Which gives longer runtime, the Fanshara or the Dinosoo?

On paper the Fanshara, at a stated 7000 mAh versus the Dinosoo's stated 6000 mAh. Treat that with caution: the Dinosoo spec sheet also lists 2800 mAh, so its real capacity is unclear.

Is the Dinosoo worth $4 more than the Fanshara?

If you want a one-year warranty and UL certification, yes. If you only care about capacity per dollar, the Fanshara is the better buy.

Will either battery fit my Dyson V8 Absolute?

Both list the V8 Absolute as compatible and use the original charger. The Fanshara also lists Fluffy, Motorhead and SV10.

Neither maker publishes a cycle life. The Dinosoo backs its pack with a 12-month warranty; the Fanshara states none, so the Dinosoo is the safer bet on longevity.

Do these void my Dyson warranty?

Using a third-party battery can affect Dyson's coverage on the vacuum. Dyson's own warranty does not apply to either pack.
