The Stinger SPX925-HD Is the Go-to Battery for Harley Audio Enthusiasts and Competitors.

Big audio systems can be very demanding of a motorcycle battery. This battery has a low internal resistance. That means that it charges faster and more efficiently than a lead acid battery. The AGM design of this battery is also much more tolerant to the fast discharge cycles that big audio systems impose on a charging system.  

The Stinger SPX925HD  is the most technologically advanced battery available for the extreme demands of the motorcycle environment. When properly installed and maintained this battery will provide years of trouble free service. Stinger batteries provide power and durability like no other batteries.

This battery uses Advanced Absorbed Glass Mat technology for longer life, more power & greater reliability.

If You Don't Use or Operate Your Equipment Daily, AGM Batteries Will Hold Their Charge Better than Other Types.
