Ideal charging pattern for longest battery life

Ideal charging pattern for longest battery life

I suspect this might have been covered before (no search). What is the "ideal" method for charging.

I have read that the more we do a "full charge" (letting the batteries get very low), the more life we take out of the batteries. But does this mean that the ideal method is to top them off whenever possible?
I have the ability to charge at work, and of course I can charge at home...should I do both?

Also, is it better "ideally" to charge at 110 vs 240? If I have driven only 50 miles, I can easily get a full charge at 110 over night.

I also wonder, if I really would benefit from topping off the battery every night. For instance, yesterday I drove 170 miles, ended the day with about 70 miles and gave it a standard charge last night. Today, I drove about 16 miles, is there some benefit to plugging in tonight? How about if I drive another 16 miles tomorrow? It is easy enough to pop the charge cord in but is there a benefit? Is there actually a benefit to leaving the battery at 80%, 70% etc. What is the ideal regimen? I would like to know.

I was told by Tesla rep that even when you have 220 miles left, it's good to charge it full

Well according to the manual, plugging in whenever you are not driving the car is ideal, so yes, it seems like it would be a good thing to charge while at work and at home.

However, at work, if you have to use a paid charging station, then I would assume that the cost/benefit is probably not worth it as the electricity will be much more expensive.

The car is designed with the primary scenario of doing a normalish commute during the day and plugging in when you get home as being the daily routine, so I have to imagine that skipping the charge at the office will not really be that big of a deal.
