Car starting problem

Hi all,
My SUV had a problem starting; when I turned the ignition key, I could hear the cranking sound, but the car wouldn't start. I figured the issue is the battery.
I took it to the shop to have it tested, and although the voltage checked, the amps test failed, so I picked up a new battery.
I put in the new battery in the car, and I could see the lights/computer is working. But this time when I turned the ignition key, there was no cranking, and the car wouldn't even attempt to start.
Is this a problem with the starter? But it's strange that with the old battery I could hear the cranking, and as soon as I replaced it with the new one, I couldn't even get that.
Should mention that I checked the voltage on the new battery after a couple of starts and it's 12.4V; is that too low for a new battery?
Would appreciate any help!
Thanks

Year, make, model at least before anything else please!
Basic bull: Trying to read thru that mess it doesn't crank, hence doesn't start then you say after a couple starts (did you mean turned key a couple times or it finally ran?) is reads 12.4V means little so far. New batteries are not charged - you do that or the outlet does before you install it. Just from being factory filled it would usually have enough to start an engine but not done yet. Should read 12.6V after charged and a wait time with charger or engine off for a while if so.
The common thing is it tried to crank engine with old battery and doesn't with new. This so strongly suggests you had to disconnect old battery (duh) to take it out and clamp on the connections to the new so I blame the clamps ends of cables for now.
Did you bother to clean and grease them up? Did they even stay on snugly when installed?
You can't have a clue if computer is working because a few dash lights turn on so forget that - bad cable ends, dirty, broken or not tight is the guess of the day,

The battery cables are connected to the battery terminals pretty tight.

OK - Tight isn't proof of a good connection. 2010 suggest a tad new for wild problems with corrosion but who knows? Those should just be cheap zincish (?) U-Bolt clamps to battery, quite common and so cheap no good fast if exposed to corrosion or not tended to - almost nobody pays attention till a problem crops up.
Try with pliers to turn just carefully on them. They shouldn't but can crack that u-bolt such that the bolt you tighten is tight but connection is not.
This strongly point to this and should be a listed routine to check on this stuff anyway and isn't. If everything about them looks fine next is chasing voltage drops while starter is requested (a huge demand on a battery) you'll be able to see where it's losing proper current. This could also be at the starter motor end or engine block end of battery cables AND a trigger wire at starters must be good and can be checked that it lights when starter motor is requested by key. If nothing it's another chase,

Did you accidentally reverse the battery connections at any time? Don't be afraid to admit it, we see it all the time.
Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.
