With the engine running, the voltage should be around 13-14 volts. Possibly a bad alternator. Also, if the battery has tested OK, then check for something that stays on (Glove box or trunk light etc..). Depending on what they used to test the battery, it might still be bad. The best way to test a battery, is with a load tester. A bad alternator can take-out a battery, and a bad battery can take-out the alternator. They should both be load tested (battery and alternator), and the cables/connections checked and cleaned.
