V10 Cordless Battery Dies after 20-24 months??

Hello @szfaber.

As you can probably imagine, battery life and overall lifespan can vary greatly from one household to another. Things that can affect overall battery health and life include how the machine is used and stored, how well it’s being maintained, and even how often the filter(s) are cleaned. For that reason and all these variables, we’re not able to place a guarantee on the overall life of your battery. Having said that, batteries are replaceable, and when purchased direct via Dyson, will come with their own product guarantee. There are some rare times as well when we’ve had an owner think an issue is caused by the battery, but it could be something else (ie: charger).

Please get in touch via WhatApp so we can run you through some quick and easy troubleshooting checks: To do this, simply click on our Guides and manuals link, navigate to the ‘Contact us’ section of the page and start a WhatsApp conversation.

If you do need a replacement part, we can help you find the right one, and confirm if it’s covered by your Dyson guarantee.

Best wishes,

Hi @szfaber 

A very frustrating predicament. Battery failure is very unpredictable. Sadly it can’t be tracked back to just one cause, a combination of sources can influence the capacity, discharge and operation. It’s important to highlight this doesn’t just effect vacuum batteries but any that are rechargeable. 

@kellym mentioned a few of the most common causes and although you could have taken the utmost care, degradation can still occurs.

Overcharge, undercharge, discharge, temperature, humidity, maintenance and prolonged impact/damage are only a few examples. This isn’t something you can track back. With all these possibilities, as a standard, heavy duty battery manufacturers will only ever cover them for a 1 - 2 year duration. 

These warranty terms mean you’ll be able to obtain a replacement within this time. If this window elapses, there is no requirement for any business to provide a replacement. The only solace manufacturers can really offer for purchasing replacements or investing in new technology, is that the battery development has come a long way in such a short amount of time. In some cases, they’ve doubled or tripped their capacity and runtime.

I wouldn’t say we’ve done anything different in storing or charging our vacuum. The battery is still going strong after 4 years.

I think some batteries just fail. It’s just unlucky it’s happened to you right after the warranty expired.

Thank-you all for the comments and suggestions.  I have ordered a replacement battery and as some have said - Just bad luck with this battery.  Still a great vacuum!!
