Car Wont Start but has a new battery

Car wont start but clicks..has a recent new battery installed by a local store for free as long as you buy the battery..as you know..not all store clerks are mechanics. .so as you can see here..after a few months or even up to a year, I have seen this happen..loose terminals..dont just lightly wiggle them..Grab them and see if you can spin them..bad connections will cause a no start/no crank but then starts with a jump..and then starts ok after that, till it dies again. .check those terminals S2E30 Visit my store for Cool Merchandise https://teespring.com/stores/cuda-garage also watch this https://youtu.be/k3Uf43kYG7g
