Used a 200 amp battery charger to start with.

When it comes to diagnostics a better approach is to actually look for the
fault(s) before corrective actions are taken. A helper can be very handy.
So while cranking what is the voltage at the battery, the starter, voltage
drop across the battery to starter cable, and the ground strap. Find the
drop, than you know if you really found and fixed the problem. If the drop
is the battery, than you need to know the starter current draw. A clamp on
current ammeter is the tool for that. If you pulling 300+ amps and the
starter is laboring that is most likely the problem.

Check cables & connections as well. Need to be clean & deposit free, else
excessive resistance.
