I was the same way, as that's what I got from the User Manual. It seemed like the self discharge function would protect your batteries, but as I found out, my oldest batteries are the ones with low Battery Capacity and the ones that caused 2 "Fall from Sky" events.
I also have found that when charging if I charge until you have 3 solid and the 4th light starts to blink I am right around 65%.
I have added bimonthly battery maintenance in the form of topping them off to 65%, and since then my batteries' health has been good, with my newer batteries still having 100% Battery Capacity.
The great members of this forum educated me and have kept my Anafi in the sky where it belongs.
