@danceymark I’d make sure you’re looking at the correct component for your model. Capacity changes depending on the stick vac you own and the batteries aren’t interchangeable. Though, if they’re recommending this higher rate, then it should change. I wouldn’t expect they replace it without testing. 

Doublecheck the correct battery part on their web shop for batteries here - https://www.dyson.co.uk/vacuum-cleaners/accessories/replacement-battery.

I have the Dyson v7 stick model. Should a new battery give longer battery time. We only get 10mins at the moment
