Dive Computer Service

I have a Suunto Mosquito that is 7 years old and hasn't been wet or even worn in 5 years. I removed the battery and I didn't see any acid leaking or anything from the lithium battery.

What service should be performed prior to putting this back into use? I could buy the battery kit with new oring and all but I'm wondering if it would flood or be miscalibrated somehow when I get it wet.

No calibration is required.

The only servicing needed is...changing the battery. Buy one of the official Suunto Mosquito battery kits that has a new o-ring, battery, gold-colored metal piece, and battery cover. The new battery cover is necessary because it's very easy to mess up the existing battery cover when you're removing it with a coin. Trust me. You'll see what I mean when you get around to doing it.

In the past, I've been able to re-use a battery cover for a couple of battery changes before I scuff it up too much with the coin.

I've changed my battery 4 times so far. I did all of the changes myself. I never pressure-tested the computer afterward. Just pay attention to detail, don't jack up the computer case trying to remove the battery cover, and re-assemble everything properly. The hardest part of the whole process is removing the old battery cover. If you've already done that, then the rest of it is a piece of cake. After the battery change, I throw the computer in a bucket of fresh water to see if it's water-tight. After that, I take it for a test dive in the ocean.

I've replaced the battery a couple times in the past and I agree with you. I was just wondering if there was anything additional I might need to be concerned about since the computer has sat on the shelve for so long.

It should be fine,I use to have one but I move up to a D9. But you should have the depth tested in a chamber to make sure it is accurate.

Meh. I recommend just comparing it to your buddy's computer on your next dive.

How much does a dive watch chamber test cost? I suppose it might be worth it if it revealed a leaky battery compartment seal and it gave you an opportunity to fix the issue without flooding the computer first.

Thanks all. Yes, I've always had a computer and a SPG and would cross check the depth with my SPG and my buddies SPG.

That said, I think this computer may not dive again after all. Upon close inspection I see a small crack in the bezel ring that sits on top of the face plate. I don't know if this would cause a leak but since I don't recall the damage occuring I'm not sure how severe the impact was.

I really just need a bottom timer for my trip. I wonder if I should even spend the money on getting a new battery and take a chance on it flooding or if I should just leave it on the shelve to get fixed another day in case I get active in diving again.

My trip is in a week.

If the shop changes the battery then it’s included, other wise they would do it for free are a couple of dollars.

Hmmm. How much did you pay for battery kit + labor + pressure test for your Mosquito (when you had it)?
How about for the D9?

For some crazy reason, I figured that I was saving money by changing the battery myself. I have no qualms about doing the service on my own, but I never bothered to pressure test after opening up the case. I would certainly be willing to spend $2 on a pressure test. I may have to re-consider how I've been doing things.
