Tony, I don't understand your requirement to lose five bars before warranty kicks in. Andy Palmer said:
----------
"Under an expanded New Electric Vehicle Limited Warranty, Nissan will protect against capacity loss in LEAF batteries that fall below nine bars, of the available 12 bars displayed on the vehicle’s battery capacity gauge, for the first five years or 60,000 miles in the United States, whichever comes first. For LEAF vehicles whose batteries have fallen below nine bars during this period, Nissan will repair or replace the battery under warranty with a new or remanufactured battery to restore capacity at or above a minimum of nine bars."

To me, that clearly indicates that loss of four bars (eight remaining) would trigger warranty coverage. Let's not make the requirements tougher than they really are... I expect to use that warranty.
