Just Replaced 2 Bad Battery Cells In My 2007.. Now All Dash Lights Are On And Engine Wont Start

Tested and replaced 2 bad battery cells in my 2007 Prius... Got everything put back together and now all dash lights are on and engine won't start... When i try to shift into drive or reverse it goes directly into park... I tested the battery without removing the safety key and the inside terminals are at 220 volts and the outside terminals are at 0 volts as shown by photo... Any thoughts from the experts here on PriusChat?? Maybe a fuse somewhere?? Im going crazy.

 

Yeah im a idiot... I forgot to press it down to lock it... 1000x thank you JC91006... Works perfectly

 

OK, now i seem to have a different problem... Been driving it for the past 2 months (1200 miles) without incident after I replaced 2 bad cells... Actually getting ridiculous milage 50+ MPG... Thursday all the dash lights came back on but now i can hear the hybrid battery fan running full blast in the back which it never did when i originally replaced cells... When this happens, i noticed the engine runs constantly and seems to miss or cutout when i accelerate.. As I'm driving, while watching the Energy Monitor, i notice the battery seems to be charging (charging arrows going into battery level) but will not discharge (arrows going out of battery level) no matter how i drive it and battery level seems to stay the same.. When i come to stoplight, engine normally will shuts down, allowing me to accelerate using only my battery up to 35-40 mph then engine will kick on... It no long does this, engine runs constantly and will not disengage... Now heres the weird part, started it today and no lights on dash... It drove flawlessly for about 50 miles then light came back on and started running like crap again... Drove it home, Disconnected the 12volt battery for a couple minutes and when i restarted, lights were gone and drove flawlessly again for approximately another 50 miles then lights came back on... Drove home, disconnected 12volt again and lights gone again and runs fine... Just wanted to check Prius Chat before i take to dealer again to run codes... 12volt battery tested at 12.45volts.. Any thought from the experts here on PC??

 

Yeah but it is totally acting different from the first time... Engine didn't miss/shudder and the hybrid battery fan wasn't going full blast... And it runs perfect when the lights go away.. Like it will be driving perfect and the second the dash lights come on, engine starts acting up... Do you think it could possible be the ecu??

 

Taking it to the dealership but they charge me $100 every time i take it... Once for the airbag and twice for the initial diagnostics for the battery.. The same dash lights are on but like i said, it is acting different from the last time... Guess maybe i should invest in a code scanner if I'm gonna keep it

 

Well i just ordered a mini vci.. If i would have know they were that cheap would have ordered one a long time ago... It will be here Tuesday... Thanks for all the help guys... Ill post what codes pop up

 

Finally got Mini VCI... It pulled 4 codes.. First is p3000 battery control system and X is marked under current and history... Second code is p3024 battery block 14 becomes weak and X is marked under pending and history.. Third code is c1259 HV system regenerative malfunction and is only X under current.. Finally forth code is c1310 HV system malfunction and also is only marked X under current... Can anyone make any since of this as it is way over my head... Can one malfunction cause all 4 codes?? Im so frustrated with this car
