Augh!! P3000, P0A80, P3021, C1259 on an '07

I just did a full battery reconditioning on the wife's '07 (118,000 miles) using the Prolong charger. I've done this several times with all three Gen 2 Prii we've had. Never a problem.

I took it out for a test drive and it looked great for about five minutes and then the battery monitor went into yo-yo mode. Soon got the red triangle of death and other lights.

Checked with techstream and got the codes listed above. I cleared the codes, left techstream connected and monitored while taking a short drive of less than a mile. No more red triangle or any other warning lights, but block 11 voltage is making wild voltage swings and the battery fan is on red alert. All internal resistances are identical at 0.019 ohms.

I think I'll see if @TampaPrius.com can help me out tomorrow. For now, I think I'll see if I can enjoy the rest of the holiday. Can't afford a new battery now. Hoping a replacement block will buy time. Stay safe, my friends.

 

Yes. It was full and firmly pack with electrons. Charger was at 240V for several hours on the before reconditioning charge.

It's 95 degrees outside right now, so I'm not real eager to dive in, but with those tips, I'm tempted. I have most of the stuff already out of the way because I was going to take to to Todd in the morning. Now you have me thinking. Thanks, Eric. By the way, there is magic marker writing on the battery which makes it look like it's been worked on in some fashion before. Doesn't say what was done, just that it was ready to install.

I'll let you know what develops.

 

Uh oh!! What was I thinking? <face palm!> I know I was supposed to let it set at least a half hour, but I think it was only maybe 5 minutes. Do you think that made a temporary situation or maybe really did damage block 11?

We were in a hurry to get started on a trip in the PiP.

 

I've never had an issue either. I have a feeling I shot myself in the foot, trying to do the test drive before we went on our nano-vacation. Shooda waited till we got home, but thought we might be gone longer.

I took it for another spin just now. It went longer before failing and block 11 didn't make as wild of swings as before, but it finally popped up with a P3021. I sent Todd at Tampa Hybrids an email via his web site to give him the codes and a heads up that I'll limp in his direction in the morning. Maybe I'll get to see a world class hybrid surgeon at work.

 

No, it's still in the car. From what I've seen, you can fix it in the car, but it looks like it would kill your back. Todd should have the modules, so it's probably a lot faster to take it there. Wife will use my car tomorrow morning, to take a friend to the doctor. Then she can come get me if I need a ride home so I can go to work Wednesday. I need to make an appearance at the office now and then so I can keep getting paid. LOL! If I had modules, I'd be game, but I kind of need to get this fixed fairly quickly. But can't spend a ton either. It's awkward timing right now.

 

Good advice. It's actually not that I didn't want to wait; I just got cocky because I've done it several time and forgot that I needed to wait because I was working from memory other than a print I made of the discharge steps and levels and the bulb change points.

I don't think I discharged deeply enough to reverse a cell. I didn't have time Sunday morning to go clear to 17 volts before we had to leave. So I stopped at 29 volts. All the other discharges were to spec. I probably did it by overcharging on startup. And yes, at this age, it was likely already on its way out. I just made it die sooner.

 

Apparently more than you already have.

Battery's all unhooked and ready to come out except for the last 3 or 4 bolts. Tomorrow, the fun begins.

In the morning, I'll see if Todd can help me for a price I can afford and if he has the part I need. He's expecting me. If not, I'll be reaching out to @ericbecky to see if he can send me the part.
