After double check all connection it's time to start a car. If you don't have any warrning light that mean u did good job and heat sensor is working. Enjoy and save money on hybrid aux battery. Remember this just for educational purposes only. After couple days my reading on cca was 1015

Here was tricky part.after resetting code all battery cells appears normal .this is live data shot. So we had no choice than do one more test just to be on safe side.

Second test came up with extra code p0a7f So now we were sure that bad block was block 19.

Now was time for rebuilding battery pack.Donor was Toyota Camry 2008 .and those cells were sitting at room temperature about 4 years.i was thinking no life in them,but I was blown away after I recharged them.great cells.

I took one by one and measure voltage .it was about 6.8 to 7.2 v. But remember here voltage does not mean that cell is good or bad.next step was charging.

Used this simple charger .I put on 2 amp. Range and was monitoring voltage. Idea was to bring cells up from sleeping mode after 4 years.

Shortly after I have reached voltage I like. Just one side note here.when you dismount your hybrid battery and disconnect all busbars voltage on most cells was about 8.0-8.2 volts.so that is reason why I was charging new donor cells up to 8volts.

This was state of charge after charging was done. Slightly less than 8 volts but I was ok with this.

I was blown away with this measurements . Some cells were from 6.8 to 7.4 volts.

We strated with charging precedure. We have used simple car charger using 2 amp.range for about short time untill we brought cell to about 8.0 volts. Reason for that is the cells from originall battery pack when you pullout from car will have about 8.2 volt most of cells ,so I was trying to bring new cells to about same 8.0volt range.

Shortly after this was voltage I was happy with. But remember this here is for education purposes only . It may not work on some other cells if they are to much discharged.

After charging was done this is voltage we had. But still remember this does not tell you if cell is good or bad. This time we were gambling.and hoping for best.

Here it is my lovely battery pack that made over 500 000 km As you can see there is a lot of donors cells from different cars Prius,Altima Nissan hybrid,Camry hybrid 2011,2009 and now will be 2008 donor Camry. All of them are compatible.

Here is cell 19 actually block 19. I have marked down numbers of blocks for easy diagnostic later on. So in my case block 20 is first from driver side and block one is first from passenger side if you looking from back of car. In other cases could be oder order around.

Here was big problem .never use battery gun to increase speed of rebuilding batteries .durring basbur removal one of washers was Cris threaded and we got problem. In case of this problem u can't solve it with making new thread ,will not work in our case .so I had to replace that cell too ,even if cell was ok I had no choice.

After procedure of replacing bad cells with new used one was done we used some tape to keep all busbars covers attached to battery .

The rest of used donor cells we have recharged and put in box for the future ,just in case if we need to replace another cell. Now we will see how many miles we can do per one tank.

Here is one more confirmation that block 19 was bad. So do not let dealer or some untrasty mechanic pull wool over your eyes,with some lame explanation about Hybrid Codes. Really only thing you do is replace bad cell and keep driving.
