Dead 2007 Prius

OK guys, replacement block is installed and after a few failed attempts to boot it finally did wake up and work correctly. It's got a mind of its own. I would have expected the same symptoms as last time and I would have at least expected it to through some fault codes, but now I know anything is possible with this weird car. I wonder if clearing the codes to get it home had any adverse effect, causing some of these unusual circumstances. Any thoughts?

 

Yes, dolj, the car is working perfectly for now, but I know it is only a matter of time before I must whack the next mole. I plan to get a whole new pack next time or maybe sooner.

No, TMR-JWAP, I did not do the work same as you. It sounds like you have been working on these hybrids for a while. I will remember your protocols for my next experience. I'm glad to see that the start button needs to be pressed twice. I thought that was abnormal. Maybe it was, I seem to remember trying more than twice.

 

OK gentlemen, I have wacked the mole twice and it appears that the season is on for failing cells. Looking at options for replacement batteries, I find;

"Reconditioned" such as the offering from "Green Bean Battery" which looks good and has a 5 year warranty, and they come to your location and install it for you. But, I remain suspicious of any "reconditioning" of a sealed unit that can not be opened without destruction. That said, it appears they have a process that may be valid.

Also there is an option on ebay for a new aftermarket battery pack from Concentrated Batteries in California. They use round cells and have designed a pack to fit in the original battery housing and uses the original battery control system. This one comes with a 3 year transferable warranty.

Both options come in around $1500. Your thoughts are appreciated.

 

Great ideas. I am not set on the cylindrical design, it's just an attractive looking offer and I have had great luck with Panasonic batteries in the past. Am I correct in assuming "2k1toaster" is a member of this forum and makes battery packs? How much? Contact?

I didn't know that the newer generation Prius uses the same batteries (modules) . I am not in Detroit. Currently I am in southern Florida for the winter. You have options to offer? I will check local yards in this area.

 

Brake actuator/accumulator was just done under warranty, electronics all working as they should, engine runs well w/o excessive oil consumption. Florida car=no rust. Cars value with bad battery = zilch, with new battery probably $4500 to $5000. I do my own work so investment is limited to parts cost. I have never paid a dealer for a repair and I am nearly 6 decades old. Where in Florida is one likely to find a pack from a late model Prius?

 

Thanks Ray

 

I find it incredible that 2k1toaster starts his post with the same verbage as the ebay listing. Either 2k1toaster is selling his battery on ebay or someone is copying someone elses writeup. And there is more the same as well.

From the ebay listing:
What is this?
This is a DIY kit to completely and fully replace your aging or dead Toyota Prius Hybrid Battery (a.k.a. Traction Battery) with brand new battery modules, bus-bars, battery wiring harness, and interconnects. You retain your original metal enclosure and hybrid ECU.

Will this work with my Vehicle?
This is meant for Generation-2 Toyota Prius vehicles, model years 2004 through 2009. We also have kits available for Generation-1 (2001-2003) and Generation-3 (2010-2015) available with request. These modules will work in any number of Toyota and other makes that use the same Panasonic battery design, but the wiring kit is specific to the Prius. With extra (and non-supported) DIY, you could potentially make it work with many more vehicles.

How Much?
For $1490 you will get a brand new hybrid battery backed by a 3-year and unlimited mileage with a full transferable warranty, There is nothing comparable out there. All other options that are not original Toyota Hybrid packs, are used modules. Some are refurbished and/or balanced to be better matched with one another, but they are still all used batteries from wrecked, salvaged, totalled, or other failed Prius vehicles. When you start driving on your new pack, it starts with zero miles on it, just like a brand new Prius from the factory.

For $1600 and approximately 4 hours of installation time, you will get a brand new hybrid battery backed by a 2-year or 25,000 mile warranty including fleet vehicles. There is nothing comparable out there. All other options that are not original Toyota Hybrid packs, are used modules. Some are refurbished and/or balanced to be better matched with one another, but they are still all used batteries from wrecked, salvaged, totaled, or other failed Prius vehicles. In contrast these batteries from NewPriusBatteries.com are brand new and never used. When you start driving on your new pack, it starts with zero miles on it, just like a brand new Prius from the factory.
