I don't buy this "batteries last three-five years" thing at all. My 1977 Subaru DL needed a new battery at almost 11 years. My Scion xB needed one at over 11 years. My Chrysler 300M needed one at 10 years.
And now my 2013 FR-S, at six years, has been sitting for two weeks with temperatures in the single digits. I bought a battery for it yesterday at Costco and, before I removed the battery, I thought I'd try to start the car.
It started right up. I'm returning the battery to Costco today.
Sticking with the theme of the thread, if your FR-S is your "daily driver", your battery will probably last a decade. BTW, it's at 162k miles now.
