Has anyone bought a new battery for a Dyson handheld that is not a Dyson battery? Our Dyson is just over two years old, not covered by warranty and the battery is crap. I get one room done and then that’s it, has to go on charge for bloody hours. So am I faced with buying a new battery, but won’t pay Dyson prices or just forget it and get a new handheld. Anyone got any experience of replacing the Dyson battery with a another brand?
