I got a 5 pack of cartos for my 808 and thought 3 of the 5 where DOA. After playing with them a little I found that the threading was to deep and the center post was not making contact with the battery.
So I broke out the dremel and started grinding down the bottom so it would seat further down on the battery. This fixed the no contact issue and it started working however I created another problem. I effectively eliminated the airflow slots. So back to the dremel. I cut a couple of new air slots and now all of my carto's are working properly.
