Hello, I just want to make sure you are being safe. There has been a handfull of exploding e cigarettes because of battery abuse. A man recently lost part of his tongue, all of his front teeth and suffered severe burns and eye damage. Please only use matching batteries and chargers and never attempt to charge a disposable.. I don't mean to come on strong, I'm just concerned and looking out for your well being. If you have any questions, please feel free to contact me. Have a good day. Nina
