slow turning

i started my 94 F-350 yesterday morning with no problem. i stopped for coffee, went to start truck and it turned barely like i had a dead battery. i've since had the battery and starter checked, no problem there, lights etc work great. still turning slow. any suggestions?

Just a few possible causes off the top of my head:

Weak battery
Weak alternator
Poor 12V connections at battery/starter/starter relay
Poor ground connections at engine block/frame/battery
Corrosion inside the cables

How did they check the battery? Or with what? Probably the best way is with a carbon pile load tester. Not done too much anymore, in favor of small handheld conductance meters.
