I’ve posted this before but I have more info now and a little more knowledge. First I purchased a non running 2014 Volt with everything dead that had been sitting for almost 2 years. I started my journey of getting the car roadworthy by first replacing the 12 volt AGM battery and figuring out reprogramming the remotes, windows and rear hatch. Once that was done I purchased a Innova 5410 OBD2 to figure out other problems. Codes retrieved are P0D17, P0B3D, P0AFA, P0ABC and P0AOC. Most if not all have something to do with low voltage. I did a scan on the HV battery and cell 1 has 0.0 voltage, Cell 8 has 3.0 and cell 10 has 3.5 volts. The rest all the way thru 96 cells have 3.8 with a few having 3.7. I presume the number one is the problem and how do I go about repairing or diagnosing the issue of it being that one cell? Also the car will not take a charge, on startup the message on the cluster comes up NOT ABLE TO CHARGE. Gas fuel gauge is at half full and battery range is at 0. Thanks for the input.

Individual cells can't be replaced as they are welded in. Some claim it's theoretically possible but none have done it.

You could change out the battery Module the dead/bad cell is located in, or you could replace the Section (a block of several Modules).

Not sure how it could be done, but if you could find a way to apply 400v DC to the battery for a few minutes, it might get the battery to the point where Volt's computer would charge it.

Absolutely not.

NiCad and Nickle Metal Hydride batteries can be zapped back to life with high current (when they have sat dead for a year).

Lithium Ion batteries that have gone completely dead from not being charged are very likely to burst into flames if you apply a charging voltage to them.

That is why these battery packs have monitors on each bank or cell, to keep the cell from being hit with any voltage if they have gone to 0V, and in some vehicles to by-pass a dead cell permanently to allow the vehicle to still function.

If you were going to attempt that you would have to take the cell or bank out of the car and out of the pack anyway. Why go thru all that work to risk it catching fire immediately, or 3 days after you put it back in the car?

Your best bet would be to take it to the dealer and have the battery section with cell 0 replaced, or find a used functional battery pack from a 2014 or 2015 if you feel you have the ability to drop and replace the battery pack on your own. The last option could be less expensive, but has the risk of the used battery having issues of its own. I wouldn't recommend the second option unless you have a healthy respect for the 400V contained within the battery and Class 00 (750VDC) safety gloves.

There is NO way to replace 1 bad cell. Get a "verified battery" from a specialty house while they are still available. There are three sections to the battery; they replace the bad one(s) and give a few year guarantee.
