I have two old Shark cordless handheld vacuums and these batteries fit and work well. I also bought a third vacuum cleaner of the same make and model with a factory battery. Aftermarket batteries seem to work the same as factory batteries. Two old vacuum cleaners with non-original batteries will work just as well as a new vacuum cleaner with the factory battery.
