How to replace dyson v6 battery

Has your Dyson V6 battery started to underperform? Here’s how to replace the V6 battery to restore your vacuum’s run-time and suction power.

The Dyson V6 cordless vacuum has been around for a while, so it’s not surprising that many of the original batteries are starting to fail.

Lithium-ion batteries have a limited number of recharges before they need to be replaced, so this isn’t Dyson’s fault. It’s frustrating when your V6 stops performing as it once did though.

Fortunately, it’s easy to replace the battery and re-establish your Dyson V6’s original run-time.

How to Replace a Dyson V6 Battery

One of the great things about the Dyson range of cordless vacuums is that it’s easy to remove and replace the battery. This isn’t the case for all battery-powered appliances, so we applaud Dyson for giving their customers the power to swap the battery when necessary.

It’s important to take care when replacing your Dyson V6 battery though. Here’s how to do it.

Step 1: Unplug And Prepare The Vacuum

It sounds obvious, but the first step to replacing the V6 battery is to make sure the vacuum isn’t plugged into the charger.

Performing any maintenance on a vacuum while it’s plugged into the mains power supply could risk electrocution. It’s also impossible to remove the V6 battery when it’s plugged in.

Once the vacuum has been unplugged, prepare your V6 for a battery change with the following three steps:

  1. Detach the wand to make the vacuum easier to hold.
  2. Empty the dust canister using the red latch.
  3. Remove the dust canister by pressing the red latch another time.

One of the screws holding the battery in place is located at the front of the battery, so you need to remove the bin to access it.

Step 2: Remove Two Screws And The Old Battery

The Dyson V6 battery is secured using two screws. These both need to be removed before you can take out the old battery.

Start by using a Philips screwdriver to remove the screw at the back of the handle. Once that’s removed, turn the vacuum cleaner onto its side and remove the screw at the front edge of the main body of the battery.

It’s important to note that you should never disassemble the battery itself. This is very dangerous. You should only remove the two screws holding the battery in position.

You should now be able to slide the V6’s battery out of the machine. Make sure you dispose of it in a way that follows local rules and regulations for batteries.

Note: The new battery should come with two new screws. However, it’s worth keeping the old screws until you’ve checked the new battery pack contains these screws and that they fit the machine.

Step 3: Install The New Battery

Installing the new V6 battery is simply a case of sliding it into the handle. You should hear it click into place, which indicates it’s been installed correctly.

Finally, secure the battery with the two new screws. Your new battery has now been installed!

Step 4: Fully Charge The Battery Before Using It

All Dyson V6 batteries are shipped with a partial charge. Make sure you fully recharge the new battery before using your Dyson V6.

Once charged, your Dyson’s V6 battery run-time should have been restored.

Can You Replace a Dyson V6 Battery?

As you can see from the process above, it’s straightforward to replace the V6’s battery.

There’s a common misconception that Dyson cordless vacuum batteries can’t be removed, but this isn’t true. However, you can’t easily swap the Dyson V6 battery during use to extend its run-time, which is a feature of some pricier cordless vacuums.

How Do You Know If Your Dyson V6 Battery Needs To Be Replaced?

An obvious sign that you need to replace your Dyson V6 battery is if the run-time between charges has reduced. A completely dead battery may also not turn on at all.

The Dyson V6 battery also has a diagnostic light. This will flash red when there is a fault with the battery.

Note: It’s also possible for the V6’s battery to stop working due to a temporary fault. In this case, the diagnostic light will flash amber. Some common reasons for this are that the battery is either too hot or too cold.


Replacing a Dyson V6 battery is a simple process, as long as you have a new battery and the right Phillips screwdriver. Here’s an overview of the process:

  1. Switch off the vacuum.
  2. Remove the wand, empty the bin, and remove the bin using the red latch (press it twice).
  3. Unscrew the two screws holding the battery in place (one at the rear of the handle, the other on the front edge of the main body of the battery)
  4. Slide the old battery out of the handle.
  5. Slide the new battery into the handle until it clicks.
  6. Install the two provided screws to hold the battery in position.
