By default my Tesla Roadster charges to 80% and gives me a warning if I charge beyond that level. When not in use my car sits at 80% in the garage and I only top it up to 100% as I'm about to leave home (i.e. it doesn't sit at 100% charge for any length of time).
I do a lot of long distance travel charging to 100% and after 52,000 miles and 46 months my Tesla has lost ~10 miles range (~5%). I suspect that battery chemistry and battery heating/cooling promote long life but we'll have to wait 10 years to find out
Jack Rickard (EVTV) is extremely knowledgable in this area and he has long argued that the chemistry in the Nissan/Renault packs will not provide a long term solution. Personally, I think this is ok now they have a warranty.
Plug In America have published some great battery surveys (here).
