Dyson V10 Battery Adapters – Use Other Batteries on Your Dyson
For the Dyson V10 — the generation where Dyson put the bin and cyclone in line with the tube, and took the pack to 25.2V from the 21.6V of the V6, V7 and V8.
9 adapters run a V10 from a power tool battery. Stepping a tool pack up to 25.2V draws harder than the older machines did, so a higher-capacity battery is worth having. Check the model before ordering — the V10 fitting is its own, and a V6, V7 or V8 battery will not seat in it.

Dyson V10 questions
Which Dyson V10 models do these adapters fit?
Every adapter in this collection fits the Dyson V10 range: 285O, 285P, SV12, SV12G, SV27, SV55-AE, SV58. It does not fit the SV18.
Why do some batteries say 18V and others 20V?
They are the same class of battery, measured at two different moments. Five lithium cells in series read about 20V fresh off the charger with nothing drawing from them, and settle to about 18V once a tool is running. A brand that prints 20V is quoting the first figure and one that prints 18V is quoting the second. That is why an adapter between an "18V" platform and a "20V" platform works: there is no conversion to do.
Will this fit my other Dyson batteries?
Only Dyson V10 batteries. Dyson also sells Dyson V6, Dyson V7, Dyson V8, and those use a different socket — same brand, different rail and terminals, so they need their own adapter. Compare the sliding rail on your battery against the photos before ordering.
How do I find the right adapter on this page?
Use the selector at the top: pick the platform on the other side of the pair and it takes you straight to the one adapter that joins them. Every combination in that list is one we actually make, so if it is there, it exists.
Can I use a Dyson V10 battery on another brand’s tool?
Not with an adapter from us. Dyson V10 works as the tool side only here — we make adapters that let other brands’ batteries run Dyson V10 tools, not the reverse.
Can I charge a Dyson V10 battery through the adapter?
No. The adapter carries current from the battery to the tool and does nothing else — there is no charging circuit inside it. Keep charging Dyson V10 batteries on their usual Dyson charger.
Will an adapter damage my Dyson V10 battery or my tool?
Used with undamaged, compatible equipment it is not expected to. Dyson V10 batteries are lithium-ion with their own protection circuit built into the battery, and it keeps doing its job through the adapter. Stop when the tool noticeably slows rather than running the battery flat, and stop using the adapter if it becomes unusually hot or the contacts look damaged.
Does it work with third-party Dyson batteries?
Usually. What matters is the socket, not the badge: if the battery slides onto a Dyson V10 tool and locks the way an original does, the adapter will take it. Aftermarket batteries do vary in moulding, so if yours looks unusual send us a photo and we will check before you order.
