Your Dyson

Dyson V7 is model HH11, SV11 or SV37

Only know your model number?

Look on the Dyson battery, next to its serial number. It is also on the serial-number sticker on the handle, hidden under the battery. It starts with SV, HH or DC.

A V7 and a V8 look almost the same. The model number is the only sure way to tell them apart.

Estimated from battery energy, allowing for the adapter’s converter. Actual runtime depends on the power mode and the attachment fitted.

What still works on your Dyson V7

  • The trigger works as before.
  • Every power mode works, MAX included.
  • Motorised heads spin as usual, from the Motorhead to the mini motorised tool.
  • Wands, filters and the bin are unchanged.
  • The Dyson’s own battery lights stay off: check the charge on your battery’s gauge.
  • When the battery runs low, the adapter stops the vacuum to protect it.
  • The light on the side of the adapter is green when all is well and red when power runs low.

Fitting it to your Dyson V7

It only takes a few minutes, and nothing on your Dyson needs to be modified.

  1. Undo the 3 screws

    One is on the right side of the handle, the other 2 at the bottom left, between the bin and the battery. Keep them: you will need them again.

  2. Slide the Dyson battery out

    It comes straight out of the handle.

  3. Fit the adapter

    Slide it in where the battery was and put the 3 screws back.

  4. Click on your battery

    Your Metabo HPT 18V battery locks onto the adapter. Pull the trigger and clean.

Changed your mind? The original battery goes back the same way.

Metabo HPT 18V to Dyson V7: Common Questions

Which Dyson V7 models does this adapter fit?

It fits the Dyson V7 range: HH11, SV11, SV37.

Will my Dyson V7 run as long on your Metabo HPT 18V battery?

Runtime comes from the battery, not the adapter: a 5.0Ah Metabo HPT 18V battery lasts roughly twice as long as a 2.5Ah one. For this pairing use 3.0 Ah or more, because a smaller battery can sag under what a Dyson V7 draws and cut out before it is empty.

Could this damage my Metabo HPT 18V battery or my Dyson V7?

Used with undamaged, compatible equipment it is not expected to. This adapter has its own Battery Management System, which cuts power before the battery is drained too far, so it protects the battery even where the battery has no protection of its own. Stop using it if the adapter becomes unusually hot, the contacts look damaged, or the vacuum behaves oddly.

Can I charge through the adapter?

No, and it should never be attempted. The adapter carries power one way only, out to the Dyson V7: there is no charging circuit inside it, and the vacuum’s dock cannot charge through it. Always take the Metabo HPT 18V battery off the adapter and charge it on its own charger.

Does it work with third-party Metabo HPT batteries?

Usually. What matters is the socket, not the badge: if the battery slides on and locks the way an original does, the adapter takes it and the Dyson V7 runs. Aftermarket moulding does vary, so if yours looks unusual send us a photo and we will check before you order.

How much does it add to the Dyson V7?

117 g (4.1 oz), plus your battery, which sits under the handle where the original battery was. You notice the extra weight on stairs or when reaching up high; on floors it soon feels normal.

Metabo HPT 18V and Dyson V7 compatibility

It works in one direction only: Metabo HPT batteries powering your Dyson.

Compatibility can vary with the exact battery and vacuum model. Before ordering, confirm that your battery belongs to the Metabo HPT 18V platform and that your vacuum is a Dyson V7: the model number on its label tells you.

Important charging and safety information

This adapter is for powering your vacuum and nothing else. It cannot charge Metabo HPT or Dyson batteries and must never be connected to a charger or the vacuum’s dock. Always take the battery out of the adapter before charging, and charge it on the original charger made for your Metabo HPT 18V battery.
