I am having the WORST luck with batteries! 
I have a newer manual regular size battery that I recently got to replace another battery where I think the switch was a little temperamental and it worked fine for the first few days- well it was never as "strong" as my other original battery, but I know batteries can have their own "personalities" so I'm taking that into consideration. But it worked to put out enough vapor and throat hit to where it worked ok for me at least.
For some reason in the last day or so it's seemed to have very suddenly gotten weaker... I guess you could say? Just suddenly VERY little vapor, but at the same time the carto is getting pretty hot way faster than it probably should... And the vapor I do get tastes way sweeter - just weird and if it wasn't heated enough maybe? (I have tested other carts on it - same thing)
No drops, no spills on it... And it seemed fairly sudden. I don't THINK it's anything I'm doing to it - like I said I have one of my original batteries that worked for me from the start and from day #1 that's the battery I've used the very most, and it still works just as good if not better than the first day. (trust me - I've used the heck out of it already since it seems to be the only VK battery that likes me!) Now I also tried cleaning the battery with alcohol to see if it would help, but that didn't work at all.
Also, like I said this was a replacement I got for another battery giving me trouble- so I really DON'T want to use the warranty again so it doesn't look like I'm taking advantage of it. (well I won't use it again, put it that way- I like some of the products too much to want to give that impression) But at the same time money is getting super tight to where I can't place any more orders for a good while anyways. If anyone can help me figure out what's wrong with this and a possible solution to fix on my own I would be REALLY, SUPER, ETERNALLY grateful!!!
