Worth a rebuilt hybrid battery?

Oh my that's not good. Will check with the vendor of the ODBII vendor.

 

So an update. I finally got a replacement battery pack BUT ... the store didn't have the casing. So i bought 28 reconditioned modules, with the black metal bars on top. I was thinking this would save me quite some time. Not much.

Last night I took the old battery out.
This morning was going to be the big day.
- Took the old modules out of the case
- Had to unscrew a whole bunch of bolts
- Most bolts had grey-green acid powder on them. Tried to clean them (with a brush).
- Put the refurbished modules into the case
- While screwing the bolts back on, one of the bolts went in sideway (?) and stripped the screw. We're talking here 5 degrees max.
- Tried the bolt on another battery by being stupid ... and mangled that screw too.
- Threads on both battery look bad
- Another module was already mangled so I'm out three bolts.

I was thinking perhaps I could fix this with some washers. If I'm lucky.

Or should I instead take some modules from my old battery and replace them?

Any suggestions?

 

I'm going to need 3-4 extra bolts to attach the battery module. Do you know where I can buy some?

 

Thank you so much for the comment!
I didn't update this page a lot lately; I've been up and down thinking "I can fix this!" and "It's hopeless". I'm a few weeks away from finding those mood swings funny
The good news is I read a lot and I'm waiting for an RC charger tomorrow so I can properly identify which cell are worth keeping and which are not.
What I can also tell you is that this issue has really brought up all the gremlins in my life; you wouldn't believe the mishaps and deceptions I've had, both around the car and real life (c)(r) since the dreaded red triangle. But you know what they say : what doesn't kill you makes you stronger. Since I'm still alive it means I'm somehow stronger LOL
Hopefully when all of this is done I'm hoping my car's hybrid battery will be too.

 

UPDATE : So I'm still working on my battery pack.
Got my RC charger. Took a while to understand how it works - the menu system is anything but straightforward.
Load tested all the battery modules with a Prius's headlight bulb. Boy that was long! Got time to get to 7,5v, 7,2v, 7v, 6,8v and 6,5v
One module is bad and will drop to 6,6v no matter how much I charge it. As soon as I put a load on it it just drops off. I'm pretty sure this is the source of my red triangle.
I have 7 other modules that will last less than 2 minutes from 6,8v to 6,5v. I'm going to swap them too.
The rest goes from OK to really nice.

Now one question before I start putting everything back together.
In the course of my previous attempt, I had to take my two battery packs apart. Forgot to check what polarity was on which side.
On the ECU side, presently I have the positive where there is the single connector (see image).

I'm assuming that's right and I'm also assuming getting it wrong is NOT going to help.

If someone could please confirm that would be great.

 

Thanks!
Would hate to have the wrong polarity when the whole thing is running 100+ amps ... no smoke of doom please LOL

 

GOOD NEWS! I finally got the old car to start! It's ALIVE!
I have to tell you this project didn't go well at all. Today I wanted to put back the headlight (because with a missing headlight bulb - wouldn't you know it - the car doesn't go to Ready). I dropped the bulb inside the car while trying to fit it in (...).
An hour and a half later I finally found it and the car started as soon as that bulb was installed and the circuit closed.

THERE IS ONLY ONE ISSUE LEFT
Now when I drive the car, the charge meter for the hybrid battery will only go up three bars. The bars are in blue (two bars and it's purple)
Everything else works. There's no codes.
- I've only driven it for about 5 minutes so far
- Two of the bolts on the modules aren't the original Toyota stock but generic store bought bolts
- I did a boo-boo; when I cleaned the busbars I also put the original toyota bolts in the mix and it took off the zinc plating I think.
- I'm going to put some gas in the car - I know there's at least two bars left but the car has a blinking bar.
- I picked the best modules out of two sets. Pretty sure they're all good.

I will get a whole set of NEW bolts ASAP.
Do you think the battery just needs to adapt and will get back to normal?
Do you think the bolts are an issue? I've tested them and they seem to conduct just fine.

Thanks again.

 

Thanks for the question.
The brutal truth is I don't have a torque wrench. I work with very limited funds.
Also the two replacement #5 nuts I've used are not nearly as good as the original nuts. In fact they're crap. I'm trying to get a car parts store to source me some.
I'm assuming if I had proper replacement nuts that couldn't hurt.
