With engine running, probe the battery terminals with your multimeter. Should be around 14V.

If you have AAA, call them, they offer a free battery service and will check out your entire charging system at no charge. It seems like both are bad, and the AAA sells a new battery with a great guarantee, all brought directly to your location.
