Dell Power Manager - Primarily AC use or Custom (50%-60%)?

Help

Which should I use? I've been using custom for a while but found out that 'Primarily AC use' charges to 85% and then starts using power from the adapter instead. I want to know which one will be more beneficial to my battery's lifespan in the long run.

I'm a bit paranoid after having my old laptop's battery bloat up after a year and a half of use.

So which do you prefer / use?

EDIT: I mainly use it as a desktop but need to bring it around sometimes but not as often.

I set a custom plan for my XPS 17 9700: It starts charging when the battery is at or below 60% and stop at 85%. This still nets great battery life and should hopefully go a long way toward preserving its overall health.

In my XPS 15 9570 I have it in "Primary AC use" and there's also a different setting for "charge percentage" which I have at 95%. These are bios settings (I'm not using using windows), and after 2.5 years my battery is still at 0% wear.
