JUNWOOD Upgraded 10.0Ah 21.6V Dyson V7 Battery Replacement (225403/229687)

Powerful replacement battery for Dyson V7 handheld vacuums

Meet JUNWOOD’s upgraded 10.0Ah replacement designed for the Dyson V7 family. Built with high-quality 21700 Li‑ion cells and a 21.6V pack, this battery aims to deliver longer run times and steadier performance across cleaning sessions. While it won’t alter the core design of your vacuum, it offers the potential for more consistent suction power as you work through stairs, upholstery, or pet hair with less frequent recharging.

The V7 ecosystem includes several popular models, and this battery is crafted to be compatible with many of them. If you own a V7 Slim, Trigger, Animal, Motorhead, Fluffy, Absolute, or SV11 variants (including the 225403 and 229687 codes), you may find this replacement a convenient upgrade. It is not intended for V6, V8, or V10 cordless vacuums, so please verify your model before swapping.
