It did not, nor it does today. In fact, one should always start with max fill so as to minimize the depth of discharge at the end of the run before refill. Now, THAT protects the battery. In other words, full discharge and recharge over and over is detrimental to the battery life in the long run more than anything else.
I faithfully used the 80% setting on my 2013 LEAF and think the battery degradation was not too bad. Presently at 10 bars, 48.1 AHr, 73.6% SOH at 61K miles, 5yr 10 mo. old. I understand that my early 2013 has the 2011/12 battery chemistry and is not very good on degradation compared to some of the later LEAFs.
Hopefully, someday soon there will be more real world data on the optimum charging strategy. For now, the overwhelming consensus supports using the slider. I think the Hill Top Reserve Mode was a wink-wink-nod-nod battery preservation mode, to avoid Nissan unfortunate mistake with the 80% mode. I don't think Chevy is being responsible in avoiding the topic of battery preservation techniques.
I noticed an interesting effect in the LEAF. I usually kept the battery between 50 and 80%. When I had noticeable degradation, the SOC seemed to have the most capacity loss in that part of the SOC range. For that reason, I am trying to avoid repeating that effect while still avoiding the SOC extremes in daily driving.
I may be like the nuts that change their oil every 3K miles or so, but at least I don't have to climb under the car to do it
