Beeping noise from smoke alarm

We have had a beeping noise from ine of the smoke alarms in the house and it was the 9v. battery. If yours is the same type of smoke alarm that we have, you may find the link above useful. It certainly helped us to figure out how to unmount the unit etc.

how to remove the cover

Spent ages pushing the screwdriver into the hole at the top, and pushing and turning all to no avail. Then instead of pushing the screwdriver right in, I just pushed it in a little and then up and back towards myself and the top fell off. Great. Job done. I hope this helps.

I doubt this will be a rechargeable battery, usually it's a standard 9v PP3.

If it's a mains-powered detector you'll need to unscrew it from its mounting plate (usually 1/4 turn anticlockwise), then unclip the wiring connector which usually includes the battery cover. Swap the battery, connect back up, screw on and press the button to test.

Job done.

There are 5 year,7 year and 10 year lifespan smoke alarms that have a non removable sealed battery built into them.

You throw them away when they pass whatever lifespan they have.
