Table 2: Cycle life as a function of
depth of discharge.* A partial discharge reduces stress and prolongs battery life, so does a partial charge. Elevated temperature and high currents also affect cycle life.
Note: 100% DoD is a full cycle; 10% is very brief. Cycling in mid-state-of-charge would have best longevity.

I've had 2 previous Leafs and currently have a 2020. I've ALWAYS simply plugged them in just about every night to a level 2 charge station. I've never lost even 1 bar on the battery capability scale.

The bolded "advice" is terrible and should be ignored. There is 0 evidence to suggest that li-ion batteries like being at high SoC esp. for extended periods of time.ridera2 said:Disregard the charging to 75%; it's nonsense.

This person in a SUPER MILD climate was down 6 capacity bars on their '13 Leaf a year ago: https://mynissanleaf.com/viewtopic.php?f=9&t=31297&p=587653. They had a crap chemistry but I suspect if they took better care of their battery, they'd have been down only 3 or 4 bars by that point in time.NISSAN recommends you use the following
driving and charging habits, where possible, to
help maximize the battery’s useful life:
...
Avoid exceeding 70-80% state of charge
when using frequent (more than once per
week) public Fast Charge or Quick Charging.
Allow the battery charge to be below at least
80% before charging
...
NISSAN recommends charging the batteries
using the long life mode unless the
vehicle is going to be driven a long distance.
See “Charging timer” in the “CH. Charging”
section.
Notice it says "Lithium-ion suffers from stress when exposed to heat, so does keeping a cell at a high charge voltage." OP can also look at "Table 3 demonstrates capacity loss as a function of temperature and SoC."ridera2 said:Go here to learn the facts about charging lithium_based_batteries:
