Repeated Battery Dead Cell

Recommended Posts

I bought a 2013 MKZ just over two years ago. The battery has been dying with a dead cell every year. I just had it happen for the third time. With a dead cell you cannot even jump start it, it needs to be replaced. I have been able to get it replaced under warranty each time so cost isn't an issue (yet) but it is very inconvenient for your battery to die completely randomly and no way to drive until it is replaced. I asked the guy at the auto parts shop what causes dead cells and he said it is very rare and even said "one in a million" batteries will just get this problem. Considering I've had 3 batteries die from a dead cell in just over 2 years, I'm thinking the car must be causing this problem. Anyone else seen this problem or have any idea what could be causing it?

There is virtually nothing in a car's system that could cause a "dead cell" in a battery. It is cause by an internal breakdown inside the battery.

You do not mention what brand of "auto part shop" battery you are using but after 3 times I would certainly consider another brand or a different shop.

The first time it happened to the battery that was in the car when I bought it. The next two time it happened to batteries from O'Reilly Auto Parts, and it was not a cheap battery but I don't remember the specifics.

So you're saying that a car cannot provide conditions to a battery that make it more likely for a dead cell to occur?

Hi aceuvspades. You can wait out the warranty period on your current battery and keep replacing it with the same brand if you wish. However, I would recommend you install a Motorcraft (or other top end, name brand battery). You can find coupons for a Motorcraft battery purchase on the Ford Owners website.

Sounds like good advice. Hopefully the Motorcraft will do me better. Thanks.

That is correct.... think of it this way

A battery of a typical car today is made up of 6 cells that form the battery. The cells of these batteries each produce a specific voltage and are connected in series to obtain the desired total voltage (nominally 12 volts). There is no direct connection from the individual cells of the battery to the car to make one cell go bad.

On the other hand a dead battery vs. a dead cell can certainly be the result of something in the car causing the battery to drain all cells of the battery. There are other factors that will affect the expected useful life of a battery.

Hi aceuvspades.  One additional bit of information, in case you haven't heard or read it here before: With all the computers and electronics nowadays, cars are very battery intensive. So a battery life of 3 years is about what can be expected (although 1 year was ridiculously short).  It's not like the "old days" of stretching to 6-7 years or more. Will some people get lucky and get longer life and will you hear those stories? Yes, we all hear those stories.  But expect 3 years viable battery life. Anything more than that, consider yourself lucky.

Good luck and keep us updated.
