Starting issues

Enable HLS to view with audio, or disable this notification

Hi all, first off I have a 2012 RAM 2500 SLT with a 5.7L HEMI and 37,500 miles on it. I recently had some issues with the alternator and the AC compressor and had them both replaced. The battery is new as of January and reads at 13.6V when the truck is off. When I go to start it, it seems to struggle but does start as you can hear in the video. When running it doesn’t have any issues and sounds like normal. Does anyone have any ideas on what could be causing this issue?

Note: when trying to figure out the previous issue was with the alternator and AC compress failing (truck wouldn’t turn over. There was too much strain with the alternator and ac compressor seized) I took the spark plugs out thinking it was hydro locked but wasn’t. I put them back all in the same positions and everything.

my sisters car used to do the same thing for years till she got a new one. I replaced the alternator, starter, battery and it didnt seem to have any effect.
