I'm in the process of replacing my battery as well. Its old and was replaced once but I have no idea if its AGM or lead acid.

Is there an easy way to know if the current battery is Lead Acid or AGM? Is Walmart the cheapest place to get a new good battery?

I am going to borrow a friend's carly app to reprogram.
