My 16 Dart didn't start this morning. The last couple days it turned over a little slow in the morning. The factory battery is an H5. The local dealer doesn't carry an H5. The local parts stores say an H6 is the direct replacement. Looks like the H6 is a larger battery. Does anyone know if they are a direct replacement? I don't want to take a part store's online listing as gospel. Thanks

Some real world good info here. https://www.dodge-dart.org/threads/2-4l-gt-battery-replacement.63864/

Thanks. Looks like an H6 will fit if you remove a little plastic spacer on the battery tray.

O'Reilly's is supposed to have an H5 in stock. It's a Super Start which I've never heard of. However it looks like East Penn Manufacturing makes them. They also make Duralast batteries for Autozone and EverStart for Walmart. The Super Start is an AGM battery.

Super start is a good battery.
