To make your Dyson V6 battery last longer, let it cool down before charging, especially after long use. Don’t leave it plugged in all the time once it’s fully charged. Use the vacuum in normal mode when you don’t need max suction, as max mode drains the battery faster. Store the vacuum and battery in a cool, dry place, away from direct sunlight or heat. If you won’t use it for a while, charge the battery to about 40-50% before storing. These small habits help keep the battery healthy and give you more years of use.
