In practical terms, we've had our 2013 Leaf since 2015, or about 6.5 years. It's been plugged in at home every night (well, except for a couple that we forgot), and gets used 3-4 days a week at minimum. So it's had around 1,200 charge cycles with no noticeable loss of charge. Only a couple of those charge cycles were deep discharges. My understanding is that deep discharges and fast charging are harder on batteries than light uses with slow recharges.Not necessarily. Generalisations are just too general. Some cell constructions and chemistries effectively integrate the amount of charge/discharge over the life of the battery and can result in a very short service life for a battery. Gel cell lead acid batteries is one that comes to mind. They have a cycle life of about 500, up to 1000 if you are lucky, but if you use a crude charger that results in charge-discharge ripple it very quickly kills the battery. I am sure there are others as well, but I hope you get my point.
The generalisation also doesn't make sense from a logic point of view. If you discharge to 90% then recharge does it count as a cycle? 80% etc. What defines a "cycle".
