If a manufacturer is concerned about their batteries being used for unintended purposes (like in an e-cigarette device, and being abused by using them beyond the listed 30 continuous amp limit like some sub-ohm vapers are doing), it could relate if a manufacturer is concerned about possible lawsuits. I brought the subject up as a possible reason why the one Sony rep responded as they did via the email inquirey to confirm battery specs.
Anybody can sue anybody and end up winning huge sums of money, whether we agree with the verdict/court system or not. Even though the "victims" of the Pure Smoker mod probably used the wrong batteries in it and therefore contributed to their own injuries, the lawsuit literally forced Pure Smoker out of business. Perhaps I was reading more into the Sony reply than I should, but my first thoughts were of Sony protecting their butts by reinforcing the unintended application of their batteries and then saying that they were discontinued.
So, we have one email from a Sony rep saying that these batteries were no longer being made by Sony and had been discontinued in production years ago, but there are still multiple manufacturers making a battery being passed on as a Sony with undeterminined specifications. We also have a so-called high-level rep from Sony speak with Illumination Supply and say that they indeed do make the Sony VTC batteries but production was affected by the nuclear power plant catastrophy in Japan, but a replacement facility is now in full production in the Phillipines.
A lot has happened in just a weeks time. Are these two very different stories from Sony representatives just a case of one hand not knowing what the other was doing, or what?

This situation just adds to the confusion of the battery industry in Japan & China, and I'll be observing the subsequent reports that are made in the future.
