Scooter batteries are usually an AGM type or gel type battery. In an electric scooter these batteries cycle up and down over and over again making battery cycle life important. A true deep cycle AGM or Gel battery is best in these applications which will usually have a number or label designating it as deep cycle such as 6-DZF-20 or Deep Cycle printed on the front. Batteries that do not have the special DZF or DZM or Deep cycle label will fail rapidly in a scooter application
