<p>The Dyson V6 battery is a powerful lithium-ion pack, but like any rechargeable battery, it can develop issues over time. Many users notice their vacuum running for only a few minutes, shutting off suddenly, or failing to charge properly. These problems often point to battery wear after years of use. Since the V6 battery typically lasts 2–3 years, shorter run times or flashing red lights are clear signs it’s time for a replacement. Thankfully, changing the battery is simple, and with a new one installed, your Dyson V6 can feel almost like new again.</p>
