Help car won't start in the morning
 

the car is a 2001 max. this is the second time happen, this morning when i tried to start my car it didn't cranked it 3 times and waited like 5mins and then started it and work well, so the battery can't be the reason, and i replaced the starter last summer and it is working. Then i went to school and after class (1hr later ) the car started fine one crank. the only thing i can think of now is it can be eaither the spark plugs or the new battery terminal i installed buut i installd it like a month ago and this started two days ago. What do you think can it be the spark plugs?

here are the pics of the terminal any thing wrong with it?
