Okay so I got my oil changed two weeks ago and the mechanic said my battery needed to be replaced soon. My car is a 2015 Mexico built and I'm fairly certain it was the original unit. So last week I went to advance auto and bought a new battery and put it in on Thursday 5-14. I had no issues until today. I washed my car, then went out to run some errands, I turned the car off twice during my trip and started no problem. Got home around 5PM and then I went to start it at 8:30 and it won't start. dash light, radio, HVAC comes on but no start. I checked the voltage at the battery and it reads 10.5V with car off and 9.4V with car on. Obviously way too low to start the car. Did I just get a bad battery? did I do something wrong installing it? Has anybody else had this issue? I didn't leave any lights on while it was parked for 3 hours and I didn't get a battery light or anything while driving.
