And Dyson has legal liability if they catch fire and a name brand to uphold if they don’t meet advertised runtimes. Amazon does not.
If you want a new battery for your Dyson, buy a tool battery adapter from Amazon and buy the tool battery from your local hardware store. Same price or less and you get insane run time + a new tool battery.
This x100. The Dyson batteries are expensive and die quickly (someone mentioned their experience mitigating the failure time by waiting to put the vacuum back on the charger until after it has cooled off). Getting a Milwaukee adapter for my Dysons has worked out really well. Runtime is much better, and I have one less custom battery size to deal with in my house.
