1 Year "Battery Check" Results

Wed Jan 04, 2012 7:34 pm

I'm starting this thread to discuss our experiences with the LEAF one-year battery check. Owners, check your Warranty booklet to see that the first two yearly battery checks should be performed by your dealer without cost to you. (MODS - if I missed another similar thread in my search, please move/merge this one, thanks.)

We will have had our LEAF for one year next week. I decided to get the one year battery check done today. The results are not what I expected. I expected to get a sheet that outlines the state of each battery cell. Details. With numbers.

Instead, I received a "Battery Information Sheet" that contains two main parts. At the top, it states, "The battery capacity retrieved from your LEAF is as follows..." then there is a box with 12 filled-in blocks. In a generic way, it tells me that my LEAF battery has not degraded to the point where it would lose 1/12th (or, take away one of the marks).

Below this is a section called, "Advice for your usage" where four items are listed. These are -
1. Frequent use of quick charging
2. Frequent charging when battery state of charge is already high
3. Too much electric consumption while driving, and
4. Long term parking with high state of charge.

The "Recommendation" for each of the four items is, "Your score is very high and good for your battery."

That's it. That's my one year battery check. I guess I'm golden.

Oh, the tech also caught one code, DTC code B29A0, "N/Chg Port Engagement Error (Signal Invalid)" The tech ran details on this and said not to worry, that nothing was found to show that this was a real problem. By the way, he asked me if I used the upgraded EVSE to charge at 240 volt. I replied, yes to this and he said this may be what was caught in the error code. But, don't worry, all is well.

Thanks for the heads up; good to know you're still 12/12 after a year.

But, darn. I was looking forward to obsessing over every cell! :| :lol:


How many miles do you have?
I noticed you're still working with polymers.

Did your Leaf firmware get updated during the Battery Check or had your Leaf been updated before?

My Leaf is still on the firmware that it was shipped with and I am not to keen on how the new firmware will change the behavior of the SOC.

Thanks for the heads up. Mine's due in a few days as well.
Did you need to drop it off for the day?
Did you go in with an especially low or high SOC?

I set up an appointment and told them that I had only 2 hours to get this done. They finished it in about 1 hour. It was at about 75% SOC and they didn't seem to see SOC on arrival as an issue. Also, they had it on the charger while they did the check.

I will be getting mine done in a couple weeks. the lack of specific information is a bummer. so it sounds like until we get eight and half percent battery degradation or not I know anything
