  • Description
    Size YT4XL 50cc scooter battery for street moped style scooters and electric start ATVs & dirt bikes. This size YT4XL scooter battery is the most commonly used motor scooter battery, used on 50cc street scooters and are sometimes simply referred to as a 50cc scooter battery or 50cc ATV battery. This most common of small scooter batteries can also be found on slightly larger engine size machines with 70cc, 90cc, 110cc, & 125cc engines.

    Please see our Specification tab for detailed size and weight information.

    AGM batteries offer the following advantages over conventional batteries:

  • Sealed maintenance free design means there is no worry about checking water levels.
  • AGM technology will not leak or corrode on paint and/or chrome.
  • They have less internal resistance which offers more CCA amperage than wet batteries.
  • By nature AGM batteries are more heat and vibration resistant than conventional batteries, both which contribute to the majority of failures in scooter, ATV, & dirt bike applications.
  • Slower self discharge rate (longer shelf life) means battery can sit for extended periods of time without constant monitoring.


  • The sealed AGM battery requires very little maintenance during storage. The advanced technology eliminates the need to monitor and maintain water levels. The sealed design means much longer periods between charges when the battery is inactive.
