with a 5-year warranty on the battery maintaining "approximately 70% of battery capacity", I should be covered, right?
As my car approached the 5-year expiration date, with 22,000 miles on the odometer, the car was charging to approx. 62 miles - well short of 70% of its original 102-mile range.
After purchasing the Leaf Spy app (which plugs directly into the car's maintenance port) I discovered the car had 64.8% of battery capacity remaining (182 GIDs). So I went back to Nissan Service and showed them their bar display was wrong - remaining capacity was well below 70% - and demanded the new $5,500 battery to which I was entitled. "But it's not below 9 bars," I was told. So I demanded to talk to the Service Manager. "But it's not below 9 bars," he said.
In two consecutive calls to Nissan America Customer Service I tried to explain. "Because your 'bars' don't correspond to any physical property they're useless to consumers for evaluation purposes," I said. "I purchased the car based on the battery's capacity not falling 'below approximately 70%' of original capacity." Both times I was told, "But it's not below 9 bars."
Original EPA range rating of '11 and '12 Leaf was 73 miles. See https://www.fueleconomy.gov/feg/Find.do ... s&id=30979. Guess-o-meter values are worthless.
Yes, the way the capacity warranty is warranted is in bars (viewtopic.php?f=4&t=13192). Full stop.
As for battery gids or SOH or whatever, Nissan has never released any public documentation on those along w/any caveats (e.g. conditions required for the readings to be accurate, how many watt-hours each gid can represent, etc.) See posts like these from the Leaf Spy auithor: viewtopic.php?p=516444#p516444 and viewtopic.php?p=521773#p521773.
It needs to be below 9 bars before expiration, otherwise they'll tell you to pound sand.
Regarding the last bolded part, when you bought the car in 2011, there was NO warranty at all for gradual capacity loss.
