Dyson V10 Battery Adapters – Use Other Batteries on Your Dyson

Every adapter in this collection fits the Dyson V10 range: SV12, SV12G, SV27, SV58. It does not fit the 285O, 285P, SV18, SV55-A, SV55-AE, V10 Konical.

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.

Only the Dyson V10. The Dyson V6, Dyson V7, Dyson V8 use a different battery socket, so each one needs its own adapter. Check your model number against the list at the top before ordering.

Start with your Dyson's model number: type it in the box at the top, or find it in the lists there, to land on the right generation. Then pick the battery you already own. Every adapter on the page is one we make.

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.

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.

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.

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.
