Update on battery markings 22/02/17 

Very soon all batteries from the major manufacturers will come marked with a warning not to be used in electronic cigarettes. Not exactly sure why this is happening now as they have sold these batteries to the industry for years and are still continuing to sell them to the industry now. General consensus within the vaping community is that its protecting themselves if any problems arise from misuse of batteries. We are providing a few links below to reputable websites that rate batteries for use in vaporizers and both sites rate the three batteries we stock very highly. There is also a link to some general battery safety rules when using lithium ion batteries. 

You can rest assured that Ecigify only stock the safest batteries and the safest devices. All our ecigarettes and vaporizers have built in safety protections to keep you safe. We do not stock any mech/mechanical or Hybrid mods as these have no protection built in and can be dangerous in inexperienced hands.
