Is it worth replacing high voltage battery?

There are reconditioned options for maybe $1000. So less than a newer car for another couple of years if that is the plan. Could add resale as well.

 

Maybe someone rebuilds there. It is a low startup cost business that could operate out of a home. Check around, could be worth a drive. At least use these prices as a reference. What does a dealer want for the part? A general diy or mechanic could change. Note this company is selling new OEM for 2400 and buys from Toyota somehow.

It's worth it getting a new factory battery, another 170,000 trouble free miles.
Don't buy a reconditioned battery, it's a used battery, buy new, have it installed at a toyota dealer, 2,500$ total, and then just new rubber and brakes when needed.
Do a search for reconditioned battery threads, they all point out.....buy new

 

welcome!
it's a tough choice. depends somewhat on how long you plan to keep her. most reconditioning is a headache, with multiple replacements under warranty, and then you're on your own.

a ten year old car is likely to start having issues in the near future, but cannot be predicted.

 

has anyone tested the 12v and printed out the results for you?

 

what if they replace it, then tell you you need another $2.000. gizmo needed?

 

not because of the battery, but prius has several high cost systems. a/c, brake actuator, transmission, inverter, and etc.

 

all the best christine, please keep us posted!

Jeff, I'm a believer in the reconditioning. Yet, it still bothers me that you throw this out there without including the fact that it will frequently NOT cure/recondition a battery that already has a failed module or modules. Once the triangle comes into play and the "Block x becomes weak" fault appears, I would venture to say, in many if not most cases, it's too late for the prolong unit to truly help. Following replacement of the failed modules, I'm confident it would be a helpful thing. I think you need to be a bit clear on this when you post about your system.

 

I was just answering the OP's question about shipping and gaining access to our products . Here is a more detailed response I just posted in another thread that describes more specifically what is required to successfully complete the reconditioning process:

"We have many customers who have extended the life of their battery by a couple years or more by using our products. There are several first person reviews attesting to this on PriusChat (Search 'Prolong Battery Systems'). By correctly load testing your modules (resting voltage is a poor indicator), replacing failed modules with good quality TESTED replacements, and caring for the battery on an ongoing basis multiple years of incremental life can be expected. You can give us a call at 800-589-0730 to talk about the process or read more about it here:

"Here is one example of the results of our products on a Prius pack with 140k miles:

 

Since the entire premise of grid charging is to continually ensure all the individual cells are topped up then if one of the cells in a module is either on the verge or has already reversed, you are correct this will not miraculously cure that condition. What it will do is ensure any replacements (either new battery pack or a rebuilt one) are topped up so as to ensure the longest life possible out of your battery pack.

Assuming Christine has limited to no skills for DIY rebuilding I too would suggest she looks at a new Toyota battery replacement if the original has already indicated a failure (as seen via Techstream voltages and CEL codes).
