What to know before buying

Compatibility is stated for Dyson V7 models only, not V6, V8, V10 or SV07. The maker advises letting a warm battery cool to room temperature before charging and cautions that MAX mode reduces battery life. Inspect the vacuum's contacts and do not use the battery with a damaged main unit.

Customer feedback highlights perceived good quality, but battery-life reports are mixed. Some customers describe long use in normal mode, while others report fast drain on power. That difference matters for buyers relying on the listing's 25–35-minute runtime claim, which is not tied to a stated operating mode.

Positive themes

Mixed feedback

Battery-life feedback varies, including reports of long normal-mode use and fast drain on power.
