Reports from Arizona on battery degradation are quite alarming.   Folks out there have lost up to 3 capacity bars.    Nissan is beginning tests next week.

My rule of thumb is to not charge if the battery temperature gauge (left side of dash) shows more than 6 bars (battery temperature higher than 98 degrees, iirc).    This usually happens on hot summer days between 2 and 8 pm.  Another rule i follow is to not leave the car at high SOC during these hours (20 to 70% seems an acceptable range).

Babying the battery this way is painful.   But we are awaiting Nissan's contingency plans.

 

Best to everyone,
