Help Battery/Startup Issue

CJBinder

Before I start, lets just say I apologize for stating anything newbie as I am.

So bought my second Z a few months ago. At the time, I had it inspected by a dealership and said battery was low. There was a recall with ignition which they changed out before I bought from private seller.

Then one night at home, like an idiot I left the heated seats on all night and next day. Needless to say it wouldn't start. It had the original OEM battery which I figured should be replaced anyway since it was 6 years old. So I bought the Optima Yellowtop Battery on Amazon. Installed without any issues.

But now it seems hard to start the car. When turning on to acc then on, wont start right away. I have to keep pushing the button over and over and finally it will start. On ac, it shows 12 amps and little under sometimes. Once it starts its up to 14 and over.

Its almost like a short somewhere, maybe from the heated seats? Altnerator potentially? Also note I don't drive it very often at this point as I am waiting for new tires and such, so I just go out for small joy rides.

Any ideas on what to check or what the potential problem is. Connections to battery look good. Maybe I should get the battery checked? Could it be a dud?
