Review on ELEFLY 21.6V 4.5Ah Replacement For Dyson V8 Battery, Compatible With Dyson V8 Animal V8 Absolute V8 Fluffy V8 Motorhead Cordless Stick Vacuum Cleaner by Doug Small

PSA: You need those tiny screwdrivers, before you even attempt this (otherwise, install was a straight pain.) Once installed, holyyyyyy - the Dyson works better than it did from the factory! Battery definitely has a strong wattage and so, the vac has better suction & performance. Only had about 1 week, so I can’t speak to it’s longevity yet.
