I just replaced the battery in my nephew's Uwatec Aladin Pro. An easy if rather messy job.

There's plenty of information on how to do this including an excellent 3 part video series on YouTube (albeit in Italian) which shows step by step instructions :

And a clip showing how to clear the "Err" message :

And even a site dedicated to dive computer battery changes :

However, no-one actually gives you the full part number of a suitable AA lithium battery with the correct PCB pins so here it is...

SAFT - LST145003PFRP
http://cpc.farnell.com/productimages/farnell/standard/BT0357406-40.jpg

The last two digits are important, this ensures two pins on the negative terminal and a single pin on the positive terminal. Easily available from a number of vendors including RS, CPC etc.

RS Stock No.778-1150
Brand: Saft
Mfr. Part No.: LS145003PFRP

http://uk.rs-online.com/web/p/aa-batteries/7781150/

These are good little dive computers very cheaply available on eBay and it's a shame to see them thrown away because the battery is flat.

All the best

Nick

P.S. If anyone knows how to clear the "Int" message from the Uwatec Digital Compass that would be handy :fubar:

what type of oil did you use to refill?

I defo recommend the mktova.cv HowTo :party: web-page: http://mkotva.cz/uw_comp/A_pro_open_en.htm, the page has links to their own videos (non-english, no subtitles, but audio not required, being honest!).

To add to the initial post, who ultimately recommended the SAFT Battery http://www.saftbatteries.com (http://www.saftbatteries.com/), The mktova.cz page also gives a second alternative manufacturer for the replacement battery, Tadiran, out of Germany http://www.tadiranbatteries.de/eng/. Here's the direct link to the Specs Sheet for the Tadiran battery required for the Aladin: http://www.tadiranbatteries.co.uk/eng/downloads/LITHIUM/pdc06engSL-860.pdf (NOTE: the exact part number required is "SL860-PT", the last two letters giving you the correct type of solder tags on the battery, see Spec Sheet for diagram)

For the "What type of Oil" question, first DO NOT be tempted to use Glyceroll. J.J. Cermak is a Chemist from Prague, Czech Republic who has analysed the oil and he describes the Oil as, "clear, suprisingly oleaceous, slightly viscous liquid. Oil fulfils the necessary conditions of electric resistivity. Oil is not miscible with water and other strongly polar chemicals. Oil is fully miscible with the original oil used in such diving instruments". You can purchase compatible Oil from Cermak directly (20euros for a 20ml sample +postage). Cermak's web page(s) are at: http://www.cermaks.com/www/supply/oil-uw-en.html. Contact details are linked off of that page, as are how-to-pay details).

Hope that's of help? :nod:

I have changed batteries of 3 Aladin Pro so far and used Liquid paraffin 100% v/v from Care+.
I still keep one of them, changed battery 2 years ago, and works fine.
