When an existing V7 battery needs replacing, matching the vacuum’s model series and filter connection helps identify the right fit. This BOTKK battery is made for the Dyson V7 SV11 series, with compatibility across several V7 vacuum versions. Check the model number on the back of the original battery to confirm that your vacuum uses SV11.

Which Dyson V7 vacuums does this battery fit?

It fits V7 SV11 vacuums, including V7 Animal, V7 Motorhead, V7 Fluffy, V7 Trigger, V7 HEPA, V7 Car+boat, V7 Absolute, V7 Mattress and V7 Allergy models. The compatible reference numbers are 225403, 229687 and 286121, as well as SV11. The battery is for the SV11 series only; it does not fit Dyson Advanced SV25 or SV37 vacuums. Find the model number on the back of your original battery before choosing.

• Designed for Dyson V7 SV11 replacement.
• Not compatible with Advanced SV25 or SV37 models.

What battery specifications and charging features does it have?

The BOTKK replacement uses a 10Ah (10,000mAh), 21.6V battery with six cells. It has no memory effect, so it can be charged and discharged as needed without capacity reduction. More than 2400 hours of testing is intended to support steady power and long service life; this testing is not a runtime guarantee.

• Model designation: V7 SV11.
• Safety testing references FCC, RoHS and CE standards.

Does the filter connection affect V7 fit?

The battery’s post-filter connection is twist-on, while the two pre-filters are compatible with all V7 vacuum cleaner series. If your post-filter is push-on, a V7 filter adapter is needed for that filter setup. Check the connection type on your vacuum when assessing filter fit.

• Twist-on post-filter type.
• Two pre-filters are compatible across V7 series.
• A V7 filter adapter is required for a push-on post-filter setup.

This replacement is suited to owners of a Dyson V7 SV11 vacuum who want a battery matched to that series and its listed V7 versions. It is not intended for Advanced SV25 or SV37 vacuums, and filter connection type matters when using a push-on post-filter. Its SV11 fit, 21.6V output and 10,000mAh capacity define the replacement it provides.
