BOTKK KB440-03H V7 Replacement Battery, 10,000mAh, 21.6V Li-ion

The 10,000mAh capacity gives this rechargeable Li-ion battery a clear role: replacing the battery in a compatible Dyson V7 cordless vacuum. Its 21.6V rating and SV11-series fit help identify the right replacement for your device.

BOTKK model KB440-03H is designed for V7 models including Animal, Motorhead, Fluffy, Trigger, HEPA, Car+Boat, Absolute, Mattress, and Allergy. It also lists battery references 225403, 229687, and 286121.

Choose a replacement battery when the vacuum itself is the part you want to keep using. The most important step is matching the vacuum’s series and original battery model before installation.

Key features

The 10,000mAh capacity and rechargeable lithium-ion design make this a replacement battery for regular use with a compatible V7 vacuum. At 21.6V, it is specified for the Dyson V7 SV11 series, with a broad range of V7 configurations named for compatibility. This lets you check the battery against your specific vacuum rather than selecting a replacement by brand name alone.

Compatibility is limited to the SV11 series. It does not fit Dyson V7 Advanced SV25 or SV37 models, so check the model information on the vacuum or original battery before choosing. A replacement is a focused alternative to replacing the entire vacuum when the goal is to swap the battery and continue using a compatible V7.

Buyers often describe the battery as straightforward to replace and report positive experiences with fit and charging. Feedback on battery life is mixed: some say it lasts longer than their previous battery, while others report that it stopped working within a few months. These are individual experiences, not a guarantee of service life.

Tips for day-to-day use

Use the battery only with a compatible Dyson V7 SV11 vacuum, and follow the vacuum’s normal charging and handling instructions. The lithium-ion battery is rechargeable, so it is intended for repeated use rather than disposal after one charge. Keep the exact series distinction in mind when shopping: the SV11 fit does not extend to the SV25 or SV37 models.

Practical tips

Before ordering, compare the model number on your original battery or vacuum with the SV11 compatibility listed here. Confirming the series is especially useful if the vacuum name includes “V7,” since the SV25 and SV37 versions are specifically excluded. You can also use the listed compatible names—such as Motorhead, Animal, Fluffy, and Trigger—as a cross-check, along with battery references 225403, 229687, or 286121 where applicable.

For a battery swap, set aside a clear workspace and refer to the vacuum’s instructions for the correct removal and installation process. Customer feedback describes the replacement as easy to install, but following the device-specific instructions helps keep the work appropriate for your vacuum. If you are choosing between a battery replacement and replacing the whole vacuum, this model is intended for the former: a compatible SV11-series V7 that you want to continue using.

Questions before you buy

Which Dyson vacuums is this battery designed for? It is specified for the Dyson V7 SV11 series, including Animal, Motorhead, Fluffy, Trigger, HEPA, Car+Boat, Absolute, Mattress, and Allergy models. It is not compatible with V7 Advanced SV25 or SV37 models.

What are the battery’s capacity and voltage? The battery is rated at 10,000mAh and 21.6V, with lithium-ion cells. It is rechargeable for repeated use with a compatible vacuum.

How do I check whether my vacuum is the right version? Look for the model number on the original battery or vacuum and confirm that it belongs to the SV11 series. Do not rely on “V7” alone, as the SV25 and SV37 versions are excluded.

Is it worth it?

For someone keeping a Dyson V7 SV11 vacuum in use, this replacement offers a clearly identified 10,000mAh, 21.6V battery and compatibility across several named V7 configurations. Matching the SV11 series is the key to making it a suitable battery swap rather than buying by the V7 name alone.
