Battery is a possibility it was reading 57%.

----------------------------------------

57% of capacity or 57% of voltage? If it's capacity (i.e. ampere-hours) it
does seem surprising to have let you down, but if it's voltage then it is
well past the time to change it. After all, you wouldn't expect to start a
car on a battery that was so clapped out that it only produced 7 volts
instead of 12.

I gave it up when I stopped diving the twinset. 8-)

The two gauges were to cater for re-planning a deco dive
after a serious breakage leading to closing the manifold.
Also, after having an SPG hang up on me, some confirmation
of readings helped.

The alternative is to rely on my diver skills and training
but, once I have a couple of bar of Nitrogen in my brain,
I see no reason to trust them.

My Buddy & I have replaced our three Air-X's with Air-Z's now. They all
failed around the 40-50% battery-life mark. The Air-Z's are fine. I have
done around 200 dives on my Aladins, my buddy (an instructor) has about
2000 on hers! We both use a backup contents gauge. If diving solo I also
wear my Suunto Spyder.

There is a number of reports of similar behaviour on the net
(including one from myself). The problem with your line of argument of
course is to show that it is really the battery that had failed. My
local dealer (who is usually trustworthy) claims to have seen Aladins
that have a proper low battery warining on the display and that all
the ones with 'Err' have a fault in either one of the sensors or of
the PCB board. The problem with the fix is not so much the price
(roughly 80 Euros given that I have taken my Aladin to seven years of
diving) but the time of several months it takes
Uwatec/Scubapro/Johnson Outdoor to fix it.

In the meantime, I've bought a Suunto Vyper off ebay, see my other
posting.
