However, if you’re buying one, the first thing you must learn is how to change the batteries in a wireless doorbell.

Wireless doorbells are becoming popular as they offer a lot more benefits than your traditional doorbell.

They are often cost-friendly, easy to install, environmentally friendly, and of course, smarter with volume settings, built-in cameras, and a wide range of chimes to choose from.

As these are wireless, most of these doorbells use batteries that you may need to change after a year or two, based on the use.

However, if you don’t know how to do it, don’t worry; we will explain everything in detail in this article.

How to Change the Batteries in a Wireless Doorbell

The lifespan of the battery for most doorbells varies between six months to a year.

Some can even last as long as five years, but a lot depends on the use.

As a result, you don’t need to change batteries too frequently.

In most cases, you may have to replace them once a year.

In any case, replacing batteries in wireless doorbells is a fairly easy and uncomplicated task and can be done effortlessly without professional assistance.

The good thing is, batteries that wireless doorbells use are readily available and can be procured at reasonable prices from tech stores or online.

The process of replacing the batteries is also quite similar no matter the brand and model you have.

However, it does help to identify what doorbell you have and how to replace its battery (mostly these doorbells come with an instruction guide).

Here is a list of the most common wireless doorbells and effective methods of replacing their batteries.

Replacing the Batteries on a Wireless Push Button Doorbells

These doorbells mostly use CR2032 batteries.

In push-button doorbells, the doorbell generally indicates that the battery is low on power by flashing a red light several times, depending on the model you have.

The doorbell might also beep twice after playing its melody.

These doorbells have a bracket.

The bracket is the mainboard on which the wires are placed.

The casing on top of the bracket is the push-button.

The bracket will have a release tab on its side which is used to detach the push-button from the bracket.

It is advisable, for convenience, to use a screwdriver to push down on the bracket to remove the push-button.

After removing the push-button, turn it over to reveal a round battery cover.

You can use a screwdriver or a coin to open the cover.

Place the screwdriver or coin on the indent made on the battery cover and turn it 60 degrees counterclockwise.

This will release the battery cover.

Remove the cover and the battery placed within it.

Replace the battery with a new one.

Make sure that the new battery has been placed correctly in the right orientation.

Place the cover of the battery back on and refit it.

Ensure the arrow is aligned with the open lock symbol so it can be properly closed.

Rotate it 60 degrees clockwise to close it.

Replace the push button on the bracket and lock into position.

Replacing the Batteries on a Doorbell with Halo Lights

These doorbells use LR6 (AA) – Series three and five or LR14 (AC) – Series nine batteries in most cases.

Doorbells with halo lights signal a battery that is about to run out by flashing amber light at the bottom of the halo.

The backside of the doorbell has a battery cover similar to those found in TV remotes and alarm clocks.

You can simply pull on the handle protruding out of the cover to remove the battery.

To prevent it from being damaged, slide out the cover instead of pulling on it.

Replace the batteries.

Ensure that the batteries have been correctly placed.

The flat side of the battery should be against the spring.

The uneven side should be against the springless side of the battery holder.

Place the cover back on. Push down to ensure the cover has been properly placed.

Replacing Batteries on a Doorbell Without Halo Lights

Another commonly available wireless doorbell is the one that comes without a halo light.

These doorbells indicate a battery needs to be replaced by flashing a yellow light.

Look at the side of the bell where the controls are placed.

In most models, this light is beneath the controls.

Such doorbells will have battery covers at the bottom of the doorbell.

Remove the battery cover the same way you would a doorbell with halo lights.

Replace the batteries with LR6 (AA) – Series three and five or LR14 (AC) – Series nine batteries.

Place the battery cover back on.

Replacing the Batteries on a Wireless Motion Sensor

Some smart wireless doorbells also work as motion sensors.

These motion sensors flash a red light when the batteries are about to run out.

The old battery in your wireless doorbell can be replaced by a 9V PP3 (6LR61) battery.

Rotate the motion sensor and find a catch at the lower backside.

Use a flat blade screwdriver to release the catch.

This will cause the lower half of the motion sensor to open up.

The battery will be placed inside.

Replace the battery and close the cover.

Press down firmly on the cover to ensure it is properly closed.

These are the processes for replacing batteries in some of the most popular types of wireless doorbells.

Most other wireless doorbells are variants of these and have similar methods of replacing their batteries.
