Batteries
TT new to me. Two batteries, dated '08, one is 75 amps, one is 675 amps. Its been awhile to have dealt with this. Should the amps be matched or is it like I have one battery? Both are deep cycle, 24dc...

Those above are right. From the numbers you gave I'd suspect they are both group 24s. If they are both still alive after 7 years someone has been lavishing them with TLC. Certainly beyond the end of normal lifespan.
Golf Cart Deep cycle batteries have the same footprint as group 24 batteries but are a couple of inches taller and MUCH heavier--about 66 pounds each. GCs are much more robust and will supply about 50% more Amp-hours, 220 to 240 depending on the manufacturer. (Or perhaps depending on their claims) They will also stand up to deep discharging much better.
