What size converter charger should I get?
Our vintage travel trailer doesn't currently have one, but it came with a marine battery that's rated at 85 Amp/hours. The smallest converter chargers I'm seeing are 35 amp. Is this small enough?

What I understand that you are saying is that by taking a 12v battery and connecting it in parallel with another 12v battery that because of differences in the two (even if they are the same battery model) will only produce approximately 1.5x capacity instead of 2x that would be expected?
I tried to explain it once. Let's try again.
Intitially you will get very close to 2X the capacity but as the batteries age, their relative capacity will change and the total will creep down.....because of what I stated before.
How long it takes for that to happen probably depends on luck more than anything.
I don't know of any better way to explain it. If the two produce different voltages, they will be "fighting" each other.
