I’d go with 4. That would give you ~100 aHr. of usable reserve..

They usually don’t care much on what type of core that you take to them. Just as long as its one for one and about the same size. It has more to do with recycling..

I would set the bulk charge voltage at ~14.2/14.4 volts and the float at ~13.2/13.4 volts. This is where I have my settings now. (I have 8-Rolls Surrette S-600’s) When I had 4-6 volt golf cart batteries. I carefully watched the voltage and never let them go below 11.9 volts and I got 8 yrs. usage out of them. I didn’t change the settings on my controller when I changed the batteries out..
