How to change a smoke alarm battery

There's no point in having a smoke alarm installed in your home without it actually working. Just like a children's toy, did you know you have to change the battery in your smoke alarm?

Nowadays, it's pretty easy to find a long-lasting battery – ones made from lithium generally have a 10-year lifespan. Other models on the market may have a battery included in the alarm unit.

If your battery does need to be changed, here's what you need to do.

  • Most smoke alarms are secured to the ceiling with a basic click-into-place bracket. If that's the case, simply remove the alarm from the bracket.
  • Disconnect the old battery and replace it with the new one.
  • Attach the unit back to the bracket and before you get off the ladder, test it to make sure it's working properly. Most units will have a "test" button.

No matter what the case is, it's essential to check that your smoke alarms are working properly by testing them at least once a year.
