The Dyson DC16 Root 6 is a handheld vacuum that provides approximately six minutes of continuous cleaning between battery charges. Typically, a person removes the lithium-ion battery (part number 912433-03) to charge it in the wall-mounted battery charger, replace it if defective or spent, or when repairing the unit or replacing other parts. The battery has a simple slide-button release lock. As a result, you should have no problem removing the DC16 battery within a few seconds of sliding the button.
