yo RYAN,
ok
SLOW cranking is battery, terminals, cables, relay, or starter
pull battery and have it load tested for free;
Dead Cell; "... Sometimes, a battery will have just one cell go bad or short out. When this happens, the battery will seem fully charged, but fail to start the car, or it may start the car right after charging, but then fail to start the car an hour or more later. If this happens measure the S.G. in each cell. If one cell has a lower S.G. than the rest by a significant amount, replace the battery - there is no way to fix this problem. This condition most often happens to batteries subjected to lots of vibration, and sometimes to new and almost new batteries that have a bad cell from the factory..."

Headlights begin white and bright, when you try to start the engine, they dim to nothing or almost nothing then SLOWLY come back up to white and bright. This usually means the battery is bad and incapable of handling a huge request for power to crank the engine over.
Headlights begin white and bright, when you try to start the engine, they dim to nothing or almost nothing then as soon as you let go of the key, the headlights QUICKLY bounce back to white and bright. This usually means the starter is bad or the engine is locked up.
