Facts On Smoke Detectors

Before we learn on how to replace a smoke detector battery, it’s important to know that smoke detectors are available in two types. There is the battery and hardwired smoke detectors.

As the name has it, battery smoke detectors are the types that operate on batteries alone. On the other hand, hardwires smoke detectors use electricity to operate.

However, these type also relies on batteries for backup. Although used as a backup, hard-wired smoke detector’s batteries also run out of power just like others.

Therefore, both battery-operated and hard-wired smoke detectors use batteries that need to be replaced on schedule.

How To Replace Smoke Detector Battery

Smoke detectors are available in different types and models. Not that different models of smoke detectors have different ways of replacing the batteries.

Below is the most common process on how to replace smoke detector battery.

1) Set your security system

Before replacing your smoke detector battery, you should first set your smoke detector security system to hold, disregard or set.

This again depends with the type and model of your smoke detector. Since most detectors have mobile apps, adjusting the system is so easy and quick.

2) Turn off the circuit

Taking safety measures is equally important. Therefore, if your smoke detector is hard-wired, you should turn off electrical power to avert electrical shock.

3) Dismount your smoke detector

Once you switch off the electricity, time is ripe to remove your detector from the base. Removing your detector from its base depends with its type and model.

While some requires a simple counterclockwise twisting, others require use of screwdrivers to open the cover.

For more directives on how to remove your detector from its base, check out its manual guide or research more on the internet.

4) Take out and replace the old battery

Once you are done with the dismounting, take out the old battery. Give your device at least 20 seconds break and insert the new batteries.

While replacing the old battery, ensure to align the polarities correctly. Close the battery cover and proceed with the next step below.

5) Reattach your smoke detector

This step entails attaching your smoke detector back to its mounting base for ready usage. At this step, you have successfully replaced your smoke detector’s battery.

Now, adjust your devices settings to turn the security system back on.
