2006 toyota prius with error code p3024 and a freeze frame error code of p3000 and a pending error code of p0a80. Any ideas before I scrap it?

I did. 2 of the cell for the hybrid battery were bad. Had. A guy from CT come out and do it but I watched him do it so I could do it again. Car has been sitting idle now for about 3 months with a new problem. Haven’t had time to look into it. Nothing related to the old problem. Def don’t get a whole new battery when just a couple cells are bad.
