Thanks throatkick,
No; they are "manual" and not "auto" batteries. I think the "sealed" deal is more of a gimmick than anything else. Sure, you don't have that hole right in the center of the threading end of the battery for the liquid to drip into from the carto but you still have that "moat" around the outer edges of the battery so liquid gets in almost as easy.
The draw is "tighter/harder", and as far as I'm concerned they still need to go through about the same amount of regular cleanings (I use isopropyl alcohol), but like I say perhaps it's not the same for other folks that don't use KR808d batteries, etc.
Perhaps they might last longer by it being harder for the liquid to go straight down the middle but I sort of doubt it myself and it's sort of not worth it anyway it the draw is too tight for one's own preference.
Maybe I just need to try some lower resistance carts...
Thanks again,
Norman
