Hi. This is far beyond any laws of averages to have that many problems, with that many batteries, in such a short time. Something is not right here but without knowing more about which vendor it is and what they sold you it's hard to comment beyond general issues on what might be the source of the problem.
LR attys or cartos can shorten the life span of batteries as the resistance of the devices drops even lower with age - in effect creating a short circuit. Some vendors are more prudent than others about warning you to NOT use particular LR devices on certain batteries that aren't really made to handle it. This is one possibility for your scenario. A defective charger - if the same one was used on all these batteries - is another possibility.
What has the vendor had to say? Have you contacted them?
I have emailed the vendor, as they did not answer the phone today, though I did call during normal business hours. I have not had any response yet, so it will likely be Monday.
Like I said before, we thought the previoius 3 batteries that lasted just under a month had stopped functioning due to a carto. It is not LR, but we have used ressurectors (as they were recommended to us by several on the boards) on our batteries as well. 2 of those were my batteries, and were only charged on my charger. We still have 1 of the original JoyeTech batteries still functioning, which has always been charged on his charger and has had resurrectors as well as the same model of cartomizers that we thought might have been the reason for the previous malfunction. We threw that carto away, and have had no other issues out of that model. (eGo Clearomizer from esmokeytreats). <<<Is not the vendor we got our batteries from.
At this time, I am opting not to list the vendor involved, as I do not know what all may transpire with them, or my insurance company, or any legal reprocussions. I don't want to be accused of slander. I highly doubt they sold me defective products on purpose, but it does seem that they are selling products of inferior quality.
