I have put Battery in Smoke Detector but it is still giving the chirping sound? What can I do?

This can be very frustrating when the chirping sound just wouldn’t stop! Simply exercise more little patience. At times, it takes a smoke alarm about 15-20 minutes to reset and accept a new battery when just installed, before starting its normal operation. 

smoke detector stops chirping within a minute or two after the battery has been replaced. Try the fixes below to stop the chirping sound after replacing your old battery with a new one:

  • Ensure the battery has been inserted appropriately, taking note of the battery polarity (I.e., having the positive and negative terminals of the battery corresponding with the positive and negative tabs in the smoke detector).
  • In case a battery has been placed back to front, the smoke detector won’t register a new battery that has already been installed. 
  • Check if there is any corrosion on the battery terminals. In case there is, make use of some fine sandpaper (emery paper) to give them a quick clean up.
  • Is the 9-volt battery you just inserted brand new or it has been stored in a cupboard for some time now? Always try to install a fresh battery when necessary.
  • Check out the shelf life/expiry date of the battery usually imprinted by the side of the battery.
  • You can check the quality of the smoke detector’s battery as well. Most times, the cheap ‘no-name brand’ batteries have poor lasting ability compared to the popular quality brands, although it’s usually more expensive, which will usually perform better than their cheaper counterparts.take Battery out of Smoke Detector
