And remember that the seat covers can be removed and are machine washable. You'll need a set of hog-ring pliers and hog rings ($5 off ebay) to reattach them.
Well? We are back from our holiday vacation and I went to work on cleaning up the interior of the car. The cleaning isn't as thorough as I would like but other than a slight lingering vinegar smell it isn't too bad. I have not had a chance to open up the hybrid battery compartment yet but I had to use the car today. At first I thought I would just keep the clutch switch (calpod switch) on thereby eliminating any assist or regen but I figured if the pack is bad I'll just let it do what it wants to do and see what happens. (sorry Ron)
Starting from 19bar SOC I was able to get full assist and regen events. Furthermore I was able to use manual assist (4 bars) to the point where the SOC gradually ticked down (not a negative recal) to 3 bars. After using assist all the way up to the garage I parked and checked the voltage with a DVM and it read 152? Geez, I think this thing works better than before the meltdown!
I think I got lucky. There is no doubt that there was damage done to the pack but I would have though the IMA light would have gone on or at least a negative recal at half SOC. If I had a heated garage, I would probably deal with this in more detail but for now I think I'll give it a good balance charge and keep my eye on things.

As I understand it, you have the buddy pack removed?. (The one that fried)

Yes, that is correct. When things were still warm (after the meltdown) the DVM said 14 volts. After cooling off 120 something. After a grid charge to 169 it stays at 163 after 30 minutes. After 60 miles of driving today (40 without using MIMA) I had full assist and regen events (according to the display). The SOC stayed at 17, 18, 19 bars. The last 20 miles today I used 4 bars of assist (6 to 8 amps) most of the time and the SOC slowly went to 3 bars. After parking the DVM said 152. I'm sure the pack dipped quite a bit during heavy assist but no negative recal.

It's YOUR battery, not mine. Just remember that if you do have any good sticks in there, the bad ones will drag the battery out of balance and start damaging the good ones.

Eli, the sticks got hot enough to melt the case. There is no way they didn't vent. Vented cells aren't always toast, but they are always damaged and run at reduced capacity.
The problem is that they still put out full amperage (for less time), so they trick people into thinking they are good.

As long as no venting occurs, they seem to come back quite strong, and as balanced as you're ever going to get them.

The paralleled pack is the one that melted the case. I'd be surprised if there was a single un-vented cell in that pack, agreed.
The pack he's currently talking about is the one that discharged into the melted pack, and thus was only at 14V after the event.
The pack remained cool, but the concern is venting due to the obviously reversed cells...
At low enough rates and given a short enough time, the cells won't vent due to reversal. I was at first assuming that the discharge into the melting down pack could have been fairly brisk, but maybe it wasn't.

Oh, that one. Yes, it probably reversed, but at low amperage it might not vent. 14V / 120 cells pretty much guarantees that some cells reversed unless the pack was pristine.
