Default Bad block cell 19


here is bad block

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.

Default Duct work on hybrid battery. ....


sorry I forgot to mention before when you doing your battery reincarnation please do CLEAN DUCT LINES AND TAKE BLOWER MOTOR MOUNTED ON TOP OF BATTERY AND CLEAN FINS ONE BY ONE.
WE HAVE USED BRAKE CLEANER BUT VERY CAREFULLY TO NOT DAMAGE OF FLOOD ELECTRIC COMPONENT IN IT.
JUST BE CAREFUL..

REMEBER IF DUCT IS FULL OF DUST THAN YOU BATTERY CANT COOL DOWN AND WILL OVERHEAT.

anyway that was just one more reminder at the end.

Cheers.

Nice write up.

224k miles on my original traction battery, I have to reset code every 100 miles.

I intend to have it rebuilt at 250 or 260k miles.
