The man at autozone said my battery was fully charged. And my car runs after the jump without the battery connected. What could be the issue?
it started from a light being left on for at least 6 hours. I got a jump start to get home. I took the battery to autozone and was told it was 100% charged and it could possibly be the alternator. However I got a jumpstart and when my truck was running I disconnected the battery and it stayed running
If the battery is fully charged, there shouldn't be a problem with alternator. With the vehicle electronics, engine running, it's not a good idea to disconnect battery. If your saying the vehicle won't crank without a jump, check voltage at starter circuit, no jumper. Any testing, make sure the tranny is in park or neutral and the e-brake is set.

Well when I drive after im being jump started, the batrtery gauge jumps up and the check gauge light comes on. I just got off the phone and the man at auto zone suggested that the alternator was overcharging the battery

Use a digital multimeter across battery posts, everything off, take a reading. You said they checked your battery was it overcharged? I want to see the voltage reading.
