Question Uwatec Aladin Pro Battery Conundrum

[chaajiro]

I am trying to change the battery in an old Aladin Pro. I have found and followed, to the best of my ability, the steps outlined in various videos etc.

1. I was able to remove the old battery and solder in a new one and connect the red wire to it.
2. Upon performing the battery reset the screen flashed with all display items on for a few seconds, as I believe it was supposed to do.
3. But then, the screen went dead. No display, I was unable to use the contacts to turn the computer on and a subsequent attempt to reset it got no reaction.
4. About 20 minutes later it suddenly beeped and activated to its in-dive screen.
5. This "dive" continued for some time, the highest minute count I saw was 200 or so. Pretty long dive However at some point when I looked it was back at 16 minutes, whether the timer ran out and started over or this was a new dive, I do not know.
6. The next day the screen had gone blank again. I have not been able to reset the battery or get any reaction out of it.
7. I left it for 24 hours, and have now disconnected the battery. But I have no "ERR" screen or anything, it's just blank.

If anyone has any ideas on whether the situation is salvageable, or what else I might try, I'd much appreciate it.

No, it's not.
Haven't given up just yet, but it is looking like I will be "forced" to treat myself to a new one

If you can find a dental curved tip irrigation syringe which will make your job of adding oil and removing air a lot easier and less messy.
Good luck.

For those interested: I took it diving this weekend and, much to my surprise, it turned on upon starting a dive and operated correctly throughout the dive.

It does turn off after the dive, and the contacts still don't bring it to life, so its value as a dive computer is perhaps nullified. I also haven't verified if the second and third dives took into account the data from the first dive/second dives. But as a redundant bottom timer when required, it'll do the trick.

I'll do some digging as to whether I can fix the contact issue.
