It's an added charge cycle on the battery. A guy in San Diego does full EIS and more for EV cells. His data shows multiple shorter recharge cycles wear the battery down faster, no matter what range you try restricting the recharging to. Same data shows that the batteries are better when conditioned harder on their first charge, gaining much better cycle performance and count, at a minimal sacrifice of capacity.

And this exact same thing coincides DIRECTLY with my lithium-powered portable lighting, so I'm pretty up-to-date on very top-level research, because I hire this same person.

His name is Luke. You'll see him all over the globe doing lithium EV research and testing.
