Hi,
That is a simple mistake. However, an easy fix. I'm glad to know it's running, and you have A/C. It's been hot and humid here as well.
As far as the battery is concerned, it is a 12v battery. When the engine is running, the alternator will produce approximately 14.5, so that sounds perfect.
Regardless, take care of yourself, keep cool, and feel free to come back anytime in the future. You are always welcome here.
