I realize I'm not answering your question, but I have two batteries
for my Nikon dslr. I'll never know how long a battery will hold
charge when unused. I rotate the two batteries after each outing. I
can always count on my second battery to be ready.

Also, I remove the battery from my camera when returning from a photo
outing, charge it, and put it in the bag and move the other battery to
a pouch on my strap. The pouch battery is the next used. I don't
leave any battery in the camera when it's not being used.

I don't think this system is necessary or even beneficial. It works
for me, though. I've never had a battery problem.

I do something very similar to Tony, although I rotate the two batteries
every day. I also take a 3rd battery which I rotate on each trip (i.e.
several day period). This is for "emergency" use only, and tends to
live in the hotel or cabin rather than coming with me. I would feel
confident that battery was well charged after a week, but less charged
after a month.

I have seen one third-party Li-ion battery fail to take charge after
being used for a while, and some 5-year old Sanyo eneloops seemed to
have lost capacity compared to their new replacements. Be aware that
the shelf life, used or unused, of Li-ion batteries is 3-5 years, and
they will show capacity loss.
