LIVIASA V8 Battery Replacement: 21.6V 6000mAh Li-ion Battery Compatible with Dyson SV10 V8 Animal V8 Animal+ V8 Motorhead V8 Fluffy V8 Absolute V8 Carbon Fiber Series Cordless Vacuum Cleaner

This battery has an approximately 65 Wh capacity ( Or around 2,800 mAh, the same as the Dyson OEM battery). The nameplate lists 129 Wh and 6,000 mAh, which is a lie. This lie doesn't necessarily mean it isn't a good product, just that the sellers are fudging the truth.

The battery is a drop in replacement for the OEM battery, and to swap the batteries you just have to remove three screws, pull the original battery out, slide in the replacement battery and re-install the 3 screws, so the replacement procedure is very user friendly.

I measured it to run my Dyson V8 battery for 7min 30 sec in MAX mode, and 42min 30sec in LOW mode (without powered accessories). It takes 70 Wh of power to re-charge the battery from fully depleted (tested twice). I believe that it is equivalent in capacity to the OEM battery when new.

The real question is, how long (calendar age) will the battery last and how fast will it degrade. In my experience with other replacement dyson batteries, they degrade faster than OEM Dyson batteries (typically only lasting for one or two years), but until a few years have past, I can't talk about the lifespan of this battery.

If you want the BEST replacement battery, you should probably buy a Dyson branded battery from the Dyson store. However, they are not inexpensive, and the primary advantage of replacement batteries are their low cost. So you will have to weigh the honesty of this battery seller against the low cost of their product...
