I don't use auto batteries, I prefer manual. However, my parents only use auto. As they are not tech savvy at all, I am posting this on their behalf. They were customers of another company. The auto batts they were ordering used to have a hole in the center. That changed. I had them give Vapor4Life a try. The auto batts from Vapor4Life came sealed as well. As a former Vapor4Life auto batt user, I knew they were not always sealed. So, I deduced that this changed on a much broader scope. I assume there was an issue with liquid getting inside the batts and causing problems. Is this the case? I'm asking because, while they still vape, still prefer auto, and still order from Vapor4Life, they claim the new auto batts performance stinks in comparison to the previously unsealed. Any thoughts, insights, remedies, suggestions, etc. will be much appreciated and passed along.
