IMPORTANT: Confirm your Dyson vacuum model number before you order (found on the data plate or data label at the back or bottom of the vacuum itself usually near a barcode and the Dyson name). THIS LARGER BATTERY MAY NOT FIT YOUR WALL DOCK: This high capacity battery provides up to 2 times the runtime per charge compared to the original standard Dyson battery and so it has a thicker/taller base (see image and dimensions listed below the image). If you find it too large for your wall dock, simply plug the wall adapter (charger) from your wall power outlet directly into the battery.
