Dyson V8 Battery vacuum has been a solid performer for a few years, but lately, the battery has been giving out. It barely lasts 5 minutes even after a full charge, and sometimes shuts off randomly. I think it’s finally time to replace the battery. There are so many options online — some labeled as “high capacity” (5000 mAh+), others much cheaper than Dyson’s official battery. I’m not sure which one to trust.
