How do you get your smoke detector to stop chirping after replacing the battery?

How do you get your smoke detector to stop chirping after replacing the battery?  I have tried to hold down the reset button but the chirping continues.

How old is the unit?
CO detectors will chirp at end of life.
I have to ask this stupid question but did you replace it with a new battery?  Smoke detector that I have will chirp when the battery is low until it's dead.

Hi Paul,  

I replaced it with brand new battery and I hit the reset button yet still chirping.
I think what Paul meant was if you checked with a voltmeter or batter checker to ensure that it has enough juice or not defective.  It's a worth a shot.  Do you have another smoke detector in the house that's not chirping and with working battery?  You can try swapping the batteries.

It is at end of life. 10 years is MAX for a detector and then (where I live) the building and residential codes require replacement.

Replace it and get a new one. It will work correctly.

Nowadays, most smoke detectors are hard-wired to the electricity in your house. The battery is only a backup for if the power is out.

The chirping is likely because the battery went low and now the detector is in an 'error' mode. One way to clear this would be to actually turn off the power to the detector (circuit breaker), remove the battery to the detector, and then hold down the reset button on the detector. This is basically a hard-reset.

If the chirping continues after this process, then you will need to replace it without a doubt.
