O'Reilly, Auto zone, Batteries plus carry motorcycle batteries 79.00 to 296.00 depending on amps required and month life of the battery Looks like 159.99 for a duracell for the trike ... lithium batteries will be more
Check at your local Sam's Club Walmart and Kmart they all carry batteries back in there Auto section for motorcycles
Last battery I got for my deuce was from Batteries Plus.
I got mine from advance Auto parts.
