HELP!! Replaced Hybrid Battery still not working

Hello all as the title says i had the POA80 code so i replaced my battery. Well after that it wouldnt go in to drive or reverse. So I thought it was the 12v battery since the car did set for a month plus. So i charged the battery over night and put it back in still will not go in to drive or reverse. still says check hybrid system on the dash. i have checked the there is no dtc and only thing i see is in the permanent section and that is the poa80 code. i have checked the on board diagnostic thing and it shows no current stuff also.

When i power on the car i can here my battery (probably fan) but the car beeps and bitches at me and will not go in to drive so im at a lose. also the dome light will not shutoff.

 

Hey everybody thanks for the replies. While i was waiting for this to get approved. I disconnected everything battery wise and let it set for a few and then reconnected everything and it was fine oddly. I know when i made this post i was quite anxious. Thank you all again if i had seen these they would have helped for sure.
