We give our batteries a hard time, so you can too

We give our batteries a hard time, so you can too

Tested again and again

Our batteries undergo over 2,000 hours of rigorous testing, to strike the delicate balance between energy density, power density and lifespan. The battery cells are uniquely capable – manufactured to meet our particular demands.


Safe management system

Our unique battery-saving trigger helps maximize run time – only using power when you need it. It ensures the battery does not overheat or overcharge and catch fire.

Lightweight yet powerful

Our specially-tuned batteries are engineered from lithium-ion, a powerful and lightweight material – designed with high safety, power and energy in mind.

No memory effect

Some batteries are engineered with memory effect. So if you charge a battery for a short period of time, it may only hold a small amount of charge the next. With no memory effect, Dyson batteries are adaptable to their environment, regardless of their charge cycle.

Does my Dyson 2-year warranty cover the battery?

Dyson offers a 2-year warranty on all cordless machines and parts, including the battery. If your machine is within its warranty period, we'll replace the battery for you free of charge. If you're an owner, log into My Dyson to see whether you are under warranty.

Can I buy a third party battery for my Dyson vacuum?

Dyson goes to great lengths to use the best battery technology. We perform significant safety checks and quality controls as part of the process. Only by using a genuine Dyson battery are you ensuring that your machine continues to work as intended, and that your warranty remains intact.

When should I use Boost / Max mode?

Boost and Max mode can be used for powerful, intensive bursts of spot cleaning. These modes affect the run time of your vacuum, so we encourage you to use them only on certain areas.

What shall I do with my old battery?

Dyson products are made from high grade recyclable materials. The battery should be removed from the machine before it's disposed of and recycled in accordance with local ordinances or regulations. If your battery needs replacing please call us at 844-705-4777 so that we can help you, or find a replacement online here.

How long is Dyson battery life?

Lithium-ion batteries are built to last, with energy and power packed into a small area. Over time, all batteries are subject to degradation. So if your run time has declined when the machine is not in Max / Boost mode, it might be time to buy a new battery. All our machines come with a 2-year initial warranty that includes the battery.
