As the title says, I had no problems with the eRoll battery for like 4 months but lately, I kill one a week at least... I am not using the eRoll any more than I have in the past. Good news is that attys seem to be fine. I clean battery contacts with a q-tip periodically and have even tried the re-vive method with alcohol and even spray contact cleaner (leaves no residue for electronics). What gives here? Anyone else having this issue? Are the batteries inferior to what was originally sold? Btw, all of my items I buy for the eRoll are the genuine joyetech ones and I tend to be buying from GoodProphets lately.
