Hate to resurrect an old thread, but my situation is nearly identical to this one.
After not diving for about two years, my wife and I finally booked our first dive trip since I retired in April 2020.
To prepare for the trip, we took both of our rigs to the dive shop we’ve been using for almost a decade.
Since our computers had been sitting for two years, I bought battery kits for each one (her Mares Puck, my Oceanic Pro Plus 2).
When I say kits, I mean factory battery, o-ring, and in my case, four new screws.
Both computers were in a separate plastic bag with the battery kits.
When the dive shop called us, they said that the rigs were serviced and only one of the computers had a new battery. They said they couldn’t find the kit for mine. I informed them that I had shown them both computers and both kits when I brought them in.
It’s about an hour drive from us to the dive shop and we told them we’d be there the next morning.
When we showed up, lo and behold, my battery kit had mysteriously appeared. They farm out equipment repair and had found the kit right were it was supposed to be, and apologized for the oversight.
The battery strength indicator showed 100%, so we decided to dive it the way it was.
My computer performed perfectly during the first two dives, and was counting down when the dive shop hung it up in our locker to dry after all our gear was rinsed.
My computer is on a quick disconnect and yes, I should have taken it back with us, although I don’t think that would have influenced the outcome.
When we got to the boat the next morning, once I got my rig set up on the first tank, I turned on my computer and it was dead.
My first impression was that somehow the computer had stayed in contact with wet or damp gear overnight and discharged.
We swapped it out for a loaner console and completed the second day of diving.
Once we got got home, I opened the battery compartment and, sure enough, it had leaked.
Interestingly, as I was removing the four screws, two came right out and two loosened but wouldn’t run all the way out.
As an aside, I owned, maintained, built and raced cars from the early 70’s through the mid 90’s. I know righty righty/lefty loosey.
I cleaned up the compartment, and stuck a battery in and the computer fired right up.
I subsequently got the battery kit that the dive shop had overlooked and did a full install.
As I was tightening the four screws, two will pull fully down, however the other two will not.
I’m convinced, since this was the first time I had serviced the computer, that at some point in time, someone else over tightened the screws and stripped two of them.
By the way, Oceanic will no longer service the “obsolete” Pro Plus 2.
After this explanation, and I’m pretty sure I know the answer, but for those who have more experience with things like this, with two screws that won’t pull down, what is the likelihood of another leaking failure?
Thanks!
