Prius C Won't start

nope, it's the 12v

 

Agreed 12v is dead. Charge it to get going again, but you really should replace it altogether. You got your money's worth and then some.

 

I'm not sure I understand your update correctly- Are you really certain the car is off? I don't get how you would hear engine noise and see a check-engine lamp unless the car had somehow gone into ready mode.

 

"Lean" harder !!!
At that age, the 12 V is overdue.
Be sure that the new one is fully charged.
Consider investing in a battery tender.

 

What do you mean you hear the "Hybrid Engine" running?
There are electric motors...but if the vehicle isn't moving-parked...you shouldn't hear anything.

 

Yes it's an odd battery. They usually go for $200ish by themselves, plus whatever to install them.

Glad you've got it started, good initial step to recovery.

AFAIK it's only the 2012 that needs underseat access for charge/jump. All later builds have a pop-up terminal in the underhood electrical panel.

 

congrats, all the best!

 

Try a different dealer to see if they have cheaper price. I just replaced OEM battery from a dealer last year here in SoCal for only $225.

There's a thread with battery from Pep Boys and when I checked it was like $190xx something. Not sure it's better than the OEM at cheaper price or not so I went with the dealer one.

 

First, that price is OUTRAGEOUS.
(Edit: Sorry, just noticed where you live. Maybe not so outrageous after all.)

Second, most batteries don't last 8 years.
5 or 6 is more realistic for the models with AGM batteries.

 

Sorry, could you pls. provide battery part no.?
I am also looking for my 12V battery replacement and don't know what part no. it should be.

 

It is not necessary to have a "part number" to shop for a new battery.
Just get one that is listed as an "exact replacement" for that year and model of car.

 

Last night my 2014 Prius C was dead, just all of a sudden. Called today to get a jump. 1st tech didn't really know hybrids but connected to the jump terminal, charged it, but no luck. Had another tech come out & right when he got there, I got in the car to open the hood and the lights were now strong and it started! He mentioned something that I haven't seen anywhere and I realized I had done it by mistake after the 1st tech had left: If you turn the key twice in the door for the "unlock all" function, that resets the computer/electrical system or something. I'm not sure what caused it to go into that "dead" mode. All I know is that it seems fine now. Anyone heard of that?

 

It could be that "unlock all" simply draws enough current to knock out the computer and cause a reset when the battery is very low to begin with.
