Additionally, a smaller battery means that it would be charging with more current than what is recommended leading to its early failure. Also, a smaller battery usually has less reserve capacity which means that the other electrical/electronic components will not get adequate current at the recommended voltage and hence the alternator will have to work overtime to compensate. In summary, a 65 AH car battery is absolutely not the same as a 85 AH car battery even though their voltages may be the exact same. This battery saga alone is more than enough for me to concur with your initial assessment that they may not be qualified to work on your car. In fact, it may not be far from the truth to claim that they are not qualified to work on any car if they do not know something as basic as this about car batteries So please get it replaced as soon as possible.

Agree that the replaced battery may not be the correct replacement. The engine problems may be over for now but electrical snags may be in the horizon. It needs immediate attention.

What's the new Amron battery model number?
Did you collect & retain the battery cover that was not put back?

Hi, Your Tucson front bumper was carelessly stowed away and was scratched. Were the scratches re-painted/removed when you got your vehicle back?
