2007 Prius - Check Engine, Red Triangle, VSC Lights - 12 volt battery issue?

In the office the first thing I would say is, "Is it plugged in? Is it turned on?" It is remarkable how many times that all it took to solve the problem.

OP, your 10 year old battery is about as good as it gets. The only sources of reliable replacement batteries are through a dealer (new cells from Toyota), a used battery as tested by the member referenced earlier (not as good as new), and the kit with the new cells, also already mentioned.

Just my opinion: Anyone else offering to replace cells or the entire battery on the cheap is doing so by scrounging whatever cells they can find on the market. If you want "cheap" and "fast" you won't get "good". If you are selling the car the day after the install then if it is just a matter of "don't ask, don't tell" then drop in the cheapest battery you can find that won't throw a code and we'll give the same advice to the next new member that posts "I just bought a 2007 and the dash lit up and the car lost power".

Spend the money to buy a battery that can be expected to last at least a few years. It is cheaper than buying a newer car. Your 12v battery would benefit from a battery tender which is inexpensive.

I wish you the best of luck whichever path you end up taking.

 

Diy on the prius is actually not hard and very inexpensive

1. Water pump and belt $60
2. Inverter pump $80
3. 3 way coolant valve $80
4. 12v battery $200
5. Coolant $50

So $500 would've done it with some basic tools and about 2 to 3 hours of your time

 

That is called diyourself

 

Diy hv battery can range from $100 to $2000. Depending on the quality and longevity you are after.

Yes I think anybody that can lift 80 pounds out of the car can do it

 

If your local Toyota dealer will sell you a Toyota hybrid battery at retail price it will hopefully be around $2,100.
You'll have to call and see.
If you know someone who has a business, perhaps they can get a lower price (wholesale) without paying tax, and you can buy it from him for less. You guys will have to work out the sales tax.

 

And so, like clockwork, we return to your contention that the reported information is likely to be wrong, and to the simple question, how likely do you think?

And by "how likely", I mean, can you offer any substantiated example at all? We both know what that would take, and it should not be impossible, or even hard, if it happens as commonly as you suggest.

A good substantiated example would be a significant contribution to PriusChat, and one you might be able to make.

They will get your 'core' which contains battery modules that are newer and or in a better state of health over what they're actually selling you.

Better for them to have a not working set of factory matched modules of the same age (core) over a bunch of used mix matched modules from different vehicles (which is what you would be buying), then they can take your rebuildable 'core' pop one or more modules in it and sell it to the next guy. Rinse, Repeat, Profit.

 

That's not what I said at all.

I said that it is POSSIBLE for it to be wrong if the 12 V system is out of spec.
I also said that not checking the 12 V system first is just stupid.

A lot of factors come into play in GUESSING how likely it is to be wrong.......and the whole point is to NOT GUESS but to test it and be sure.

Your incessant and unproductive arguments are becoming tiresome.
Give it a rest please.

 

The components can be recycled.
I believe that there are laws requiring that to be done.

 

Panasonic isn't the maker of the OEM modules, they were bought out many years ago. He could've given you any answer and you wouldn't have known better

I don't believe this guy knows what he's selling

 

From 2010 PRIMEARTH EV ENERGY produced the modules. Which is kinda still Panasonic, but they have a small ownership

 

If they are indeed new, they probably are sourced from China. Were they prismatic or cylindrical? Otherwise they are just recycled old modules. If they were from a new pack (towards 2015), that wouldn't necessarily be bad.

I would hope that you keep pressing him to supply some documented evidence of these claims. They are easy to make, I wouldn't readily believe claims made by the manufacturer either, without further documentation of the testing regime.

A member here, 2k1Toaster,, who has the equipment to test these things tested the capacity of a set of Chinese cylindrical modules (CEBA, I think) with a claimed 6500 mAh capacity and they came up well short, nearly only half of that capacity. This datapoint spearheaded the desire to do better and he has brought to market cylindrical modules with a true 6500 mAh capacity. He uses his own trusted manufacturers to make the modules.

There are a number of suppliers in China that make prismatic knock offs and others that make cylindrical modules that all fit, but so far, no reputable builder will use them, because they are just not of good enough quality. Even so a set of these will cost $1300 by the time they are landed and all fees and taxes are paid.

So, my caution is caveat emptor.

 

A rebuilt battery is only as good as the person that's doing the rebuilding, they have all skill levels.

Like the mechanics at your dealer, some are really bad and some are just a little bad
