Doug B:I don't, however, see the need to use a computer (ie: burn up battery - which takes a $19 replacement battery and o-ring kit)
You are paying a bit much for those batteries, see many sources such as http://www.batterybob.com/product.asp?intProdID=552903&gclid=CN_h4aano40CFRK1YgodJGpr5g
Also, chances are that you don't need an o-ring kit. I have a different Oceanic computer, but my LDS said I didn't need to replace the o-ring, and I never have. Just clean, inspect, and lube very very slightly, whenever you have to replace the battery.
