Facts about the RN4081.

My attys last for months. You were either unlucky, or you may have run it dry. You have to keep them wet, but not flood them.

The PCC for the 510, which you can find at many, many suppliers listed and referred to in this forum, works with the 4081. The only thing is that the batteries vary just a tad in length sometimes (some of them are sold as 4081 and are really DSE103 batteries, etc.), so you might want to research it just a bit and maybe even measure your batteries and make sure before you get one. I have 3 or 4 different types of batteries for the 4081, and 1 type is significantly shorter. They might not work unless you use something to take up the extra space. The best length for using with the 510 PCC is the 4081 batteries that have horizontal stripes (going around them). The ones with the lengthwise stripes are maybe 1-2 mm too long but "might" work with a tight fit. The reason for this is that the 510 PCC charges by letting the lid press the batteries into the charger. Even though I know they will charge in there if they are the right length, I haven't really done it because I don't use the 4081 much any more. (I'm awfully glad it works, though.)

Just spent 20 minutes writing a detailed description about the trick. I logged in before I started and when I went to post it said I was not logged in and ereased the entire post...erggg
Short version: Take the wad and the little cup holding it out of the cart and drip a few drops down the side into an empty cart and the vapor is consistent till the battery craps out or the fluid is cashed! There are reasons for this and more to explain but I'm not wasting any more time till I see the site won't waste more of my time.

Dude, Ya done good. I've been beefing about low vapor and no hit..... This solved it! Thanks a million!

The average is about $14.00 each from US suppliers.
$9.00 each direct from Ruyan (See my post on Atomizers & Batteries.)

FYI: Our replacement 4081 batteries are $11.99 and yes, we are in the US
