HID Headlight Problems - Need help diagnosing

All,

I am trying to see if my charging system has issues.

I have the retrofit HID lights that Fred created and have had issues "firing" them in the past. Last night I was driving as twilight came on. I was driving with the radio on and tried to turn on the headlights. The lights did not come on and the dash showed the battery icon. The spoiler raised (at 40 mph) and the radio began studdering. I turnd them off and tried again. No luck. I drove home without the lights but with the dash lights on. I pulled in and hooked my car to the battery tender. It registered 1, then 2 and 3 lights when I left it last night. I got up to 4 lights first thing this morning. Here is the pic.



This morning, it was still at 3 bars until around 8AM when it finally went to full charge.



So my questions are...

1) Is it normal for a battery to be low after a drive?
2) Is this an issue with the battery or the alternator?

Thanks, John
