Often when getting an answer how long a battery will survive you get the answer how many loading cycles it will survive. But, what is a charging cycle? From 0 to 100% or also from 80 to 100%? My guess would be, that you have to sum it up. But how does regeneration affect the life span? Is it like a little loading cycle which reduces the lifespan? So, would the battery live longer if you could switch regeneration of and use it only on longer trips where you would longer range?
