In short, battery health/life can be improved by doing these things:
* Don't charge when the pack is hot if possible, according to the battery temp gauge. Anything in the upper* or rightmost 1/3 of the gauge is "hot." If you have to charge, don't do it with DC Fast Charge, aka "QC."
* Don't leave the car sitting with more than 70% or so charge. If you need the full range, charge it to 100% with the charge timed to end shortly before you leave.
* Keep the state of charge (SOC) between 25% and 75% when possible. If this means charging once every few days instead of every day, that's fine.
* 7 temperature "bars" or more on the Gen I Leaf is hot. If your climate allows you to avoid 6 temp bars as well, that's even better.
