I had trouble finding the battery as well just to help out people in the future Walmart carries value power 26r in stock for $48.88 and it is an exact size match for the OEM One. It also has about 20% more amps. It appears the battery tray in the car is slightly bigger than the stock battery size. so if you measure it out you might be able to upgrade your battery size. Here is the link to the Walmart battery. https://www.walmart.com/ip/VP-26R-Battery/47308800?wmlspartner=wlpa&selectedSellerId=0&wl13=3523&adid=22222222228039166080&wl0=&wl1=g&wl2=m&wl3=80428802209&a
