    I happy 2007 Prius which I purchased two years ago. One year later I had to please second battery. About six months later that one went bad and I had to replace it again. A couple of days ago The red triangular warning light flashed on and off within a couple of seconds while I was driving. Today it is happened twice again. I ran the diagnostic found that the battery is running at about 13.8. Is it possible that it's a bad battery again? Why does the light come on and then go off again so quickly?

    You should check your engine oil level, most likely low on oil

    welcome!
    are these all the 12 volt battery? if so, it sounds like something is daring it. but you can't test it with the car in ready.
