My daughter’s 1998 Volvo V70 had a dead battery. She had a jump start and went to an auto parts store. The battery did not hold a charge and she needed a jump start again. The parts counter person looked under the hood and laughed when he saw a deep cycle RV battery installed. (Two years ago I had put in an spare RV battery and had put it in to replace a bad battery). He said, well that’s the problem. There’s an RV battery in here.This isn’t an RV! He did something, when jump staring again and the alternator caught on fire. The auto parts guy said that it was caused by using an RV battery. Now my daughter is mad at ME after two years from when the battery was put in!
Am I correct in saying that either the car has a short circuit somewhere, the voltage regulator is faulty, or the battery terminals are dirty (possible the ground is not making a good connection), and the reason is NOT because an RV battery was installed?
Should you trust an auto parts counter person to make diagnosis?
