rotated 2 traction batteries and none give the 3 clicks for start

I have a 2006 and 2007. 2006 has 250k. I have a few traction batteries I replace every 6 months or so. Put one in the 06 today and no start, no 3 clicks all the normal lights with triangle. Put the old one that was in and had same results. I did not disconnect 12volt neg as it never mattered in the past. I did disconnect and no change. I am thinking this is pretty simple most likely relays? I have never had this problem in the past and I have done this pretty many times. OBD shows nothing. I have a prius diagnostic that I have not used yet as the old laptop needs to be charged. I do not know what and where the relays are that might need to be checked. Looking for some insight. Thanks

 

code was a POAOD. Cleared code and restarted. Everything was fine. Still do not know why it happened. I am going to put other battery in and see what happens.
