Introduction

For weeks, I’ve been putting the 21.6V 3000mAh Replacement Battery for Dyson V7 (model number: DYS-V7 Li-ion) through its paces. This isn’t an original Dyson battery, but a third-party replacement promising similar performance at a more affordable price. My goal was to determine if it lived up to the hype and provided a viable alternative to the often expensive OEM option. This review dives deep into the battery’s performance, features, and overall value.

Features

The DYS-V7 Li-ion battery boasts a 3000mAh capacity, promising extended cleaning time compared to a worn-out original. The grey color matches the aesthetic of the Dyson V7 series. While it’s advertised as being compatible with various V7 models (Mattres, Animal, Motorhead, Fluffy, Extra, Trigger), I tested it specifically with my Dyson V7 Animal and found the fit to be snug and secure. The build quality feels solid, although it’s noticeably lighter than the original battery. It’s also marketed as using eco-friendly materials, a plus in my book.

Performance

In terms of performance, the DYS-V7 Li-ion exceeded my expectations. I was able to achieve a consistent runtime that comfortably matched – and sometimes even surpassed – what I got from my original Dyson battery when it was new. My typical cleaning session, which previously would drain my old battery close to its limit, now consistently leaves this replacement with a significant charge remaining. I tested this across various floor types and with different suction settings. The power delivery seemed consistent, with no noticeable drop-off in suction even towards the end of a long cleaning session. The battery also charged quickly, easily matching the charging times advertised.

Pros & Cons

Pros: Excellent runtime, compatible with multiple V7 models, reasonably priced, fast charging, solid build quality.

Cons: Not an original Dyson product (which might concern some users), slightly lighter build than original (though not necessarily a negative).

Final Verdict

The DYS-V7 Li-ion replacement battery is a compelling alternative to buying a new original Dyson battery. While it’s not the same as an original, it offers remarkable value. The prolonged runtime, compatibility, and solid construction make this a worthwhile purchase for anyone looking to revitalize their Dyson V7 vacuum cleaner without breaking the bank. I wholeheartedly recommend it.
