I emailed Aubattery very late one night 30/05/25 and got a response the same night! They answered my questions, so I ordered the same night. The battery was delivered in 4 days and was a perfect fit. My Dyson V8 is like new again. Thank you

We bought a Dyson secondhand a few years ago and the Dyson batteries have been out of stock for ages. Got a battery from AUbattery and it works like a charm! Super easy to change over and has given our vacuum a new lease on life.

The replacement battery is excellent. Higher capacity battery compared to the one supplied by Dyson.
