I got 7 AI rEvo cells in mid April 2007. They were manufactured in October 2006 according to Paul.

Now six of them are dead.

Three of them were opened last summer for indoor use and DIY setpoint controller testing. Now two of them are dead. They lasted less than a year in use!

I installed one in my Inspiration in mid June. It worked ok. Last week I serviced the unit for first dives this year. The only AI cell was dead.

I opened the last 3 bags of AI cells and 2 of them was dead. I installed the last working one into my Inspiration but it died on the first dive. It started showing reading .2 above Teledyne cells. After 10min it started to show reading below Teledyne cells. After 20min it showed reading .6 below other cells.

All Teledyne cells have worked just fine. 1.5 years in service kit or closet, 12-18 months in rebreather use and 1-2 years in oxygen analyzers.

The cells have only 1 year warranty after manufacturing.
Paul @ rEvo-rebreathers promised a small discount on Teledyne cells but thats all.

Let see what AI says after I email them. 18 month life for unused or used cell just is not enough.
