I’ve had my Dyson V7 for a few years and recently noticed the battery doesn’t hold a charge like it used to. After just a few minutes of vacuuming, it shuts off—even after a full charge. Time to replace the Dyson V7 battery, but I’m not sure which route to take. I’ve seen both official Dyson replacements and a bunch of third-party options online. Some have great reviews, but I’m a little hesitant when it comes to battery safety and performance.
