Replacement Battery for Dyson V11 Cordless Vacuum

A screw-in replacement battery for the Dyson V11 stick vacuum, rated 25.2 V and 4000 mAh (100 Wh). It uses the same body form, the same screw-in rail and the same contact terminal block as the original pack, so it seats and locks exactly where the factory battery did. There is nothing to unscrew beyond the pack itself — no wiring, no soldering, no disassembly.

Fit this when your V11 runs for only a few minutes, cuts out under load, or will no longer hold a charge overnight.

Specifications

Key Features

• Screw-in fit, no tools — seats on the original contact terminal block and screw-in rail. No wiring, no soldering, no disassembly.
• 4000 mAh at 25.2 V — 100 Wh of energy to restore the V11's cordless runtime.
• Original mounting geometry — the screw-in rail and contact block match the factory pack, so the vacuum balances and locks as it should.
• Rechargeable lithium-ion — charges on your existing Dyson dock or charger, exactly as the original battery does.
