Work just as described. Fit nicely and work correctly in my machine.

Gives my 20+ year old Dyson an extension of its life.

Perfect and it was what I needed. Works well.

Works as advertised

I had an older Dyson model vacuum my sister left at my house when she moved to live with her daughter. She didn’t think it worked anymore as it would not charge. I didn’t use the vacuum for another 3 years when my daughter suggested we buy a new battery as she has a current Dyson and said that might be the problem. Sure enough. Bought this and now I have a working Dyson too! Used model number to order the replacement battery online from Amazon. Saved me $500+ by not having to buy a new vacuum. Holds charge perfectly now!

After only 5 months the battery voltage has dropped to a point where the Dyson vacuum will not power the power brush on the extension for carpet cleaning. Even with a fully charged battery the power brush will come on only for a few seconds and then it is shut off. This is the 3rd replacement battery I have purchased and it is by far the one with the shortest lifespan. The vacuum still works fine with a decent operating time as long I don't attach the power brush on the extension.

it works
