Replacing the battery of the Dyson V6 is easy with the right tools, which I’ll share in this article. For this demo, I’ll be using the Dyson V6 Mattress, one of the many V6 options available.
Even if the V6 is no longer in production, replacement batteries are still in abundant supply.
So, it makes sense to replace the battery if the rest of the vacuum is still functional.
Can you change the battery on a Dyson V6?
Many people have the misconception that Dyson cordless vacuums are disposable. That is furthest from the truth. Yes, replacing a Dyson V6 battery with the proper tools and knowledge is possible. Just get a screwdriver set with a rubber handle, making it easier to loosen the bolts.
Replacing the battery will easily extend the life of any V6 vacuum; the great news is you’ll have a myriad of options for replacement batteries so that part of the equation isn’t a concern.
Tools you’ll need:
- Philips screwdriver: Get something with a #0x50mm and #0x60mm head or something close to that size.

Update [March 12, 2024]: I recorded this video to give you a visual aid for how these steps are done.
Steps to replace the V6 battery:
Loosening the bolts would be much easier if you could find something with a rubber handle. Avoid using something with a smooth handle because it can slip off your palm, and there’s that risk of damaging the screws on the vacuum.
Step 1: Empty the dustbin
Push the red lever below the trigger to open the trap door and empty the contents of the dust bin.
It is essential to remove the contents of the receptacle first in preparation for the next step.
Step 2: Detach the dustbin from the body
Continue holding down on the red lever to release the lock that holds the dust canister. Then, separate the container from the body.
Removing the bin will provide easy access to the second screw holding the battery right in front.
Step 3: Remove the two screws holding the battery in place.
Two screws hold the batteries—one behind the handle and another right in front of it, below the red release lever.
Bolt 1 (behind the handle)
Bolt 2 (below the release lever)
You’ll need a 0x55mm screwdriver to remove the screw behind the handle and a slightly larger 0x60mm screwdriver for the bolt in front.
Step 4: Remove the battery
After the two screws are loosened, take out the battery.
Step 5: Attach the new battery.
Attach the new battery and tighten both screws to secure it in place.
If you’re having trouble tightening both behind the handle, push the battery upward so the holes line up.
How long does a Dyson V6 battery last?
If you’re wondering how long it will run, Dyson says it will run for at least 20 minutes using non-powered tools. Based on my experience with Dyson products, their claims are pretty accurate.
For instance, the V11 Torque Drive has a claimed run time of 60 minutes, but tests reveal that it runs past the 70-minute mark. The V10 Absolute, in my tests, ran for around 61 minutes.
How many years does the Dyson battery last?
There isn’t a specific answer for service life as it depends on several factors, such as usage frequency and how you store it.
I have a Dyson V6 Mattress that has been nearly four years old, and the batteries are still working fine.
As long as you follow the best practices regarding lithium-ion battery care, the V6 batteries should easily last for four or five years without too much degradation in run time.
How do I know if my Dyson v6 battery needs replacing?
If the battery doesn’t hold a charge or it’s continuously blinking red light, it may be time to buy a new one.
Where to buy V6 replacement batteries?
There are a plethora of options available online. An excellent place to start would be online stores like Amazon and Walmart.
Since Dyson no longer manufactures the V6, it does not sell replacement batteries, but some third-party merchants do.
I would buy the highest capacity battery I can afford with a rating of 4 stars and above. There are options with as much as a 6.0 Ah battery. These will run longer than the advertised 20 minutes from the OEM battery.
If that’s too heavy, opt for the smaller, lighter 4.0 Ah batteries.
