    I picked up an old Aladin Sport dive computer at a garage sale recently. The battery was dead so I took it to the Scubapro dealer to get it changed out. He told me it would have to go to the factory to change the battery because it was so old. He told me that it would be about $150-160 to do that.

    I am curious...is it really that much to get the battery changed on that old computer? I don't mind paying the price for a cheap backup (I dive with an Aeris T3), but that seems a bit excessive.

    Hi from padi613
    In your May post you state that the cost of renewing the battery was quite high.
    You will of now had the computer repaired or thrown it away. For the record batteries for this unit cost aprox; $7-10. repair service times in the UK are $50-60.
    In my work as a qualified scuba technician I have carried out battery renewal on various dive computers and if I can give any info regarding any problems post your comments.

    I see its a really old post, but if my memory serves me correctly, this battery change was a relitively simple affair. On the side of the unit there was a small door with two small pin holes, using an appropriate tool, simply unscrew the cap, unsolder the old battery and solder on a new one.

    Screw back the cap - 15 minutes start to finish - tops.! - in my day we did hundreds, it was a very popular unit and almost indestructable.


    You could even source the battery at a specialist battery store for a fraction of the cost of one from Scubapro, ask them to affix solder tabs on each end which is nothing new to them, and away you go, battery cost from a specialist store would be no more than $7.00 with tabs.

    That is only on the earlier models. Later units have no opening. It can be done but since the unit is oil filled it is a little more complicated.

    Aladin Pro, Aladin Sport - DIY battery exchange

    I am going to try it on my Aladin Pro but have not done so yet.

    Sure GRF88, thats correct, the newer oil filled units are not really "do it yourself" operations, I just thought as it was such an old unit (according to the shop) it was probably one of the user changeable units.

    Its a very easy change grf88, no need to worry, wont take more than a few minutes if the soldering iron is hot before you start.! ;)

    I am not expecting it to be quite that easy, cracking it open and saving the oil might take a little time. Mine does not have an access door either.

    Sorry, my mistake, I was thinking it was the older "door" type.

    Opening the oil filled unit is not difficult, saving the oil is though, you almost always loose some, maybe just think of some new oil in store to top up.?
    I still think another issue may be removing all the excess air afterwards, I am concerned you may find you end up with small air bubbles in the unit, not necessarily a problem operationally, just maybe a bit irritating, access to a vacuum unit would be ideal for this.

    I was told today by my scubapro dealer that they can no longer send my Aladin Sport dive computer in for a battery change.
    So, I've been searching for info on changing it myself.

    Just did a search for battery LR09 and interstate batteries has one with a different number, but is used in dive computers, so I sent them an email to find out if it will work for my Aladin Sport computer.

    Can anyone tell me how to open it? There is no door on the side. It is in a console and I don't know how to get it out.

    Can you post a picture of it so we know the model.?

    A pic always makes it easier to identify, then you can be sure of getting the right info.

    Hi I'll jump on the back of this thread. My Aladin Sport was in a console too. Look at the sides there are 2 pins (will stick out one side or the other) at either end of the sides of the rubber console. I used a leatherman set of pliers to grasp and pull out. The computer then slides out. Easy part done. Now the same quesion as the others how do open it and if there is oil how do I deal with that. Would love a step by step instruction if anyone can help. Will attatch photos to help. Also is it still possible to get a wrist strap?? Much more convenient than a console. Thanks in advance.

    P.S It won't let me post links to urls until I have 5 posts or more, this is my first!! So look at my gallery sorry for the inconvenience.

    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.
