    Well, I ran techstream and I see the P0AA6 and detail codes 526 and 612.
    So, it seems that this indicates a leaky cell in the battery. I was hoping to not have to pull the battery, but here we go again...
    If you folks have this situation and need to replace one blade, where do you buy it?
