8. Leaf batteries degrade over time - some of them quickly!

Any necessary range calculation must include loss of battery capacity over time. This ranges from 'rapid and substantial' for the 24kwh Canary pack, to 'Generally reasonable in moderate climates' for the 4/2013 through 2014 Wolf pack' and 'Very reasonable in moderate and warm (but NOT Hot) climates' for the 2015 Lizard pack. The 2016-2017 packs are discussed above, while the 2018 40kwh pack is, at this early juncture, showing more degradation than either the Wolf or Lizard packs, unfortunately. Depending on your local climate, and on which pack it has, factor in degradation ranging from a best case of about 3% per year, to about 15% for the more fragile packs or a Hot climate. What about a Canary pack in a HOT climate like Arizona? Please don't even consider it.

 

One thing I found was no matter what you do, the battery is going to degrade over time, so that is normal, so try to get a used leaf with the most bars (10+)
