The only local source that I know of, is Gruber Power Services, they are just south of Deer Valley Airport .
I think there is a 5% off if you use our R65.org code, there should be a thread in the top area of this section  .
http://www.gruberpower.com/12-volt-18-amp-hour-ah-batteryI've got this battery in all of my bikes, get 2-3 years before they succumb to the heat here .
If you do order one, when they ask you how the battery will be used, I tell them an alarm system back up power supply, they get confused if
you tell them it's for a motorcycle, they will reply, that they don't have any batteries for motorcycles !!!!
