The Nissan LEAF Battery Conundrum: 70%, 80%, or 100%? What to do? What would you do?
Many reputable news sources recently reported Nissan is retroactively extending the battery warranty on certain model year LEAFs. I share here* Autoweek's article which reports on how Nissan with the new extended warranty will replace batteries less than 5 years old or with less than 60K miles if they fail to charge to 70% [I chose the Autoweek* article solely because it was the first/top article to appear during my Google search of the topic].
Here is where I start to get a little confused and the conundrum deepens:
- Nissan now says they will replace batteries that fail to meet the aforementioned criteria.
- My 2012 LEAF lease is 24 months.
- Nissan recommends in their 2012 Nissan LEAF Owner's Manual [I have the Manual because I own a LEAF (Yeah!!!!)] no more than 80% charge for maximum battery life, and they make the distinction between Long Distance Mode vs. Long Life Mode (Manual page CH-20**).
- 80% charge gives me an 84 mile range, and a 100% charge gives me a 102 mile range.
- My furthest single trip in my LEAF has been 60 miles.
Should I charge my batteries to 100% for the next 23 months and enjoy extended range (or more climate control and/or aggressive driving)? Or, should I only charge to 80%, always drive in ECO Mode, and preserve the life of the batteries that can otherwise be replaced under the new extended warranty? [and likely well after my lease expires and I am driving a 2014 LEAF??]
An ethical questions? Perhaps. Maybe not? What to do? What to do?
What would you do?
