Also sometimes a car with a bad battery wont even take a jump. So that's always something to consider too.

My dad (who taught me almost everything I know about cars) was the same way. He had a Caddy that wouldn't start without being jumped. He had called me up and said the Caddy was dead, so I brought a battery charger. We charged the battery for about 40 minutes, then switched to engine start and it fired up. I told him the car needed a new battery, he said exactly what you posted "it can't be bad, I have lights and the horn works". I told him "humor me & replace the battery". He did and Voila!!!! no more problems.
I'm pretty sure JAR has replaced the battery already...
