Genuine Dyson replacement batteries for your cord-free machine

We take the safety of our owners seriously and want to make sure any replacement of parts and accessories is done properly. In recent weeks we have seen an increase in contact from customers who have purchased non-manufacturer approved lithium-ion battery packs for their Dyson cord-free products on sale at well-known global online retailers. In some cases these 3rd party non-manufacturer approved battery packs are poor quality and can lead to safety issues. 

As Dyson is committed to your safety and ensuring the high performance of your machine, we recommend you always use genuine Dyson parts and accessories.


Typical signs your battery needs replacing:

  • Reduced run time, when not in MAX/Boost power mode
  • Vacuum displays more than 12 flashing lights


If you require battery support or have any inquiries, please contact us at 1-877-397-6622 to see how we can help. If the above issues don't relate to you, visit our troubleshooting page below.

To help you find the right battery for your machine or identify a problem relating to another part of your vacuum, please follow our online troubleshooting guide.
