Look at the passenger side positive battery cable near the battery terminal.
Brittle, discolored or swollen insulation on the wire on either side of the terminal is a good indication that is where the problem is.

If someone replaced the cables, did they put the grounds on the motor block or ....
No matter what charging/charged source you use it still acts the same?
Does the starter or solinoid get hot when cranking?
Does it act like the batts get a mysterious charge when left over night?
I have never seen a failed starter act like a dead battery, not that it couldn't, I'm sure someone has.
A started typically works or it don't.
Crank it till it dies without charger or jumpers, then pull the batts and have them load tested!
It sure sounds like bad batts or cables to me.
-Enjoy

How many CCA are the batteries?
850 is the minimum.
The problem could be bad cables or the starter could be about to fail.
The cable problem is not visible, the corrosion is actually inside the battery cable clamp.
I had this a while back and cut mt clamp open to see what was wrong.
When I could see the inside of the clamp, I was amazed it had ever started.
Something else to consider, all electricity in and out of the battery system passes though the passenger side battery terminal.
Three wires join in that clamp, wire to starter, wire to drivers side battery and wire to the chassis wiring AKA alternator system.
After the starter slows down feel the clamp carefully, if it is hot, your problem is probably inside the clamp.
When starter get old, heat there can cause them to loose connection and slow down before they die completely.

Well, come back and tell us if the starter made any difference.
I would give the starter about a 60% chance it is the problem.
They slow down over time and you don't realize how slow it is cranking the engine till you install a new one.
