My son took it home and it was charged up to 12.5. Put the charger on overnite and it came back to 13.8. Everything is good. Thx for all the input.
13.8V suggests a float charge. Turn off the charger and let it sit for an hour then check. Even with a good battery, it will drop back to around 12.7V after sitting with no load.
If that goes well, swing by an auto store. Most will do a load test at no cost. Even if the voltage looks good, it may have lost much of it's storage capability and it will show up in a load test. You don't want to go out boondocking and find out, the battery really was still a problem.
