Battery/Alternator issue potentially? Please help

[amitmishra4]

Thanks for the quick reply. I am wondering if it was already shot when I got it.

The car starts up fine and it does all the checks (lights come on and go off) and the top goes down and up, so is it safe to assume the ECU is ok as are most fuses? Maybe the radio has another fuse behind the head unit that could have blown?

I bought it on a Saturday and started it twice or thrice at the dealer and then drove it home a 100 miles. Drove it once the next day on Sunday about 50 miles, then it sat in the garage for a week and started and drove it today about 20 miles and started one more time in the parking lot before it died. So all in all, maybe a maximum of 5 starts. Is that possible from a fully charged battery? All of the above with the AC and the stereo running and maybe put the top down and back up 5 times total. I am thinking i may not have even known the alternator was already shot? Or does that sound like too much for a battery to support with a bad alternator?

Thanks.
