I just replaced my battery in October of 2016. Yesterday my car barely started and once the engine had started it took 2-3 seconds for the gauges to start moving. Normally it is instant. I got a jump from a coworker in the evening and made it home. I cleaned off the + terminal since there was some corrosion, and I was thinking that maybe the lug was not making good contact with the battery terminal. After cleaning it, I could tell the lug was not getting a good grip around the terminal and with a very small amount of force would slip off no matter how much I tightened the volt. I wound up tightening the nut a bit too much and destroyed the lug. Picked up a new OEM lug today and it went on easily and makes a great connection. Tried using my Stanley battery to jump start and it was a no go. Then tried jump starting with my brother's car and it was a no go. When I put the key in AECC my battery voltage reader is reading about 9.5V which I know is too low to start, but I'm confident I reconnected the lugs correctly considering I'm reading a voltage. Now I'm thinking something may be wrong with the starter, but that does not explain how I was able to easily jump the vehicle yesterday. When trying to start I get a clicking noise (see 1:00 on this video: https://www.youtube.com/watch?v=1TK8NxqJ4MA). Ideas?
