On the 30 KWH battery, the twelfth bar doesn't disappear until you hit 80% SOH. Of course that was before Nissan did the LBC firmware update. Now we will have to wait for new reports of lost bars. Until Nissan details the change or we get sufficient data to empirically map the battery loss, all bets on when the capacity bars disappear are off. Nissan probably didn't change the mapping but there's no way to be sure at this point. The same goes for warranty replacement of the battery. It will take a couple of years to collect enough data points map the degradation of the battery with the new firmware. While I hope that the battery failures so far were the result of software errors and that my new battery will last 6 years, I ain't holding my breath.
