Does anyone know why the battery from the 4.4 is larger than the battery from the 3.0? Is it possible to installed a battery sized for the 4.4 in a 3.0? I'm asking because Interstate Batteries sells a battery for the 3.0i (P/N MTP-H7) for $161.95 and they offer a battery for the 4.4 (P/N MTP-93) which has a better CCA rating and is priced at $116.95. Both batteries have a Pro-Rata Warranty of 85 Months. Any help would be greatly appreciated as my current battery is pretty much done and I need to get a battery ASAP.
