P0AA6 code, Combo Meter, MFD Replacement, Reconditioning questions

ok I replaced the 12V battery, but I'm still having some issues with my car. I'm getting the P0AA6 code. I used the Dr. Prius app to test the life of the battery and it said 35% which I know is not good at all. I may run another test later tonight, and run the more detailed test to see what I can come up with. The car was sitting for a while in the Florida heat, so I know the battery doesn't like that. I hope driving it around a few times might revive it a bit.

On top of that, my dash lights have gone out. This happened once before a few years ago and somehow it turned back on again, but now they are out again. I know it's related to the Combo Meter, and I'm aware I can get one from Texas Hybrids online. I also found a repair service here in Fl that can do it for $40 + shipping so I might go that route to save some dough.

Also my MFD is out and has been out for a while so that has been driving me crazy and I've been wanting to replace it for a while. I think it's the sunburst issue. I can see it barely at night sometimes, but during the day it's impossible to see anything. If I have to do the Combo Meter I might as well do them both at the same time. What is the best source for MFDs? When I researched it a few years ago I found a few people you could ship them to and they will repair and ship back, but I'm also open to either getting a new one if possible or used on Ebay. I have the touring edition so I know I have to make sure I get the right MFD for my car.

So yeah I'm hoping the hybrid battery will last until I can get my hands on the new sodium batteries. Do you think I should attempt a reconditioning on the hybrid battery before then? If so what is the best method for this? I've been wanting to learn how to do this for a while. If I can invest in conditioning tools that will also be compatible with my new sodium battery that would be ideal.
