I’ve been using my Dyson V8 for a while now, but lately, the suction and runtime have dropped a lot. I’m pretty sure it’s time for a new battery. I came across the Dyson V8 Battery available B, and it looks like a decent deal — but I wanted to ask before ordering. Has anyone here tried the Dyson from USA Bat? Additionally, any feedback on the charging time or compatibility with the standard Dyson charger would be greatly appreciated. I’d appreciate your honest reviews before I decide to buy.
