Anwser: If you use your POV, every day, you should charge it every night. (In this article, POV or power operated vehicle, refers to motorized scooters and power wheelchairs.) The next morning when you wake up, unplug it from the wall and unplug it from the vehicle and it will be ready for a full day of use. If you don’t use the POV much, charge it at least every other week.
