Varies a huge amount. I have an 8 year old tesla s 85kwh battery with 65k miles on it, known to be above average, 5 miles lost from ~272 range. Tesla has the best results for long life, it's basic matter of heating and cooling the battery. Cars without that have significant battery degredation when supercharging/fast charging because the battery gets hot. The worst is the leaf, almost every recent car except that has batt. mgmg. system. You also heat and cool battery when driving.
