Canadianbatteries have some of the most extensive stocks of generic Dyson batteries in Canada. Our manufacturer produces high-quality replacements that have longer runtimes and are as reliable as the OEM batteries, the only difference being the price that we offer them. When selecting the battery that you intend to purchase, make sure that you do a visual inspection and a model match. Dyson, in its wisdom, changed the format of its batteries a few years ago but kept the same model numbers. If you have any issues finding a suitable model, drop us a line.
