Here’s the [https://www.dyson.com/support/journey/spare-details.968670-06|manufacturer’s part information] for the battery.
Not sure if it means that it isn’t suitable for the two V7 models shown and is for the other V7 model e.g. V7 Allergy, V7 Absolute (black), V7 Animal HEPA etc, or it is the other way around. Check if there is a matching part number to the one above, on the battery pack of your particular model.
If the part number on your model’s battery pack is different to the one shown above, search online using the part number for your model to find suppliers.
