If your Dyson vacuum cleaner has been switching off too quickly lately, there might be an issue with its battery. This frustrating problem makes it take far longer to clean your home, so it’s important to fix it – but how do you go about doing that? What is dyson vacuum battery life?
If your Dyson battery is old, there’s a chance it may need replacing. This is usually the case if you’ve had the battery for between 2 and 6 years. Few die before 2 years old, but most won’t last as long as 6. Be prepared to replace the battery on a semi-regular basis to keep your vacuum operating efficiently.
Without a good battery, your vacuum cleaner will not work well, so we’re going to use this article to explore how long Dyson batteries last, and how you can tell if your Dyson’s battery is dying.
We’ll also look at how to make a dying battery work as well as possible.
Why is My Dyson Battery Dying So Fast?
There are several possible explanations as to why your Dyson battery may be dying so fast. The age of the battery, how it is being used, how often you charge it, and environmental factors can all affect the lifespan of a rechargeable battery.
If your Dyson battery seems to be draining quickly, there are several steps you can take to extend its life. (1)
Check the age of your battery
Rechargeable batteries tend to have a lifespan of around two years before they start to lose their effectiveness and need replacing. If your battery is older than this, it may be time to look into getting a new one.
Consider how you are using your Dyson
If it is being used excessively, this could be causing the battery to drain faster than usual. Try using it in shorter bursts or reducing the number of times you use it each day. This can help preserve the battery’s charge and extend its lifespan.
Make sure that you are charging your battery properly
Overcharging or undercharging a battery can reduce its lifespan, so it is important to make sure that you are following the manufacturer’s instructions for charging your Dyson.
Environmental factors can also affect the life of a rechargeable battery
Make sure that your Dyson is stored in an environment with temperatures between 10-35 degrees Celsius, as extreme temperatures can reduce its life.

| Specifications | Dyson V8 battery | Dyson V10 battery | Dyson V11 battery | Dyson V15 battery |
| Without suction brush | 40 minutes | 60 minutes | 60 minutes | 60 minutes |
| Voltage | 22.8 V | 25.2 V | 25.2 V | 25.2 V |
| With suction brush | 25 minutes | 35 minutes | 60 minutes | 60 minutes |
| Turbo mode | 5 minutes | 7 minutes | 10 minutes | 10 minutes |
How Long Does A Dyson Vacuum Battery Last?
Generally, most Dyson batteries last for a minimum of 2 years. Dyson generally offers a 2-year guarantee on its vacuum parts, and this guarantee includes batteries. That means that yours shouldn’t fail before the 2-year mark, even with very regular use.
If it does, you should be able to get a new battery from Dyson free of charge. Simply get in touch with your proof or purchase, and get a new one shipped out so your vacuum works properly again.
Some batteries will last for as long as 6 years. In most cases, battery lifespans are affected by how much you use them, so if you don’t vacuum particularly frequently, your battery will last longer.
There are a few other factors that may affect your battery’s longevity too, and you should avoid:
- Leaving it fully charged: fully charged batteries discharge more quickly, meaning more charge cycles will be needed overall. Only charge your vacuum fully when you are about to use it.
- Keeping it at room temperature: warm batteries lose their charge faster, so try to keep your vacuum cleaner in a cool room, away from direct sunlight.
- Charging it immediately after use: allowing the battery to cool down before you charge it should help it to last better.
- Completely draining the battery: lithium-ion batteries lose capacity when you fully discharge them, and it’s much better to partially drain and refill your battery multiple times than to fully empty it.
Understanding how to look after your vacuum cleaner’s battery will help to ensure that it lasts as well as possible.
Poor care will lead to a much shorter lifespan for the battery, and will result in you having to purchase a replacement more quickly.
You may find that your battery doesn’t stay charged for long enough to vacuum a room anymore.
Here’s a quick overview of the run-time of different dyson vacuums:
| Dyson Model | Battery Run Time |
| Dyson V7 | 30-35 minutes |
| Dyson V8 | 40-45 minutes |
| Dyson V10 | 60-65 minutes |
| Dyson V11 | 60-65 minutes |
| Dyson V15 | 60-65 minutes |
How Do You Know When Dyson Battery Needs Replacing?
You will probably notice when your Dyson’s battery needs replacing, because the vacuum will no longer run for very long without multiple charges.
To test it, you should fully charge the unit, preferably overnight. This will ensure it’s testing the full capacity.
Next, switch your vacuum to “max power” and then set a stopwatch. Run the vacuum, and time how long it lasts before it stops.
Check the time against the advertised time that the vacuum should run for, and see what you’re achieving. If the vacuum only runs for around 3 minutes or so, the battery needs to be replaced.
Sometimes, other problems can cause a vacuum to cut out, such as a dirty filter or a bin that is too full – so make sure you check these too.
Before you do your test, empty the bin, and wash the filters and leave them to dry for 24 hours. They must be completely dry before you put them back in the vacuum cleaner.
You can then test your vacuum as described above to see if it is lasting well.
How Can You Extend A Dying Battery Life?
If your battery is dying but you don’t yet want to pay for dyson replacement batteries, you might be wondering how you can help it last as well as possible.
Having to stop vacuuming every 5 minutes to charge your vacuum cleaner is intensely frustrating, so what can you do to support the battery and maximize its charge?
The first thing you should do is turn the vacuum off “max power” mode if this is applicable to your device. This gives your vacuum cleaner far more cleaning power, but it’s a real energy hog.
If you’re using your vacuum on short-pile carpets, or on hard floors, you may be able to swap to the standard mode without losing too much cleaning power. This can extend your battery life considerably.
Next, keep the vacuum’s bin as empty as possible, as this will help it to run more efficiently and save a small amount of power. Every little bit adds up with one of these machines, so don’t underestimate this.
Finally, only switch the vacuum on when you reach an area that needs cleaning. Flicking the vacuum on and off so it’s really only cleaning when it absolutely must be is a key way to maximize its life.
By using this technique, you may be able to clean a medium-sized room or two, even with a dying battery. (2)
How Do You Replace A Battery?
No matter what you do, however, there will eventually come a time when your battery has to be replaced. You should search for a replacement battery online, using the make and model codes, so you can be sure you get an exact match.
You should also search for instructions on how to replace the battery; there are some instructions included below which may help.
To begin with, you may need to remove the wand. Simply press the release button firmly, and pull the wand out with your other hand. Push down on the red catch on the side of the vacuum, and when the top pops open, push the catch again and remove the bin.
You should see a small screw in the vacuum’s handle, which can be removed with a Philips screwdriver. There’s another screw under the bin.
Take this out too, and then the battery should be free. Simply lift it off, set the new dyson battery in place, and put the screws back in.
Replace the bin and the wand, and your vacuum should be ready to go again. Check it’s working as expected, and you can get back to cleaning!
What Do You Do With The Old Battery?
Unfortunately, there’s currently no scheme for collecting and recycling old batteries. You will have to check what options are available locally to make sure you dispose of the battery safely.
Many people find this frustrating, so hopefully, Dyson will begin a recycling scheme at some stage in the future.
Conclusion
You should now have an answer to how long does a Dyson battery last? It may only be 2 years if you don’t look after it well, but you will usually get about 4 to 6 years of use out of your battery. Remember not to leave it fully charged, or to completely drain its power, and it will last better.
