The Secret Feature of Makita Chargers: No App or Settings Button Needed - The Interesting Way to Switch Sounds on Makita Chargers

Makita Charger Can Actually "Sing": A Small Trick to Change the Usual "Beep"

Insert the battery of your power tool into the charger and return to work. After a while, it beeps to let you know the charging is complete.

Did you know that you can change that familiar sound?

Some of Makita's rapid chargers have a feature that allows you to switch the charging completion notification to a melody. Moreover, you don't need a special app or remote control for the settings. All you need is the battery you usually charge.

The German information site "COMPUTER BILD" introduced this feature on October 18, 2026. Even with tools you've been using for a long time, there are still unknown ways to use them. It's a topic that lets you enjoy such small discoveries.

The "Hidden Feature" is Actually a Formal Function Listed in the Manual

This story isn't about modifying products or trying operations not intended by the manufacturer.

Makita's official Japanese user manuals also include instructions on "how to switch the charging completion melody." For example, the manual for the rechargeable blower "MUB361D" explains the operations for the included chargers DC18RC and DC18RD.

In other words, it's not a secret hidden by the manufacturer but a setting that's hard to notice in everyday use.

What you expect from a charger is first and foremost to charge the battery properly. If it's working without issues, you might not often read the section about notification sounds in the manual. Moreover, it's hard to imagine just from the appearance that reinserting the battery would change the sound settings.

For DC18RC, the Key is the "About 5 Seconds" Right After Inserting

The official manual outlines the operation flow for the DC18RC as follows.

1. Insert the compatible battery into the charger connected to the power source.
2. A short confirmation sound of the currently set notification sound will play.
3. At this point, remove the battery within about 5 seconds and reinsert it.
4. The confirmation sound will change, so if you want to continue changing it, repeat the same operation.
5. When your preferred confirmation sound plays, leave the battery inserted to charge.

The setting is remembered even if you unplug the charger's power plug. There's no need to select it again each time.

Note that this procedure is based on the DC18RC instructions. If you try it with another model, you should check that model's manual. The Japanese manual for the DC18RD guides you to insert the battery into the charging port you want to change and quickly reinsert it.

Not Only Can You Choose a Tune, but There's Also a "No Completion Sound" Setting

More than having music play, some might find the silent setting practical.

The manuals for the DC18RC and DC18RD show an electronic buzzer, four types of melodies, and a silent mode. When selecting silent mode, a "beep beep" confirmation sound will play, but no sound will play when charging is complete.

What needs to be distinguished here is thatthe silence applies to the charging completion notification sound, not the overall operation sound of the charger. It's not a setting that silences the cooling fan sound.

For those who charge in a home workspace and are bothered by the sound every time it's completed, this option might be helpful. The desired notification varies depending on the environment, whether you want to be notified by sound or if a display light confirmation is sufficient.

Only Some Models Are Compatible. Check the Model Number First

The models introduced by COMPUTER BILD are the following four.

• DC18RC
• DC18RD
• DC40RA
• DC40RB

However, this doesn't mean that any Makita charger can perform the same operation.

When checking your product, confirm the model number on the unit and look for items like "charging completion melody" in that model's user manual. Even if it looks similar to a model seen in an overseas article, don't judge by appearance alone.

Also, this operation changes the notification sound. It doesn't shorten the charging time or increase battery capacity. It's important to separate the discussion of charging performance from usability settings.

On Social Media, There Are Stories Like "Even After Using It for Over 10 Years"

The surprise at this feature has been present online even before this article was published.

On the overseas forum Reddit's tool community, there's a 2020 post from a user who had been using a Makita charger for over 10 years, several times a week.

According to that person, the charger had only been making electronic sounds until then. However, one day, when inserting the battery at a work site, a melody suddenly played, and they were so surprised they stared at it for a while. Later, when another tune played, they investigated and discovered multiple melodies were set.

The post includes comments that perceive the idea of adding such a feature to a charger as "typically Japanese." Of course, this is just one user's impression and doesn't prove characteristics of Japanese products as a whole. Still, it conveys that the small playful touch embedded in practical items leaves an impression on overseas users.

In another Reddit post, in response to a question about whether chargers make sounds, replies explain the possibility of a silent setting and changing notification sounds by reinserting the battery.

These are not direct reactions to the current COMPUTER BILD article but posts that have been exchanged about the same feature for some time. While they don't represent the overall evaluation on social media, it suggests that it's a feature that easily leads to experiences of "I didn't know" or "I was puzzled by the sound change."

Even in Japanese Workspaces, "Choosing Sounds" Has Meaning

The use of this feature is not just to enjoy melodies.

For example, if you have multiple chargers lined up near your workbench. If each has a different sound, it can be a clue to determine which charger has completed. COMPUTER BILD also introduces this as an advantage in scenarios where multiple units are used.

Even in Japanese households, if you use different batteries for DIY tools or garden equipment, there will be situations where you need to pay attention to the charger's notifications.

While concentrating on work, you might want to be notified by sound. On the other hand, near rooms where family members spend time, you might want to refrain from completion sounds. The practicality of this setting lies in its ability to adapt to such close differences.

However, the way it sounds can change with surrounding work noise. Rather than relying solely on melodies, it's best to also check the status with the charger's display.

Before Replacing, Get to Know Your Usual Tools Again

This topic doesn't require purchasing new tools. If you already have a compatible charger, just knowing about the unused settings can slightly change your daily interactions.

Even notification sounds that you usually don't pay attention to become part of usability once you know you can choose them yourself.

The box you thought was "enough as long as it charges" actually had a small choice prepared. The next time you charge a battery, checking the model number and manual might reveal an unknown side of your usual tools.
