Will This Battery Work in Your Dyson V8?
EGR’s listing names the V8 Animal, Absolute, Motorhead, Fluffy and Carbon Fiber (SV10). That does not mean it fits every machine called a V8. Dyson uses two V8 battery groups, D and E, and you find yours from the first three characters of the vacuum’s serial number. Run this quick check before you buy.
EGR’s listing does not say which Dyson battery group (D or E) this pack suits. Ask EGR to confirm your serial prefix, or compare your old pack’s screw holes, switch button and contacts with the new one before you fit it.

Is the EGR 9000mAh battery a genuine Dyson battery?
No. It is an aftermarket replacement battery sold under the EGR brand. Genuine Dyson batteries are sold by Dyson.
Is the 9000mAh capacity verified?
No. 9000mAh and 194.4Wh are the advertised ratings. We found no independent capacity test. Listings for the same product have also shown older 7000mAh wording.
Will it fit every Dyson V8?
Not necessarily. Dyson uses different V8 battery groups, identified by the first three characters of the serial number. EGR’s listing names V8 Animal, Absolute, Motorhead, Fluffy and Carbon Fiber (SV10) but does not state which group it suits. Confirm your serial prefix before buying.
How long does it run on one charge?
No tested runtime for this EGR battery is available. Dyson’s up to 40 minutes figure applies to its own V8 battery under set conditions.
How long does it take to charge?
EGR’s charge time is not verified. Dyson says a full charge of an original V8 takes up to 5 hours, but that figure is for Dyson’s own battery.
Is a charger included?
No charger appears in the box contents of the V8-1+1 listing. It lists the battery, dust cover, screwdriver, three screws, one pre-filter and one post-filter.
Does it come with a warranty?
The Amazon.ca listing’s warranty field reads “NO”. Dyson says genuine parts keep its guarantee intact, and iFixit advises contacting Dyson before replacing the battery if the vacuum may still be under warranty.
How should I dispose of the old Dyson battery?
Do not put it in household trash or recycling bins. Tape the terminals or bag the battery separately and take it to a battery collection or hazardous-waste service.
