Very disappointed that my Power Stroke 7.3 couldn't start in 45°F with two brand new Interstate green-tops after a week below freezing. I'm lucky I had another (seriously questionable) vehicle to go buy a new battery charger since my old shitty one is >100mi away right now. I only got three ~5sec cranks before they gave out. I usually buy black-top Interstates but even their standard batteries should do better than this, shouldn't they? And the fuel filter is like 9mo old. I don't fkn know.
One of these batteries is awfully leaky lookin'. Guess it's about time I learned how to maintain/diagnose these things
