Nice article, thanks for the link :) I solidifies what we're talking about. The bottom line is that all Cmax batteries are going to degrade over time, but you hope that yours can degrade a little less than others via best practices. So what can you do?
a) Even though you can drive faster (up to 4 bars on battery), limit the discharge of the battery to 2 bars or less.
b) Do not leave the battery fully charged at 4.1v all the time, best to charge ready on departure when you need the full capacity.
c) Supercharging (Tm: GG) while may give you an extra mile of range is not good for the batteries.
d) Try to keep the battery cool and not heat soak the car as much as possible (park in the shade or a garage whenever possible).
e) Hover the battery around 60% charge when the car is not in use, and don't always charge to 100% unless you need it.
f) If you do charge up to 100%, combine smaller trips to use the battery charge before recharging instead of charging back to 100% after every use.
g) When draining the battery, try not to go below 20% charge level if possible. Sometimes you need it, but its best not to drain it all the way (even though I've been guilty of that on several occasions in the past), meaning don't dig into the hybrid battery more than necessary. At 0% HVB 100% hybrid battery you are at 21.5% charge level.
I may have forgotten something besides the points above that came to mind.
