30 miles left on my battery warranty

[pickleking]

Hey guys. I’m coming to an end of my battery warranty so I decided to do a 100% charge to verify that the battery is ok. What advice do you guys have for me based on what I’m seeing.


Before the 100% charge my battery imbalance was 22mv. After charging to 100% the imbalance increased to 40mv. I then took the car for a long drive where it’s currently now sitting in my garage with 6% SOC and showing a 122mv imbalance. My plan is to let it sit at 6% for a few hours than charge it back up to 100% and let it sit there for a few hours to see if the mv imbalance comes down.

Is that plan logical? Or what should I do with the car as the battery is looking really imbalanced to me.

Hi, As I already wrote here Acceptable cell imbalance range? in my case I have to charge the care at first time to 100% and live unplugged, to trigger the balancing process. After that I have to charge the car not later than at 70% SOC to stay in balancing process. I takes day to go down from 50mv to one digit imbalance. But in my case I have only one cell which has this problem, I your situation there are multiple cells, But you can give it a try and write here back your results.

I have also same situation: after charging to 100% the imbalance increases from 17mv to 30mv. I will be tomorrow at about 10% SOC and will report my imbalance!

I will be tomorrow at about 10% SOC and will report my imbalance!

Today was the imbalance at about 16mv at 20% SOC.
