The OSTC consumes 1-2%/Week in st.By. So yes, if you don't dive for months remove the battery from the OSTC Sport.

Because battery % are not based on cell voltage. The % value is computed, not measured.

Heavily depends on ambient light and display brightness setting. I carry an OSTC3 backup in my pocket (No light, ECO setting) and the battery is fine for more then 100hours of use now. With brightness HIGH and much ambient light you'll get ~30hours.

Depends on the level of reliability your dives require. I'd recommend to replace the battery at 25% at the latest.
