Let see if I can answer all these questions -
Total dives - 121 - Total hours - 53, so estimate 1/2 of that for each battery
The first time it gave me some warning, and I had time to change the battery. This time it was dead for the first dive of the year after sitting since November.
Battery shelf time *could* be an issue.
I never use the compass or backlight. Even when I night dive, I use my flashlight.
It never stays in dive mode, always goes to time mode fairly quickly.
