2005 prius: replaced engine. 200+ volt battery shows almost no juice. Car won't start our even go in gear. ??? ANYONE??

the clicking indicates that the battery is dead or flat. The only test is with a load tester. For a battery to fail quickly especially in cold weather indicates that it was on the way out.

You need to replace the 12 volt auxiliary battery.

The image of the 2 cars opposing each other looks like it wants you to 'jump start' the 12 volt system of the car. SO test the 12 volt battery and try. Videos on youtube show how to read the 12 volt battery in the MFD and how to jump start the 12 volt battery.

Do you get warning lights on the dash ?
If yes, a mechanic would check for voltage at the starter.
The circuit between the key switch and the starter has a neutral or clutch safety switch that could have failed.

It can be the issue with weak battery or faulty battery or if battery is ok,then its faulty starter causing the issue.

A battery can show 12 volts yet still be dead (not pushing any amps). Many battery places or auto parts store will do a free test.

the clicking that you hear is coming from the starter relay. sounds like your ignition starter switch or ignition lock cylinder is bad.

battery should be showing 12,45 - 12.6 volts when car is standing still. also batteries getting old colects sulphate on plates ,this degrades the cold start performance. you can see that cranking amperage on stickers of batteries. for example 90 amperes 750 cca battery is required for my car but les wont crack it even it is 90 amperes but 640 cca. mainly lead acid or dry type batteries needs to be charged more than %40 of its capacity. 12 volts is only the ~%25 of its capacity and it seems yours is dead already.

As far as I know, both my original 2005 and my current 2007 flash that light when the car is off. I believe that is the whole point - to show any would-be thief that the car may be "protected." A small battery can flash an LED light for weeks or months or even longer, so I wouldn't worry about the blinking LED draining your Prius' 12V battery.
