What to know before buying

Listing details to confirm

The battery is specified as Type B for screw-detachment models and not button-detachment models. Confirm the existing battery type and attachment on the vacuum before ordering. The listing also has inconsistent battery-count wording, including “1 AAA batteries required. (included)” despite describing a 22.2V lithium-ion vacuum pack, and separate statements about a filter and two screws versus an explicit included-components list that names only a warranty card. Check the selected listing for the actual supplied items. Claims about capacity, protection, charging and service life are manufacturer statements, not independently verified performance.

Customer feedback highlights reported battery life comparable to the original, ease of replacement and compatibility. For buyers with a confirmed Type B Dyson, those points speak to the practical appeal of a replacement pack, but they do not verify the stated 5000mAh capacity or guarantee fit with every model variant. Aggregate ratings lean positive while still including lower ratings, and do not explain the reasons for them.

Frequently asked questions

Which Dyson models does this battery claim to fit?

The listing names DC31, DC34, DC35, DC44 and DC45 models and variants. Compatibility is limited to Type B versions, so check the existing battery and attachment before ordering.

Will it fit a Dyson with a button-detachment battery?

The listing says it is for Type B screw-detachment models and not button-detachment models.

What are the stated voltage and capacity?

The product description states 22.2V and 5000mAh. These are listing specifications, not independently measured results.

What accessories are included?

The explicit included-components field names a warranty card. Product features separately claim one filter and two screws, so the accessory bundle is unclear. Check the selected listing before purchase.
