yep, a car battery is only for immediate power to start an engine. that's why it's rated in CCA's, cold cranking amps.
deep cycle batteries are made to provide steady power over longer periods of times. that's why their plates are thicker and why they're rated in RC, Reserve Capacity or AH, Amp Hours.
deep cycle tend to cost more because they have more lead in them.
You were doing fine until the more lead part. Two 53lb batteries have the same amount of lead.
The CCA/starting one will have more but thinner plates and the AH deep cycle one will have fewer but thicker plates.
You will ruin the CCA one faster by using it for AH and the AH one by using it for CCA.
RC is intended to inform but I have no idea how to use it. CCA and AH is all you need.
