Frequently asked questions

Which vacuum models is this battery listed for?

The listing describes compatibility with Dyson V7 variants and SV11, including Animal, Fluffy, Motorhead and Trigger models. It excludes V6, V8 and SV07. Check your vacuum’s exact model before ordering.

How long is the claimed runtime?

The listing claims approximately 30–40 minutes compared with 20 minutes for the original battery. It does not specify the operating mode or provide a battery capacity, so treat this as an unqualified listing claim.

Does the battery have a charge display?

The listing claims a display for remaining charge. The title calls it LCD, while the feature text calls it LED, so confirm the display specification if that distinction matters.

What should I check before fitting it?

The manufacturer says to use it only with a V7 vacuum in good condition. Inspect the battery contacts and avoid fitting it to a unit with damaged, scorched or water-affected contacts. Let a hot battery cool for 15 to 20 minutes before charging.
