conipc, a new battery will have a voltage of 12.6 VDC with the engine off. With the engine running, you should be up at 13.7 or 14.4 VDC (depends on the style of multimeter you have). Being at 12.44 with the engine off and all loads de-energized, that is a little on the low side, but not horrible. That is just saying that your battery is getting weak. You can do a load test in your driveway by simply connecting the multimeter across the battery and then attempting to start the car. The battery voltage should remain above 11.0 VDC. If it is dropping below 11.0 VDC, then the battery is starting to go and should be replaced.
If you need more help, just hollar.
