Review on Upgrade Your Dyson V7 Performance With Biswaye 21.6V V7 Battery Replacement - Compatible With Multiple Models by Reynaldo Guzman
Great rejuvenation for the Dyson.
The Dyson is a bit tricky to disassemble to the point where the battery can be installed. The bevel surrounding the plug is not as smooth as the OEM battery, so inserting it into the wall charger takes a bit more attention. Runs great and has given me a "brand new" dyson.
Pros
- Convenient & Upgrade Design: High capacity 4000mAh 21.6V lithium V7 replacement battery compatible with Dyson V7 series battery V7 SV11 and V7 series vacuum cleaner. (❗ Don't fit V11 vacuum or SV07 battery)
Cons
- The battery may cause permanent damage to the internal mechanics of the vacuum if not installed properly
