Wondering how long will your smoke alarm’s batteries last? The best way to answer this question is by understanding how batteries work. Smoke alarm batteries should be replaced at least once a year and more often if they are starting to show signs of wear.
The best way to tell if your smoke alarm batteries need to be replaced is to test them regularly. Most smoke alarms have a test button that you can press to see if the alarm is still working. If the alarm does not sound when the test button is pressed, then the batteries need to be replaced.
It’s also a good idea to keep spare batteries on hand so that you can replace them as soon as they start to die. This will help ensure that your smoke alarm is always working properly.
Warnings when battery needs to be changed:
Make sure to dispose of batteries properly. Do not just throw them in the trash. Batteries can leak chemicals that are harmful to the environment.
Lead-acid batteries should be recycled at a battery recycling center. Alkaline and lithium batteries can be disposed of with regular household waste.
