    Had P0A80 code and battery was replaced. Code came back shortly after the new battery was put in. I'm trying to figure out if the cause of the code was actually the battery or if something else triggered it. I have no idea how to interpret these readings. Can you guys tell me what these two pictures tell me about the batteries?

    The P0A80 code is caused by a problem with the hybrid battery. Where did you buy the "new" hybrid battery from and how much did you pay for it? I hope it came with a good warranty. How many miles on the car?

    Which battery did you replace? The 12v or the Hybrid Battery?

    Was it a NEW battery pack, or refurbished? HUGE difference.
    Did you replace it, or have someone do it?
    Is it the Sodium Ion pack from Jack?

    Who diagnosed the issue? How did they do it? Where there other codes?
    Other issued can trigger that code and it not be the hybrid battery.
    Where all the codes cleared before and after replace the battery?
    Was/is the 12v battery FULLY charged?
