Easy ordering, didn't wait to long for delivery, battery fitted, hoover working again.

Excellent replacement, fits like a glove.Nice touch supplying a new filter too . Bought for my mothers vacuum and it's given it a new lease of life and longer usage time between charging as its a higher capacity..

Update on my purchase, excellent after purchase customer service.Contacted me regarding my issue with the battery, offered me a refund so I can repurchase another battery, very happy!! Thank you.No longer holding its charge. I followed 1st charging instructions. Only used it 4 times since replacing it. That's 4 full charges & 4 uses. Now only lasts 5 minutes if lucky!!On the original dyson battery plug in charger, the green led light flashes then goes solid when it's fully charged. For some reason with this battery the led light is solid straight away & doesn't flash.Also the official dyson plug in / charger makes a buzzing sound while charging this battery but never did with the dyson battery?

Very happy with purchase - a good replacement at a reasonable price. Well packaged, arrived on time.

What it says on tin

Cracking replacement, Bit fiddly to get the old one off, but a you-tube video helped. Charged and working well!
