2011-13% Battery Pack Life expectancy left

welcome!

how many miles/km? do you drive it much?

 

how much quarters do you have? Wack o mole is the game that you will play.

 

Those modules were completely drained before you even started testing them, as evidenced by the immediate drop below 7.2 when you attached something as minor as a 12v light bulb load.. Those are acting like modules that were drained, then left alone for a short time, allowing the voltage to recover, which NiMH modules will do. Are you sure you didn't completely drain the battery by running the car only on battery power for a bit? I would try charging the modules first, and then retest, before deciding about what to replace.

Or these are the absolutely most ragged out modules in existence. I suppose anything is possible. But a P0A7F battery deterioration code is an understatement for what you're seeing. That battery doesn't even have 1%. There is no way that HV battery could even begin to try to spin the engine to start it.

 

I do not know about "expert" but I've been to Panama.
It's pretty hot and humid there, and your car is 10 years old.

You can replace the cells individually - or - all at once but eventually you're going to probably replace them all if you keep the car long enough.
The cost is probably going to be comparable in the end but the disadvantage of replacing them all at once is that you have to buy them all at once which will probably be slightly cheaper than playing Whack-a-mole.
The advantage of replacing them all at once is that you only have to do it once - at least for the next 10 years or so.

I'm not familiar with your local fuel or any differences between the North American spec Priuses and those sold where you live.
How is the engine?
Do Panamanian Pruises have the same engine problems as those in the US?

If so you may want to look into that sometime soon.

Good Luck!

 

even with refurb ones?
