. How do I stop it from beeping? I have already replaced the battery. It still kept on beeping. Then I removed the battery and it is still beeping.

Vacuum out the inside of the detector with a brush attachment, dust and cobwebs can make it beep. It's important also to note that smoke detectors do wear out. How old is yours?
