Dealer service center says I need a new HV Battery but I think there might be a different probelm

I have a 2004 Gen II and my HV battery died in August 2014. The first warning signs were that the red triangle of death lit up as well as all of the other warning lights. The cooling fan for the battery came on and was I drove the display battery would continue to get lower and lower until the car would not move unless I stopped it and restarted it. I ordered and had installed a remanufactured battery with Gen III cells. After installation everything ran good again. The battery display kept a high charge and the icons on the progressive ride screen continued to generate the 50wh cars that showed charging in five minute increments. Well now onto my current issue. Just last week I started the car and all of my warning lights came on again. I looked at the battery display and it was all the way down to 2 bars. As I sat and let the car warm up and began to drive the battery icon regenerated to near full and full. The car is running good and the gas mileage is as normal. I thought that maybe it was a one time thing since the battery regained full charge but after resetting the lights (by disconnecting the neg on the 12V) the same thing happened again. I start the car and the battery display is low, I drive and the display get fully charged and remains that way and the car run good, however the 50wh icons on the progressive screen never generate. I took it to the Toyota service and that put the computer on it and say it is the HV battery. I know how the car react when the HV battery dies and that is not at all how it is acting now. Could the service people be wrong. What else might my problem be? Any help is hugely appreciated

I bought it from Prius rebuilders on the East Coast. I spoke to them on the phone today and they're going to look into it. The codes are P0A80 and P3016

 

and it's not unusual that the car is reacting different this time with battery failure than it did last time?

 

thanks to everybody for your input. I always just like to get a second opinion. I will let you know if Prius rebuilders honors the warranty

 

Yes the lights are on right now
