Again, the correct battery is the 4DLT, and they're 150 bucks plus around here.
You can get by for a time with a car battery if you're not in a cold climate, but if you have winters where you have extended periods of weather well below freezing, you'll test the little batteries to the limit.... and they will die an untimely death. I spose if you can get one with a good warranty, and a supplier that doesn't question you on why the batterie keeps dying an untimely death, you'll get ahead a bit, cause there's no warranty to speak of on a 4DLT. So, if you use a block heater, and the heat start, you'll probably get away with a little battery. Personally, I'll stick to my Delco 4DLT's.... It's a pay me now or pay me later type thing.
