Alarm keeps going off?

I saw smoke coming from the front end of the car. I had to move it quickly because of another car and so I was focused more on where I was going to park it rather then anything else. I noticed the burning smell shortly after starting it up and noticed the smoke after parking it.

My next step is to purchase a battery charger this weekend.

I wish I could offer more info.

Thanks for your any advice.

Thanks Joe!
I will hopefully get the battery charger tomorrow, along with an extinguisher and see what happens. I'll let you know.
I really appreciate your help.

Thanks,
Kathy
