So after doing a little digging of my own and consulting with my shop battery supplier a couple days ago (I work at a b and m) I have pieced together that sony has not produced vtc batteries for going on like three years but have let subcontractor companies build them in Japan until the Fukushima (not sure if I spelled that right lol) incident and have since moved production into the Philippines and even though they are still technically "vtc" that QC is garbage compared to what it was in Japan. Can anyone else confirm this? My battery guy has said to wait it out for another couple of months and make sure nothing bad happens before I start stocking them in store again and for the time being should just stick with LG HE2's. After a couple other posts I am pretty sure that this is where I will stick to for the time being as LG is more likely to have better QC than anyone else at the moment and I feel more comfortable vaping on a known name than an unknown name...(although I do have and use a couple others, I do still prefer my LG and sony batts at the moment)
