Huh?
What does this even mean???
It’s a battery. How do you ‘kill’ a car or motorcycle battery, or wear out your phone or laptop battery, and how to keep them alive longer? Same deal.
Anyway the original article is valid. It’s like the sleazy used car guy and the “only owned by a grandma who took it shopping on Saturdays” except in current tech you can’t do a rebuild on a EV battery and be good as new. The cost to replace is more than it’s worth.
Maybe someday, but look at phones, right? Batteries for phones became viable and then makers sealed them right back in ‘for protection’ but mostly so you don’t go keeping your old iPhone 6 or Galaxy 4 alive and realize that you don’t need a new brick and contract :)
