Prius C Hybrid Battery Just "Replaced" by dealer under warranty,.. how to confirm?

Correct. In Toyota’s Electronic Parts Catalog for your car, Figure 82-01 (Battery & Battery Cable) shows that the battery cooling blower assembly (part number G9230-52020) is not included with the HV supply battery assembly (G9510-52031). Under that figure, image 2/4 shows the blower, and image 4/4 shows the HV battery.

 

You'd think they would have taken a few minutes to clean the fan while they had it out.

I assume you went ahead and cleaned it yourself while you were in there? Assuming it was dirty enough to warrant cleaning, of course.

Here's some info on Prime Earth. Basically, they spun off from Panasonic and supply Prius & GM hybrid batteries.

The # on the housing has a date code as part of it. But even then you can't be 100% sure without opening up the pack itself and looking at date codes on the individual modules. Why? Because I suppose it would be possible to put a new housing in an old unit. Or put the old housing on a new unit.

If you really don't trust them it would have been best to have it documented ahead of time, or watched them do it, or asked to see the old part.

good news, dealer installing old battery pack has never been reported here. if you have trouble down the road, that's the time to open the pack.

 

I'm not sure about the C model batteries, but I know the Gen 3 assemblies you can pop off the ductwork above the ECU section and it provides enough gap to look at the serial numbers on the first few modules. I would imagine new modules should have an R (2016) or S (2017) for the 4th digit. It would also depend on where the serial number is printed. Some Gen 3 modules have the number printed full length near the top center of the module and others have it printed in two rows, but under one of the metal brace tubes, which makes it tough to read.

 

It'll be too late by then.
Heck, even now the dealer could say the customer changed it after leaving the dealership.

good point, but i wouldn't worry about it. think of the hundreds/thousands of people who get new batteries either warranty or not. how many open it up to make sure it's new? might as well get a second opinion every time you get a filling or other.
now, i wouldn't put anything past dealers, but i hope toyota has a way of verifying these things.

 

Welcome - sorry you continue to have a problem with your C.

Now you have documented the serial number on the current pack housing, so you at least can confirm if they replace it again.

Has the health of the 12 volt (smaller) battery been checked? If you can't get to Ready and all the dash lights are on, you might not have enough juice to boot the computers (which it pretty much what that accessory battery does).

(Note of caution - if you try to jump the car, make sure you do it properly - lots of folks, including roadside service, make expensive mistakes there!)

 

if that included a load test, it looks fine. i think you'll have to see what codes toyota comes up with. maybe when you reinstall the 12v, it will start.

 

Yeah there's a measured Cranking Amps value.

They might have just plugged in a speculative CA value for "rated": I had a hard time finding CA info for Yuasa, there was nothing on the label, and difficult to find on the web. I suspect "rated" input is just so the tester can give you a verdict, ie: good, borderline, bad.

Cranking Amps is typically higher than Cold Cranking Amps?

 

So did you happen to see your dealership again? What happened next?

looks like batteries don't last in tropics?

 

Glad it was simple. You're right; that happens a lot with the orange interlock.
I suspect you don't have the Prius PID codes installed. This thread should explain.
