Otoh, that 12% extra useable I can get doesn't offer any advantages except a wee bit of extra range and didn't seem to measurably reduce cell life much in an early Volt pack. Have 11 years use on it, 16,000 city miles, will advise when they do fail.

Manufacturers have been steady removing reserve battery capacity. 95% is pretty typical today. That is a far cry from the 25 - 30% some of the early EVs had. (Of course they also tell owners not to charge to 100% on a regular basis)
My Bolt has 10% in reserve - 5% at the top and 5% at the bottom of the SOC.
