Quick answer: A Dyson V11 click-in battery has a quick-release button that lets the pack slide out without removing its main retaining screws. A screw-in battery is fixed to the handle assembly. These two formats are not interchangeable.
Turn the vacuum off and remove it from the charger. Look at the underside where the battery joins the handle. A prominent release mechanism indicates the click-in type; a fixed casing with retaining screws indicates the screw-in type.

Click-in versus screw-in
| Feature | Click-in | Screw-in |
|---|---|---|
| Removal | Press release and slide out | Remove retaining screws |
| Visual cue | Release button | Fixed screw points |
| Interchangeable | No | No |
Use model and part numbers as confirmation
A model code such as SV14 helps narrow the platform, but the physical mounting method is the decisive visual check. Also compare voltage, terminal layout and part references from the original pack. Never modify a connector, case or screw point to make an incorrect battery fit.

Battery-only or charger kit?
If the original charger works correctly and is undamaged, a battery-only replacement may be sufficient. A kit is useful when the charger is missing or intermittent. Charge on a ventilated surface and stop using any pack that swells, cracks, smells unusual or becomes abnormally hot.

FAQs
Can I convert one format to the other?
Do not attempt a makeshift conversion. Use the design intended for the vacuum.
Is every SV14 battery screw-in?
Model codes help, but physically verify the mounting method.
Why is the battery difficult to remove?
Check that the release is fully pressed and debris is not obstructing it. Never pry a lithium-ion pack.
