DTK 21.6V Replacement Battery for Dyson V7 SV11 — 4500mAh High-Capacity with LED Indicator

DTK Professional 21.6V SV11 Replacement for Dyson V7 is a direct-fit 4500mAh lithium-ion battery designed to restore runtime and stable power to Dyson V7 SV11 cordless vacuums.

This replacement pack is made specifically for the Dyson V7 SV11 series (Motorhead, Fluffy, Animal Pro+, Trigger, HEPA, Car+Boat, Absolute, Mattress, Allergy and referenced model numbers) and provides higher capacity than many generic V7 options. It is built from international-quality cells, tested extensively for steady output and longevity, and includes an LED indicator to show charge status. Note: it is not compatible with Dyson V6, V8, V10, V11 or the V7 Advanced/SV25/SV37 variants—check your original battery shape and model photos before ordering.

How will this DTK battery affect runtime and suction on my V7?

The 4500mAh, 21.6V battery supplies more stored energy than many aftermarket V7 replacements, which typically translates to longer cleaning sessions and more consistent motor performance. Users often notice fewer mid-clean drops in power compared with lower-capacity packs.

• Capacity: 4500mAh for extended run time
• Voltage: 21.6V to match original V7 power requirements
• Watt-hour: 97.2Wh for stable suction over the charge
• High-quality cells tested for durability and consistent output

Will this battery physically fit my vacuum and charge with the original charger?

This DTK pack is engineered as a like-for-like replacement for Dyson V7 SV11 battery housings and electrical connections. It is compatible with OEM V7 chargers and docks, so you can continue using your existing charging cable or base.

• Form factor matches Dyson V7 SV11 sockets and latches
• Designed to work with original V7 chargers and charging routines
• LED indicators on both sides to show charging status

How safe and reliable is the DTK Professional replacement?

Safety features include quality-controlled lithium-ion cells and compliance testing for major standards. DTK reports component testing and certifications to help reduce risk of overheating and to maintain stable charge/discharge behavior without memory effect.

• CE, FCC and RoHS certifications for electronics safety
• Protected cells with over-discharge and short-circuit safeguards
• LED indicators for visual charge feedback and status

What support and warranty does DTK provide if something goes wrong?

Who is this for: choose the DTK Professional 21.6V SV11 replacement if you own a Dyson V7 SV11-series model and need a higher-capacity, drop-in battery to restore runtime and consistent suction. Do not buy this pack if your vacuum is a different Dyson series (V6, V8, V10, V11) or a V7 Advanced/SV25 or SV37 variant—confirm the battery shape and model before purchasing. This option suits homeowners, pet owners, and anyone who needs longer cordless cleaning cycles without replacing chargers or vacuum components.
