Do Dyson Cordless Vacuum Batteries Last Long?

In general, a Dyson cordless vacuum battery isn't going to last more than a few years. Although your vacuum may be in good working condition, you may need to replace its battery every three to four years.

This is pretty standard for Dyson batteries and might even be covered by the company's two-year battery warranty. Again, every vacuum will have a unique lifespan based on how often you use and charge it, but bet on about four years of use.

How Do I Know My Dyson Needs A New Battery?

Although there are a few indicators your Dyson might need a new battery, shorter vacuuming time is the most common. If your cordless vacuum is fully charged yet only working for a few minutes, this could be a sign it needs a new battery.

Your Dyson may also start to have a red flashing light or 10-12 red or blue flashing lights appear every time you turn it on, which is another sign of a failing battery.

How Do I Test My Dyson Vacuum Battery?

For anyone wanting to test their Dyson's battery, this is simple. To start:

  1. Fully charge your vacuum.
  2. Grab your phone and set its stopwatch function to 0:00.
  3. Turn your vacuum on and start your timer.
  4. Switch your Dyson to its "MAX" setting.
  5. Run your vacuum until it stops and record this time.

One thing to note, a Dyson battery should run for about six minutes on its MAX setting if it's in good health, so anything far below this may indicate you need a new battery.

How Long Should A Fully Charged Dyson Battery Last?

Typically, a fully charged Dyson battery will last around 20-30 minutes. That does not account for your vacuum's MAX setting, which will cut this time down to about five or six minutes.

This timeline might be slightly different depending on which Dyson cordless vacuum model you have, but don't expect more than 30 minutes of run-time per full charge regardless.

Dyson batteries will usually take between three and four hours to charge fully. For example, if you have a Dyson Cyclone V10 Animal vacuum, your estimated charge time will be 3.5 hours, while a V11 vacuum tends to need 4.5 hours of charging.

With that said, Dyson promises different times for each of their cordless vacuums, so we recommend checking your product's specific care instructions.

Should I Leave My Dyson On Charge All The Time?

Although it may sound weird, yes, it is a good idea to leave your Dyson charging all the time. Dyson vacuum batteries are designed for permanent charging, meaning that keeping them plugged in between uses is beneficial.

Doing this is also a good way to ensure your device is always ready for cleaning, so you might want to consider continuous charging.

Does The Blue Light Stay On While Charging Dyson?

Yes, a blue light will flash while your Dyson vacuum charges. This should continue for the entirety of your device's charging period, so don't be alarmed if yours continues to flash.

Once your Dyson reaches a fully charged battery, both of its LED lights will stay on for five seconds and then turn off. As we covered above, you can keep your vacuum on a charge, so there is no need to disconnect it once its battery is full.

What Does It Mean When My Dyson Flashes Blue 10 Times?

If your Dyson vacuum flashes blue ten times, this means it needs to be plugged in. A blue flashing light will often have to do with your device's battery, so keep an eye on it.

That said, if you notice your vacuum start to flash blue often or not run as long as usual on a full charge, it might be time to replace its battery.

How Do I Replace A Dyson Cordless Vacuum Battery?

If it's time for a new battery, replacing the one in your cordless Dyson won't be too hard. To start:

  1. Switch off your Dyson vacuum and disconnect it from its charger.
  2. Press the red release catch button twice, once for your bin and again for the cyclone.
  3. Using a screwdriver, remove the screw from the back of your Dyson's handle.
  4. Place your vacuum on a soft surface and remove the second screw from the underside of its battery.
  5. Throw away your old battery and screws.
  6. Place your new battery into the vacuum handle, ensuring it clicks into place.
  7. Secure your new battery in place using its included screws.
  8. Re-attach the bin and cyclone to your device.
  9. Fully charge your vacuum, and you're done!

Where Do I Buy A Dyson Battery?

When it comes to purchasing a new battery for your Dyson cordless vacuum, you want to shop directly through them. Dyson recommends buying replacement batteries from their website, so you know you're getting the real thing.

You can also find Dyson replacement batteries at Amazon, Walmart, and other stores/websites, although purchasing through them might affect your warranty. Buying replacements outside of Dyson might also mean you aren't getting a Dyson-made battery, which means the quality won't be the same.

How Do I Know If My Battery Is Covered Under Dyson's Warranty?

As long as your vacuum is under two years old, Dyson will usually replace the battery. Whether it's due to a factory defect or an aging device, Dyson promises to cover any costs associated with your cordless vacuum's battery for its first 24 months.

On top of that, Dyson also ensures that any part or tool that comes with your vacuum is covered for one year after purchase, which is something to note.

What Is The Best Dyson Cordless Vacuum?

Although opinions vary, Dyson's V15 Detect and V8 Absolute models have some of the best ratings among buyers. According to CNET, the Dyson V15 Detect is their favorite cordless vacuum for 2021, with the V8 Absolute model coming in as their top choice for value.

Of course, any of Dyson's cordless vacuums will be great, but if you want the best option, we would say stick with their V15 line.

Is Buying A Dyson Vacuum Worth It?

If you're on the fence about buying a Dyson vacuum, consider what you're after when it comes to cleaning. Although Dyson cordless models will make vacuuming easier than a traditional plug-in option, you could be spending upwards of $700, which isn't for everyone.

With that said, Dyson is known for its quality and attention to detail, so if that means something to you, we would say they are worth checking out.

To Wrap It Up
