I've seen "NEW" batteries fail within a couple days purchase. I would have the battery, new or not, tested along with the alternator individually at a different place than you've already had your alternator tested. This would eliminate a false positive on the alternator test and verify your new battery.

Assuming that both the battery and alternator test good, I would remove, inspect and clean the typical power cables in your auto. These would be all the red power cables from battery to alternator and battery to starter / power distribution block. Also clean the negative black wires and grounds.

I agree with bdahl, it seems to be a bad contact. Check voltage on battery connectors to see if you have same voltage than batt. It's not a battery drain.

You may need to have terminal cleaned/rubbed and tight connection w/o breaking bolt.
