Terminal replacement/won’t start

I just replaced the battery terminals. I have juice but just 1 click and no go when I tried starting. Tried boosting and nothing changed. Wondering if anyone had insight?
I’m thinking the metal terminals I’m using has something to do with not jiving with the lighter metal connectors from the cables?

 

I would start by making sure all connections are on and tight. If you have an alarm with starter kill, make sure it’s not armed.

 

Thanks,
Problem solved. I used acid and then baking soda solution to clean everything off. Connections were probably not as tight as they should’ve been.
