Is it on a Sat Sat 1 week trip, or is it a Wed Wed 1 week trip. Cheapest flights are Tue, Wed, Thu now a day...

I have 2 oceanic veo 200's and they seem to be pretty close to the estimate of 50 dive days. Could be 50 dives or 150 dives. I never have used it for a week non-stop diving but I could see the constant on causing problems.
Fortunately those little batteries are readily available and pretty cheap.

Averages are tough, especially because far and away the biggest drain is the backlight, whose use varies so much person to person. I have a Suunto Mosquito, rarely use the back light, and get about 150 diving hours, or a year and a half out of a 2032 Lithium battery.
In estimating battery life, don't forget that Lithium batteries have a shelf-life of about 3 years, and will drain in that time whether you dive or not. If you dive every day and get 200 hours of dive time, you'll get half that if you spread out the diving over a year and half.
Roatan man has it right. The only way my computer batteries seem to make it through a trip, is
when I have a spare and replacement o-ring with me.

Suunto Vytec DS here. 200 dives on mine over an 18mo period. Changed the batteries recently as part of annual reg service right before a week long dive trip, but there were still 3 out of 5 bars left on the battery life indicator at the time
Mine lasted 2 years, but only 50 dives. Age is a factor just as much as usage is.

Mares M2, uses AAA batteries. I had one set last for a year, 60sih dives, I replaced them before it told me to.

I use 2 Vypers, one is serial # around 14000 and the other serial # 600000+
The first battery I had in the older one lasted less than 6 months and then I realized what was happening. I wasn't rinsing and drying off the water contacts after each dive. And since I dived various live-aboard trips in that period the computer was staying turned on for days at a time.
After I changed the battery I made sure that after every dive I would rinse off the terminals with fresh water and then blow them dry with air from the cylinder. The next battery ran for years even with regular use of the computer.
Now the interesting thing is that Suunto obviously made an adjustment to the sensitivity of the water detector on the newer versions because the moment my newer Vyper leaves the water the contact indicator goes out without any rinsing or drying.

Has anyone noticed if the battery indicator is accurate as to when it will die?
