Fanshara Replacement Battery for Dyson V8 vs Dinosoo Replacement Dyson V7 Battery

These are not interchangeable: the Fanshara fits Dyson V8 vacuums and the Dinosoo fits V7 vacuums, so the model you own decides it. Both are 7000 mAh, 21.6V lithium-ion packs, well above the original Dyson capacity, which means longer run time per charge. The Fanshara has far more owner feedback (111 ratings at 4.4) and cites Sony cells and CE certification; the Dinosoo rates slightly higher (4.6) but on only 28 ratings, and it ships as a kit with accessories. Buy the one that matches your vacuum; there is no real quality gap to justify switching models.

• Choose the Fanshara if you own a Dyson V8 (Animal, Absolute, Fluffy, Motorhead or SV10) and want a tested, CE-certified replacement with a large base of owner reviews behind it.
• Choose the Dinosoo if you own a Dyson V7 (Animal, Absolute, Fluffy, Motorhead, Trigger, Car+Boat or Mattress) and want a 7000 mAh pack that comes with fitting accessories.
