Re: Has anyone seen so much degradation in a month

Be interesting to see your Leaf Spy cell plot when you totally drain the battery. I usually have 130 mv plus deltas at that point. It will show the weakest cells.

Most recent - essentially total discharge. Have not done this recently, so might be even worse:

The car is currently at Nissan for the recall and I have requested a battery check. The service advisor told me there is degradation which I told him I am aware of. However he also said the battery is discharging fast and the tech is still looking at it. Let's see what they say. Worst case I am out $130 diagnostic fees
