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.

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.

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.
