Many of the AGM batteries are good. I want to give an example of why I would recommend Odyssey batteries.
Recently I let someone borrow my carb to check against theirs. When I got it back I put it back on and turned the power of my car on to fill the bowl. I got distracted and left the power on for a week. My digital dial board comes on with the main power. When I figured out over a week later that the power was still on I checked and the battery showed just under 6 volts.
I fully expected that I had killed it and would have to be buying a new one. This one is just over a year old. I looked at their website and they have a procedure to bring their batteries back from as low as 4 volts. I spent a couple days slowly working it back to fully charged and once I got it back it sat for 24 hours at 12.98 volts. I raced with it a week later and it is working fine.
Maybe this isn't unique to this brand but the flat plate AGM design I believe to be the best design. The one I had before this one lasted 8 years and was working fine in my car when I pulled it out just because I didn't want to have any problems. It is still working great as the tongue battery for my trailer. Sorry for the long winded reply.

^^^^^ I have this same Odyssey PC1500DT that Curtis listed in my sbc 13/1. Mines 5 years old now and never been out of the car over winter. Just charge it 1x midway through the down season. Great battery but it is heavy at 49 lbs.
