Ok I have done some research and actually installed a new battery in my Aladin Sport. There is a Italian (yes it's in Italian but you'll get the idea) 3 part video on Youtube on how to replace the battery in an Aladin Sports Pro search Aladin or Bricosub (the author). It takes about 30 min to watch in full but is very good despite being in italian. Time wise it will take you about 30 minutes watching the video and proceeding carefully. The video will show you how to do it. These notes wil help you deciher the process (which I had to do).
The Sport and the Pro are the same when opened. I wouldn't be surprised if the Nitrox version was also the same just software/programming change with the model. Some things worth noting.
Uwatec will service them here in Australia it costs $175 OUCH!!!! Not including postage.
The battery is a LR07 which is also a LS14500, SBAA11AX and may have other names. What you are chasing online is a 3.6Volt AA size Lithium (lithium Thionyl Chloride (not rechargable) battery (NOT lithium ion). It comes with solder tabs, plain and with wire out the ends. You want the wire out the ends ( I made the mistake of ordering tabs and had to reorder wire). Cost about $8 per battery.Don't waste time trying to solder on wire unless you really have to, its a pain I tried it!
The case is easy to open. slide a thin blade down the sides and the back comes off. Underneath is the rubber back. Don't poke through any of the four holes in the hard back you'll puncture the rubber seal. You will leaver out the seal (carefully!) to expose the insides.
It is oil filled. Don't let this scare you. The oil is mineral oil. Wikipedia lists mineral oil as parrafin oil, baby oil etc, it's called various things in various places. Take the time to read wiki. Don't bother trying to save the oil, you can just buy a liter ($17 Aussie dollars from Bunnings ...Aussie version of Home Depot) of it and refill it during the service. Best guess is that it takes about 50 ml to fill. The oil is non electrically conductive.
Make sure when finished and resealing you release all the air bubbles (refer to part 3 of video where he tilts the unit submersed in oil)
The reset requires a 3 volt battery. These are expensive ie $10. Save your self some cash and use 2 ordinary 1.5volt AA batteries in series (end to end) $2 will buy you a 2 battery holder like you see in battery operated toys (go to Radio Shack or Dick Smith/Jaycar in Australia) which will save you soldering.
This should allow you to watch the video and fix your computer. You will have to desolder 3 joints and resolder 2. It's not hard and for $175 I for the life of me can't figure what the tech's are charging for. High school students solder harder things in school. If your anyway mechanically/electrically inclinedeven slightly you'll be fine, If you have to call for roadside assistance to change a car tyre I suggest not trying it!!Good luck and post here if you succeed, I'd like to know if anyone actually benefits from this.
This will be cross posted to Youtube as well.
