DSE-905 6 volt

[Uncle Pennybags]

I have 2 diffrent size cr2's. The smaller ones are about 1mm smaller. Maybe that is why some are able to screw body all the closed.

I also got mine from Aqua Vapor. If I use mine with the 3.7v it works fine. If I use Duracell CR-2 it works great, but will only last less than a day. Then the vapor production cuts down to ridiculously low. I measured the batts then and they showed 2.51 and 2.53 volts. Which is wierd because that is still over 5v and it should still work. After all it vapes at 3.7v. The biggest concern is that 2 Duracell CR-2's cost anywhere from $8 - $14. To spend that everyday I might as well go back to analogs.
I did purchase rechargeable CR-2's on-line from Orbtronics in St. Pete, Florida. They will not work in my 905 though. Very strange. The same situation as you Sidora. If I turn it on first then screw it together and try to watch the light I can get it work. Sometimes though it turns on and starts heating the atty without holding the button. Also if I turn offthe main switch it won't turn back on again. However, if I use 1 rechargeable and 1 Duracell it works fine but last only about 2 hours of normal vaping.

Farcry; You're courting explosion and/of fire by mixing batteries and by running unprotected batteries down to where they stop producing. I would recommend reading up on Li battery safety. You'll find much written by the model airplane and flashlight hobbyist guys. Google's your friend.

In case of an explosion, the unvented 905 will act just like a pipe bomb:-(

Also, first and second series 905s unexpectedly turn themselves on and stay on for an exteneded period because of a software error.
