There's nothing to screw into the battery. I only have the stuffed cartridges with no atomizers. So, I guess I only have half of the two pieces. ARGH...anyway, would it be feasible to just chuck these? The atomizers (the metal screw thingies) look expensive. Seems that I could just get blank cartomizers for less. Right? Any suggestions?
Would the 510 to 4082 adapter allow the carts to become interchangeable? In other words, would I be able to use either the 4081 or 510 cartomizers on my 4081 battery? If so, that would be awesome. Doesn't the 510 carts hold more juice?
I would keep them in case you ever buy atomizers. Then you can use new filler inside the cartridges and drip juice into the filler. (Some of the more popular filler replacements are Fluval polyfil and Marineland blue foam from the fish section in pet stores, if you decide to use cartridges with separate atomizers -- but cartomizers are recommended more often.)
There are two adapters related to 4081 threads: 510-battery to 4081-atomizer and 4081-battery to 510-atomizer.
If you only have the 4081 batteries, then you would use the 4081-battery to 510-atomizer (or cartomizer with a built-in atomizer) adapter to use the 510 cartomizers with your 4081 batteries.
The 4081 cartomizers wouldn't need any adapter to screw into your 4081 batteries.
There are several different kinds of 510 cartridges and cartomizers, so I'm not sure which ones you're asking about. The Boge 510 cartomizers hold about 1 to 1.2mL of liquid.
