Look at a spiral cell battery, lots of empty space around the cells.
I would go with the flat plate if its no higher.
Ditto. I have an altima yellowtop(should have gone bluetop, but what can I do now). If i had done more research into the different types of AGMs, I'd have looked towards flat plate. They seem to have a little better storage capacity, and slightly better lifespan under typical use for their size/weight. Other than that, there really isn't too much difference AFAIK.
Most people I know recommend altima bluetops as a minimum, especially if winches and such are used but the flat plates typically go for more cost than the benefits warrant, here.
